Recent experiences with Cryptocentrus cinctus and Alpheus
bellulus. 8/1/17
Hi :)
<Borja>
Just sharing a curious experience. A year or two ago I inherited an
unlikely pair from a fish store that was closing down.
An Alpheus bellulus and an Istigobius sp. I say unlikely because
obviously, despite the claims of the LFS guy they were not symbiotic,
although the Alpheus never attacked it. Anyway, I brought them home and
added them to my
tank (330 litres, 10 cm DSB).
<Various shrimp gobies DO associate w/ diverse shrimps in captivity...
outside of pairings that are known to occur naturally>
Of course the Istigobius never paid any attention to the Alpheus (as
expected) and the only thing it has done
is to triple its size (it was tiny when I added it, it's really fat now
and it has reached 10 cm).
However I was surprised by the Alpheus. First, I didn't have a symbiotic
goby in the tank at the time, but I have
a group of three Ptereleotris zebra. They of course burrow in the DSB.
What was curious is that they didn't seem to bother when the Alpheus
invaded their burrows. The Alpheus also ignores them except for a
protesting click
now and then, I guess it does it when one of the "hakes" (I call them
hakes because they are rather large) blocks
its way.
<Neato>
Everything has been peaceful since I introduced them. So, first curious
observation, as far as I know there
hasn't been any aggression despite being a reef tank with several fish
species and a Stenopus hispidus. I guess
the Alpheus doesn't venture far from its burrow anyway.
<Some don't>
The second phenomenon happened two weeks ago. I found a Cryptocentrus
cinctus at a LFS and brought it home.
From my past experiences I assumed that it would settle peacefully upon
finding a proper sand bed and an Alpheus burrow. Surprisingly, a couple
of hours after introducing it I found it in panic, circling the tank
close to the surface. There were no torn fins nor any signs of
aggression. It was clearly stressed, having turned almost white.
<?>
I just let it be assuming that it would eventually explore the bottom
and find the burrow. Next day, however, I found it in the sump (which
means it jumped but, thanks to a net covering the tank in order to
prevent Ptereleotris incidents, it fell into the overflow). I insisted
and put the fish into the tank again, this time luring it with my hand
trying to guide it to the Alpheus burrow.
And that's been it, I have seen no signs in two weeks, so I assumed the
worst. I couldn't check out the burrow easily because it was oriented in
the wrong way, I couldn't peek inside. Until today! The Alpheus has
decided to do some renovations (I find their sudden renovation sprees
rather amusing) and the burrow was oriented towards the front glass.
And, surprise! Inspecting with a flashlight, a calm Cryptocentrus was
staring at me from inside the burrow.
I hope it will venture out more when it grows (it is tiny, 6 cm or so).
Adding food to the tank I've also seen it feeding rather aggressively
(frozen Mysis and krill) so i guess it's well
settled now.
The good thing is, I have a goby-shrimp pair again and it seems they are
doing fine with their tankmates.
However, any clues about that initial panic reaction?
<Not from here. Don't know what might have been going on>
As I said, my tank has a DSB and less than one third of the sand surface
is covered by rocks. The sand surface is really obvious.
For the record, the tank mates are: 1 Zebrasoma flavescens, 1 Centropyge
bicolor(*), 4 Sphaeramia nematoptera,
4 Chromis viridis, 1 Pterosynchiropus splendidus, 1 Pseudocheilinus
hexataenia, 3 Ptereleotris zebra, 1 Gobiodon
histrio, 1 Istigobius sp, 1 Chryspitera hemicyanea, 1 Acreichthys
tomentosus,
(*) The same bicolor mentioned in my messages from 2011.

Wrong id: Shrimp Goby POTD; and Alpheid comp. q.
5/27/17
Hi guys,
<Dr. Andrei>
Was browsing WWM for some answers.
Noted on
http://www.wetwebmedia.com/SWPOTD722.htm
The first photograph tagged "Amblyeleotris latifasciata, the Red-banded
Shrimp-Goby. Western central Pacific in distribution. To a little over
three and a half inches in length. Occasionally imported as an aquarium
species. Bali 2014" shows an Amblyeleotris diagonalis pair with a single
Alpheus bellulus. No A. latifasciata in there.
<Ah, thank you for this correction>
Now to jump to the my pain:
I have formed the forth Amblyeleotris latifasciata pair and managed to
form a Alpheus bellulus to go on the same team.
They've went through a six weeks quarantine with an Alpheus bellulus
shrimp, then moved in my RSM130.
All was well for a week. This video is from yesterday
https://www.youtube.com/watch?v=ooPVVypqxXY and as you can see they were
a happy quartet.
This morning, one of the shrimps was displaying erratic behavior
(leaving the nest type), going around the edges and swimming into the
open, ignoring any goby protection offer. An hour later, he was fully
fitted inside one's goby mouth. The other goby was picking pieces, so
finally the shrimp was successfully swallowed.
Now it's job as always, with a pair of Amblyeleotris latifasciata and
only one pistol shrimp.
<Mmm; I'd stick with this arrangement, having just the one Alpheid>
The tank is a RSM130, is six months and two weeks old, livestock is -
pair Amblyeleotris latifasciata with (now) one Alpheus bellulus, 1x
Ecsenius stigmatura, 1x Ecsenius pictus, 1x Lysmata amboinensis, 4-5x
Paguristes cadenati, 2x Cypraea tigris, 5x Monetaria annulus, 6x Turbo
fluctuosa, 20+ Nassarius vibex (20 adults and now countless babies), 3x
Nerite sp, some Stomatella.
Last water parameters (from yesterday):
- temp 27.5°C (termometru JBL)
- pH >8.0 <8.3 (Salifert)
- Alk 9.3 dKH / 3.30 mEq/L (Salifert)
- NO3 25 mg/L (Salifert)
- Ca 380-390 mg/L (Salifert)
- Mg 1200-1230 mg/L (Salifert)
- SG 1024.6 (Hidrometru Tropic Marin)
- PO4 - no clue, I run some Rowaphos in a sock though and have no algae
growth on the glass anymore
The tank journal link is
http://www.acvariu.ro/forum/posts/list/80/36966.page , unfortunately the
forum is in Romanian, also littered with NSFW photos (my forum members
appreciate everything natural and beautiful, not restricted to fish) -
:blush:.
I do not know what to make out of this, but my previous pair of A.
latifasciata consumed both their shrimps at the same time within a week
of being moved in the same RSM130 tank from a smaller tank where they've
lived peacefully for a lengthy (+ two years) amount of time (see here
https://www.youtube.com/watch?v=CNJ1z6DDuk8 ). Needless to say, I've
lost that pair sometime after the incident (upon return from a ten day
holiday in January 2017, the girl stopped thriving, became emaciated and
wasted away, the male followed a week later - stopped eating upon the
death of his partner). Video prior to introduction
https://www.youtube.com/watch?v=G8gSh6hCBIQ with very excited gobies
and soon after introduction in the tank
https://www.youtube.com/watch?v=lpblO17FYfU
My theory around these killings is that the Amblyeleotris latifasciata
as a species is developing more marked attachments then other
Amblyeleotris species and upon being left they become jealous. I feel
these fishes suffer when I'm not taking some time near the tank as they
are always attention seekers and this goes beyond begging for food (if I
just throw the food and neglect them they keep flashing). Also, they
cannot stand being left by their shrimps as it sometimes happens and
upon no other alternative, proceed on consuming them. I must also
mention that they do not hide when I introduce my hand in the tank and
that all the transfers (from the LFS bag to tank and from tank to tank)
have been made by hand.
Please feel free to import and use the photos and videos from my YouTube
channel and from my tank journal at your own will.
Kind regards,
Andrei
<I'd offer a bit more meaty food/s more frequently... pipetted directly
to their area; and hope for the best here. Bob Fenner>
Re: Wrong id 5/27/17
Hi Bob,
<Dr. A.>
Thank you for the quick answer.
<Certainly welcome>
I'm aware there is no clear cut answer, just wanted to leave a trace of
this unusual behavior.
<Ahh; good>
I'm currently feeding them (and my other four nano tanks) a mixture of
frozen food (Gamma Marine Quintet: Mysis, brine shrimp, krill, seaweed,
razor clam) at each meal with some occasional dry food snacks to calm
down the begging. They are not slim by any standards.
<I see>
I'll come back if there is any progress or progression on this.
<Thank you>
Kind regards,
Andrei

Alpheus Shrimp- Pistol Shrimp Compatibility
2/19/16
Dear Bob & Crew,
Thanks again for your on going passion for aquatics! Still waiting for a follow
up to "Reef Invertebrates"!
<Ahh! I would tell you that I've been working on; and am almost (within a few
hundred hours) of finishing the two Reef Fishes books/volumes; and am
serializing the "Corals" tome via the UK magazine UltraMarine>
I had a brief question today. I had a Alpheus bellulus tiger pistol shrimp in my
155g reef tank but discovered that it was killing most of my snail population.
<Yes; common... can/will kill hermits, other small crustaceans as well as small
fishes>
It was a rather large pistol, going on 3", with mostly gray stripes- not much
coloration. It has long since been removed. I have seen many smaller, more
colorful pistols (not sure if they are the same genus) and was wondering if they
would be more compatible with snails.
Thanks so much!!Joe
<Not as far as I'm aware. The predatory behavior is very likely a function of
size (as you state); as well as hunger and opportunity. IF trying another, I'd
start it small and keep it well fed (as in with a feeding stick). Bob Fenner>
Caribbean Pistol shrimp mowing Torch
3/28/15
Hola WWMCrew:
<Que tal JG?>
You should know that your site provided great inspiration and therapy to
me after returning from a deployment in Iraq.
<Ah, good>
Reading your site gave me the knowledge and courage to
start my tank back up - so thank very much for what you do
guys.
<A pleasure to share; thank you for your encouraging words>
And again I turn to you all for help. I've got a Caribbean Pistol -
about 2.5-3 inches (he snaps away at night). Got a goby for him,
they don't like each other.
<Of all the things I can't seem to get a decent pic of... after diving hundreds
of times all over the Trop. W. Atlantic; are the Alpheids found there>
I also caught him chopping off the tentacles to my torch coral?!
<Yes; have seen these little bugaboos trimming Condylactis in the wild>
He's nearly killed it now. I can't find any information
online about this behavior and I know many hobbyists keep
them in their reefs.
what do you think? -
<Time to trap and move that bad boy/girl>
thus far that is his only coral target. Perhaps something I
can purchase will eat him because its doubtful I'll be able
to get him out.
<See WWM.... ah here:

<Welcome! Bob Fenner> More re Stonogobiops; now symbiotic shrimp matching, comp.
w/ other livestock 10/1/13
Hi Bob,
Sorry to keep bothering you, my pair of high fin goby's have taken up
residence In the Jawfishes old home, and they are being very timid and
not coming out for feeding
I was thinking of getting them a pistol shrimp to help with
digging but was wandering what type of pistol will pair with them? We
have a pair of mandarins, 1 Jawfish, and 2 bicolour blenny's.
<... I'd very likely skip placing an Alpheid here... Too likely (highly)
to have trouble, even if the Pistol is commensal to mutual w/ the
Stonogobiops (nematodes BTW, not yasha)... You can/could look up which
species are found "naturally" together... The real trouble is size of
the system AND the other fishes here. Too much probability that the
latter would/will "get punched"... Keep reading. B>
Pistol shrimp issues; non-compatibility of currently offered
spp. 8/31/13
I was browsing your site looking for other information when I thought I
would check out the information on pistol shrimp. I found there lacked
some crucial and important distinctions in the information provided.
Lately there has been a flood in the pistol shrimp market of shrimps
belonging to the *Alpheus armatus* species complex. These
shrimp, despite what most LFS say, rarely play nice with gobies as they
naturally host with curly cue anemones. This has been giving a
lot of people and gobies unnecessary grief. People need to know that not
all members of *Alpheus *are goby lovers
* *and trying to force them into this unnatural relationship may end
very badly.
Thank-you,
*Jen*
<Thanks much for this valuable input Jen. Will post/share. Bob Fenner>
Pistol Shrimp? 2/25/13
Hello, I've had a case of the disappearance of two burrowing fish. I
have a 120 gallon reef with a yellow head wrasse, a slip<pery> dick
wrasse, a whitetail tang, a blue tang (Caribbean) and two blue Chromis
and a royal gramma. In June last year, I bought a Pearly JF. He
dug a burrow in front of a rock in the center of the tank, and was
visible throughout the day.
His fins were slightly ragged, but he ate Newlife Spectrum pellets and
Mysid. He seemed very happy. Then, about 1.5 months later, he doesn't
cover up his burrow at night and peeks out from below the sand. Mind
that he had a good SB to dig in. The next day he's gone. No signs of
aggression from tank mates, no body, no new burrows. I give it some
time, he doesn't show up. His burrow was empty. Then, in December I
bought a diamond Head goby.
He dug a burrow in the same exact spot and the next day he was gone. Now
I hear popping/snapping all day and night. It's audible over the radio
and is distinctly different from water trickling. I have seen neither
hair nor hide of anything looking close to a pistol or mantis shrimp in
my tank, and curiously enough, my cleaner shrimp is happy as can be.
<What species is this cleaner? Stenopids are fish eaters>
I have tried traps but nothing ha<s> shown up. If this is a pistol shrimp,
it's definitely Atlantic, which Is bad news. I have a hard time
believing it's a mantis because it's stayed out of sight for so long.
<Mmm, well, there are some small, more reclusive species of
stomatopods...
or could even be some variety of aggressive, largish bristle worm/s at
play here>
Coincidentally, I saw a hermit crab go bouncing down my rocks,
accompanied by a cacophony of popping whenever he bounced, but I doubt
he made that sound.
<Me too>
(I am positive that neither fish jumped out of the tank and did not make
it into the overflows) I've officially called off the search for the
fish and will probably find out what caused their demises before I buy
another burrowing fish, which I love.
Thanks, Luis.
<Try other traps. Have you read re on WWM? Bob Fenner>
Re: Pistol Shrimp?
Thanks for your reply. The cleaner shrimp is a skunk cleaner shrimp,
mostly keeps to himself, cleans the fish every now and then.
<Are almost always safe>
I haven't read too much yet, but I'll need to find the criminal. I'm
thinking of redoing my rockscape, that should probably be when I should
look for the shrimp, right?
<Yes... do wear gloves... some folks splash soda water into cracks,
crevices to flush out hiders>
I'll try traps. I'm thinking about the bristle worm part...I don't think I
have any monsters yet...but I could be very wrong, the tank is a year
old.
<Have seen some really neat footage of co-inhabiters w/ fishes in
tubes...
Including large bristleworms. B>
Re: Pistol Shrimp? 2/25/13
I know the popping is definitely a clue to what's causing the
disappearances. Do you think it's a pistol shrimp or mantis shrimp?
<Could be either, or both>
It's not so much as a knocking as a popping, but I know that water sort of
distorts sound.
<Ah yes. B>
Fire fish compatible with yellow
watchman goby and pistol shrimp
Hello WWM crew,
My name is Erika, I always read on your site and try to solve any
issues that I have encountered. Thank you!
I have a 75 gallon soft coral reef that's been running for 3 years,
it is a natural system with about 130 lbs of live rock, a deep sand
bed, a Remora pro skimmer and an Hob refugium with a full cleaner crew
at work. I have a false percula clown, pajama and Banggai cardinals, an
engineer goby, 7 small Chromis, a Heni butterfly, a six line wrasse and
a yellow tang. I do regular water changes and add a daily dose of part
a and b solutions and my parameters are good. I have two questions for
you: 1.- About 3 months ago I bought a yellow watchman goby and a
pistol shrimp and the goby died in QT (Thank God for QT), so I bought
another goby plus a fire fish.
<Mmm, what species of Microdesmid? Most are very social... See WWM
re the Selection/Stocking (FAQs)>
After 6 weeks of qt I placed them in the DT and to my great joy saw
that the yellow goby found the shrimp's cave and they became the
best of friends. Well yesterday when I was feeding the fish I saw that
the Firefish came out of the cave also, is this possible?
<Yes>
Can the 3 of them co-exist as friends?
<Affirmative>
I tried to find something like this on WWM, but could not find
anything.
2.- my other question is about a crab, I don't know what kind it
is, it is regular brown color with two claws. Up to now it seemed fine,
I do think it ate my Zoas that I had, is this possible?
<Indeed it is>
What I am worried about is that it has grown a lot and I'm worrying
it could get to a size where it will eat my other fishes at night or
the other shrimp. I used to have two peppermint shrimp that disappeared
and I'm thinking it was the crab. What do you think I should do? It
is always in the rock crevices so I imagine it is super hard to
catch.
<I would bait/trap it out and remove. Please read here re:
http://www.wetwebmedia.com/swcrabcompfaq2.htm
Thank you so much for your help,
Erika

Unexplained Death Of A Beautiful Tang/Zebrasoma
xanthurum/Health 4/20/2011
Good morning, crew!
<Good morning to you, Kerstin.>
I haven't written in some time, but I just lost my Purple
Tang, and am at an absolute loss as to what happened, or if I did
the right thing or not.
I included some pictures in the hope someone can provide some
insight please...or at least commiserate in the loss of this
lovely fish (or even berate me for my stupidity...). I apologize
in advance for the long email.
<No problem, the more info the better.>
The first picture shows my tank from last September. It is a
92-gallon corner tank, it has been set up since November 2007, at
which time I moved my inhabitants from a 3-y.o. 29-gallon tank.
Fred, my purple tang, was originally in my 29-gallon tank, and I
knew it was too small for him, so I knew he'd love the bigger
tank; in fact he's been happy in there for the past 3-1/2
years. His current co-inhabitants were: <were or are?>
2 Centropyge - one a Cherub face dwarf (have had over a year),
the other a one a Flame Angel (close to a year now)
1 Lemon Goby (in tank for over 6 months)
2 Clown Fish (both in tank over 6 months now)
1 Royal Gramma (who more often than not disappears for days/weeks
at a time, and always lives behind the center pile of stone
pictured below...has currently been out of sight for about 3
weeks, but that's nothing new...has been there for about 4-6
months)
1 Brittle Starfish
1 Blood Red Shrimp
about 23 corals (I no longer have either of the disc corals in
this picture).
The 6- <Six> Line Wrasse in this picture was caught after
Christmas - I was tired of him being the emperor and terrorizing
the entire tank.
<Not easy to catch, are they.>
Recently I had purchased a (in hindsight) too-skinny Blue Faced
Sleeper Goby, and he passed within a day. In discussion with the
LFS, we think he truly was just too skinny and beyond rescuing.
At this point, I check water values - Spec. Gravity slightly high
at 1.028, Calcium low at 196,
<Very low, this has to come up to an acceptable level.>
Alkalinity high at 9.5 dkH, and Magnesium normal (in the mid
1300's I believe).
I worked at lowering my specific gravity a little. About 2 weeks
later (last week on Friday), I purchased 2 more Citron/Lemon
gobies and a matched pistol shrimp and goby...I did the research,
and thought these would work well with my tank...they were to be
my last purchases. Everything I read also indicated they did not
do well with quarantine, so I did not do that with these fish. I
spent about 5 hours acclimating them, to make sure they were used
to my tank water.
Well, strange things seem to be going on - and I am now going to
research more - but would love to have inputs - because I just
have no clue even under what terms to search for this. I did look
right after this happened, but "Fish jumped/not swimming
right just doesn't seem to work well.
As I mentioned, my Royal Gramma often disappears from sight for a
while.
However, now I am beginning to think maybe there's more to
it.
<Does the fish come out during feeding time?>
Over the past year, my shrimp population has decreased from 4
cleaners, 2 blood reds, and a mated pair of Coral Banded to the
one red shrimp...thought it might just be old age, as I have had
some of them from the beginning of this tank.
<Shrimp/crustaceans do require iodine/dide dosing to help with
their molt, and depending on the specie of Brittle Star you have,
this animal could be the culprit. The Green Brittle Star of the
genus Ophiarachna is a notorious fish/shrimp eater and if this is
the specie you have, it needs to go.>
After 2 days of swimming around happily, the 2 new Citron Gobies
both disappeared overnight...nothing, no carcass, no trace.
<Mmm, likely eaten by your scavengers and/or caught/eaten by
the Green Brittle Star if this is what you have.>
Now, to Fred.
Yesterday, the day started out well. While I was working on my
computer, all of a sudden I hear a big splash - and see my Purple
Tang flipping out of the water a good 2-3 inches, and falling
back in (there was enough splashing before this that this may
have been the 2nd jump, or he raced along the surface
first...don't know). At this point he is in his night-time
colors (very pale purple, with all the dots and stripes inherent
in his scales visible) and looks like he's hit his head - big
bare spot (white) above the center of his eyes. He's having
problems staying upright - swimming upside down, sideways, often
with his face down, fluttering his fins like he's trying to
get upright but just can't, and acts like he can't see.
He got close to where the new goby (and I assume shrimp) took up
residence (on the left underneath the Acanthastrea), so I did see
if I could prod him out of the area. He moved from there, and
took up residence IN the space inside the tall rock in the
picture...while I could move one rock from above it, it was still
hard to get to.
<Mmm, in doing this you were adding to the already present
stress of this fish.>
<<Methinks this fish "got punched" by the
Alpheid. RMF>>
My LFS guy is on vacation and didn't answer his phone, so I
did speak with several people - and based on where the tang was,
and the fact he was still pale purple, we thought he might stress
out even more if I tried to get him out of the tank into a
quarantine tank than if I left him.
<True.>
So I left him and checked on him several times throughout the
afternoon and evening. I think he died last night, based on the
fact that right before my bedtime, the Flame Angel swam above him
in the crevice and he didn't move, but wasn't sure - at
that point he hadn't completely settled in like this
morning.
This morning, I again looked, but when the Brittle Starfish was
there, I thought he was most likely dead...so I went through the
creative process of rescuing him (slim hand, middle two fingers
finally grabbed him on the 4th or so attempt) and pulled him
out.
You can see the pictures I took of him. Yesterday morning he was
a beautiful (to my eyes) healthy tang - no Ich, no HLLE, very
happy, swimming around everywhere, eating everything I could feed
him...
Then he jumped, and less than 24 hours later he's dead.
Any ideas? Is the fact that I have lost several things over the
past year or so an indication I need to do something?
<I would first determine the specie of Brittle Starfish you
have.>
I didn't think my bioload was tremendous...the powerhead on
the right is a VorTech-MP40W, and I have a 20 gallon tank
underneath as a sump (in fact, my skimmer has slowly, over the
past 6 months, gotten to where I don't even get any skimmate
- periodically just some clear water and nothing else)...it's
been set up for over year now.
The only other things I have done in the recent past are:
- slowly switch from SeaChem's Reef Salt to the Red Sea Coral
Pro salt mix (I am still doing water changes with both types of
salt,
<Any particular reason for the salt change?>
but have been doing that since Christmas), and - I have two cups
(those cups you hang off the tank when you get new fish) hanging
off the edge into the tank; they have holes drilled in them and I
am growing mangrove pods - but that was a December addition,
nothing extremely new.
As I said, I would love inputs - I haven't recently, but can
check nitrite, nitrate and ammonia levels if you thought that
might affect anything.
<Certainly. Any reading of nitrite or ammonia would not be
good.>
I haven't gotten new rocks in quite a while (last summer, I
believe), and other then fish haven't really changed
anything...any ideas? It seems to me he got stung - but what
would get him to react like that, and what can I do? Should I
have done anything differently?
<Based on the information you have provided, I would say there
was nothing that you did that caused the tang's death.
I'm thinking this fish may have been spooked and caused
damage to itself beyond healing, especially considering that this
was a very healthy fish less than 24 hours before it's death.
On the other hand, there exists the possibility of a toxin
getting into the water such as Windex, etc. and the fish panicked
in looking for a healthier environment. Did any of your other
fish display any strange behavior during this period?>
I greatly appreciate you inputs, and would love any
ideas/suggestions/even berating on my actions...I really hate
that my tang died (and the way in which he died); I enjoy my
tank, and am currently clueless what else to do.
<I would test for nitrite and ammonia thereby eliminating this
as a possible cause. You may also want to introduce a chemical
media into your system to further improve water quality. A good
grade of carbon or Chemipure would be a good choice. If you
haven't done so already, you may want to read here and
related articles/FAQs. http://www.wetwebmedia.com/z_xanthurum.htm>
Thanks in advance,

complete right after the jump.
Left side view - he had a full set of fins right after the
jump...
Front view - the white spot was originally above a line drawn
between the eyes, maybe 2 mm wide - only appeared after his
jump.

Geez Bob, I didn't think a pistol shrimp had that kind of
knock out power.
<Oh yes! Compared w/ a .22 at times... See the pic here:

My Pistol Shrimp died a while back but he was no Cassius Clay for
sure, but then the goby didn't
let anything near their cave to get punched.

Unexplained Death Of A Beautiful Tang/Zebrasoma xanthurum/Health
4/20/2011
Good morning, crew!
<Good morning to you, Kerstin.>
I haven't written in some time, but I just lost my Purple
Tang, and am at an absolute loss as to what happened, or if I did
the right thing or not.
I included some pictures in the hope someone can provide some
insight please...or at least commiserate in the loss of this
lovely fish (or even berate me for my stupidity...). I apologize
in advance for the long email.
<No problem, the more info the better.>
The first picture shows my tank from last September. It is a
92-gallon corner tank, it has been set up since November 2007, at
which time I moved my inhabitants from a 3-y.o. 29-gallon tank.
Fred, my purple tang, was originally in my 29-gallon tank, and I
knew it was too small for him, so I
knew he'd love the bigger tank; in fact he's been happy
in there for the past 3-1/2 years. His current co-inhabitants
were: <were or are?> {as you'll see below, were - since
I fished my poor tang out of the tank dead this morning}
2 Centropyge - one a Cherub face dwarf (have had over a year),
the other a one a Flame Angel (close to a year now)
1 Lemon Goby (in tank for over 6 months)
2 Clown Fish (both in tank over 6 months now)
1 Royal Gramma (who more often than not disappears for days/weeks
at a time, and always lives behind the center pile of stone
pictured below...has currently been out of sight for about 3
weeks, but that's nothing new...has been there for about 4-6
months)
1 Brittle Starfish
1 Blood Red Shrimp
about 23 corals (I no longer have either of the disc corals in
this picture).
The 6- <Six> {sorry - shortcut}
<<No problem, and always cap proper nouns as in names of
animals, products, etc.>>
Line Wrasse in this picture was caught after Christmas - I was
tired of him being the emperor and terrorizing the entire
tank.
<Not easy to catch, are they.> {you'll laugh. When we
went on vacation, one of the two clowns and the wrasse jumped
into the overflow - so when I came back and found them, I was
able to easily catch him in there without having to dismantle my
tank - that's what he got for jumping!}
<<That's what I'd call good luck.>>
Recently I had purchased a (in hindsight) too-skinny Blue Faced
Sleeper Goby, and he passed within a day. In discussion with the
LFS, we think he truly was just too skinny and beyond rescuing.
At this point, I check water values - Spec. Gravity slightly high
at 1.028, Calcium low at 196,
<Very low, this has to come up to an acceptable level.> {I
have, over the past two weeks, raised it to a much more
acceptable level...see comments on salt below}
Alkalinity high at 9.5 dkH, and Magnesium normal (in the mid
1300's I believe). {actually, mid 1400's - but still
within range, I believe}
<<Best to keep between 1200-1300. Is actually a 3 to 1
ratio. If calcium is at 400, magnesium should be near 1200. This
ratio makes it easier for calcium loving animals to absorb the
available calcium.>>
I worked at lowering my specific gravity a little. About 2 weeks
later (last week on Friday), I purchased 2 more Citron/Lemon
gobies and a matched pistol shrimp and goby...I did the research,
and thought these would work well with my tank...they were to be
my last purchases. Everything I read also indicated they did not
do well with quarantine, so I did not do that with these fish. I
spent about 5 hours acclimating them, to make sure they were used
to my tank water.
Well, strange things seem to be going on - and I am now going to
research more - but would love to have inputs - because I just
have no clue even under what terms to search for this. I did look
right after this happened, but "Fish jumped/not swimming
right just doesn't seem to work well.
As I mentioned, my Royal Gramma often disappears from sight for a
while.
However, now I am beginning to think maybe there's more to
it.
<Does the fish come out during feeding time?> {He sometimes
did, sometimes not - it really varied even before this latest
disappearance - he never came out front, he always stayed behind
the rocks, so I had to look into the right side of the tank to
look behind the rocks to see him}
Over the past year, my shrimp population has decreased from 4
cleaners, 2 blood reds, and a mated pair of Coral Banded to the
one red shrimp...thought it might just be old age, as I have had
some of them from the beginning of this tank.
<Shrimp/crustaceans do require iodine/dide dosing to help with
their molt, and depending on the specie of Brittle Star you have,
this animal could be the culprit. The Green Brittle Star of the
genus Ophiarachna is a notorious fish/shrimp eater and if this is
the specie you have, it needs to go.> {I know he's not a
green brittle star - he's a not-spiny brownish/black star
with a head of less than 1 inch in diameter - I have only ever
seen him go for dead stuff or shrimp pellets}
<<OK>>
After 2 days of swimming around happily, the 2 new Citron Gobies
both disappeared overnight...nothing, no carcass, no trace.
<Mmm, likely eaten by your scavengers and/or caught/eaten by
the Green Brittle Star if this is what you have.> {but if it
is not a Green Brittle Star (my LFS has one, mine is definitely
not it), then why would the 2 new guys disappear together...good
question?}
<<I've had similar instances happen to me with Citron
Gobies for no apparent reason, but obviously there must be a
reason.... possibly harassed/killed by a tank mate(s).
They are best kept with docile fishes and feel more at ease if
Acropora is present for security. In the wild they live amongst
Acropora and derive some of their food from the coral.
Bob may chime in here with his observations of these fish in the
wild.>><Commented/archived on WWM per the genus<
Now, to Fred.
Yesterday, the day started out well. While I was working on my
computer, all of a sudden I hear a big splash - and see my Purple
Tang flipping out of the water a good 2-3 inches, and falling
back in (there was enough splashing before this that this may
have been the 2nd jump, or he raced along the surface
first...don't know). At this point he is in his night-time
colors (very pale purple, with all the dots and stripes inherent
in his scales visible) and looks like he's hit his head - big
bare spot (white) above the center of his eyes. He's having
problems staying upright - swimming upside down, sideways, often
with his face down, fluttering his fins like he's trying to
get upright but just can't, and acts like he can't see.
He got close to where the new goby (and I assume shrimp) took up
residence (on the left underneath the Acanthastrea), so I did see
if I could prod him out of the area. He moved from there, and
took up residence IN the space inside the tall rock in the
picture...while I could move one rock from above it, it was still
hard to get to.
<Mmm, in doing this you were adding to the already present
stress of this fish.>
My LFS guy is on vacation and didn't answer his phone, so I
did speak with several people - and based on where the tang was,
and the fact he was still pale purple, we thought he might stress
out even more if I tried to get him out of the tank into a
quarantine tank than if I left him.
<True.>
So I left him and checked on him several times throughout the
afternoon and evening. I think he died last night, based on the
fact that right before my bedtime, the Flame Angel swam above him
in the crevice and he didn't move, but wasn't sure - at
that point he hadn't completely settled in like this
morning.
This morning, I again looked, but when the Brittle Starfish was
there, I thought he was most likely dead...so I went through the
creative process of rescuing him (slim hand, middle two fingers
finally grabbed him on the 4th or so attempt) and pulled him
out.
You can see the pictures I took of him. Yesterday morning he was
a beautiful (to my eyes) healthy tang - no Ich, no HLLE, very
happy, swimming around everywhere, eating everything I could feed
him...
Then he jumped, and less than 24 hours later he's dead.
Any ideas? Is the fact that I have lost several things over the
past year or so an indication I need to do something?
<I would first determine the specie of Brittle Starfish you
have.>
I didn't think my bioload was tremendous...the powerhead on
the right is a VorTech-MP40W, and I have a 20 gallon tank
underneath as a sump (in fact, my skimmer has slowly, over the
past 6 months, gotten to where I don't even get any skimmate
- periodically just some clear water and nothing
else)...it's been set up for over year now.
The only other things I have done in the recent past are:
- slowly switch from SeaChem's Reef Salt to the Red Sea Coral
Pro salt mix
(I am still doing water changes with both types of salt,
<Any particular reason for the salt change?> {I had been
using the Seachem for ages, but in the past year have been
battling various little issues, and for the past 2-3 years a low
alkalinity issue (my tank was a sink, could never get the
alkalinity to go up).
<<An imbalance in water parameters somewhere. May want to
read here.
http://www.wetwebmedia.com/alkalinity.htm>>
When my LFS started having problem getting the Seachem, I looked
at other salts, decided to try this - since doing even just a
1/2-1/2 mix, my corals have started to perk up, which may be
because the alkalinity/calcium ration was changing...don't
know...but since they look happier, I thought I would completely
switch over}
<<For what it's worth, I like/use Tropic
Marin.>>
but have been doing that since Christmas), and - I have two cups
(those cups you hang off the tank when you get new fish) hanging
off the edge into the tank; they have holes drilled in them and I
am growing mangrove pods - but that was a December addition,
nothing extremely new.
As I said, I would love inputs - I haven't recently, but can
check nitrite, nitrate and ammonia levels if you thought that
might affect anything.
<Certainly. Any reading of nitrite or ammonia would not be
good.>
I haven't gotten new rocks in quite a while (last summer, I
believe), and other then fish haven't really changed
anything...any ideas? It seems to me he got stung - but what
would get him to react like that, and what can I do? Should I
have done anything differently?
<Based on the information you have provided, I would say there
was nothing that you did that caused the tang's death.
I'm thinking this fish may have been spooked and caused
damage to itself beyond healing, especially considering that this
was a very healthy fish less than 24 hours before it's death.
On the other hand, there exists the possibility of a toxin
getting into the water such as Windex, etc. and the fish panicked
in looking for a healthier environment. Did any of your other
fish display any strange behavior during this period?> {no
toxins - don't use them in this room at all. Also, none of
the other fish looked or acted differently at all - just the
tang}
<<OK. Sure sounds like Bob's suggestion on the Pistol
Shrimp may hold true.>>
I greatly appreciate you inputs, and would love any
ideas/suggestions/even berating on my actions...I really hate
that my tang died (and the way in which he died); I enjoy my
tank, and am currently clueless what else to do.
<I would test for nitrite and ammonia thereby eliminating this
as a possible cause. You may also want to introduce a chemical
media into your system to further improve water quality. A good
grade of carbon or Chemipure would be a good choice. If you
haven't done so already, you may want to read here and
related articles/FAQs.

Thanks in advance,
<You're welcome. James (Salty Dog)>
{thanks again - I really like my tank, and while sad about the
loss about my tang, am now going to see which direction to
go...maybe it's really time to investigate the seagrass I
have thought about planting...or not.
<<May want to read here before starting this venture.
http://www.wetwebmedia.com/ca/volume_3/cav3i3/seagrasses/seagrasses.htm>>
I will check nitrates, nitrites, and ammonia in the morning (late
now after a long day on the road), and I really appreciate your
input.

Re: Question - unexplained death of a beautiful tang,
link/video on Alpheids
4/21/11
It's interesting - I always research my fish before I get
them - I don't know why I didn't think to research the
pistol shrimp, and so never thought he could be so dangerous.
<Yes>
Cool link - absolutely amazing video link about the pistol shrimp
and its "blast" located at
http://www.aquaristsonline.com/blog/livestock/invertebrates/the-pistol-shrimp/
<Interesting... "setting"; very effective message,
explanation>
So should I now worry about the rest of my livestock? I can't
decide, based on what I have been reading...if I needed to, I am
willing to catch the pistol shrimp and return him to the LFS to
safeguard the rest of my fish, but then again, it also sounds
like the tang was just a "freak" (if you want to call
it that) accident when he got to close to where the shrimp is
staying (if you look in the original tank picture, he lives under
the Acanthastrea at the bottom left of the tank).
<Mmm, "not so much" to worry re the other non-shrimp
livestock. Most are well-aware of what an Alpheid can do, will
avoid it>
Thanks again for all your inputs,
Kerstin:-)

Pistol shrimp, incomp.
11/15/10
After reading many of your comments/observations about pistol shrimp, I
would like to add a couple to your list.
<Okay>
It appears pistol shrimp can be quite aggressive on snails and hermit
crabs.
<Oh yes. Have witnessed them killing, eating these>
I have watched a pistol shrimp (about 1 1/2") drag a 1/2"
hermit crab back to its burrow and repeatedly snap at the opening until
the shell broke open.
It then proceeded to pull the hermit crab out (killed it) and take it
into its burrow. I have also seen similar evidence on different species
of snails. The type of pistol is in the Alpheus genera common in
Florida.
<Thank you for this input. Bob Fenner>
Pistol Shrimp, Callionymid comp.
5/24/10
Ok I have a 75 gal that's just about done with the cycling phase.
I've been researching and planning constantly for this tank. I have
a 30 gallon setup now and will be moving things over to the new tank.
The question I have is
I will be moving over a mandarin goby from my old tank (I know it is
actually a Dragonette) will I be ok adding a yellow watchman
goby/shrimp pair?
<Mmm, maybe... Alpheids can/do damage
Mandarins/Dragonettes/Psychedelic Gobies often...>
I know they look similar and sometimes that causes a problem in marine
fish. Just want to make sure I'm ok here with the addition.
Thank You

Red Snapping Pistol Shrimp: Alpheid Systems
4/10/2010
Hello Crew,
<Hi Matt.>
I am curious to know your thoughts on whether a Red Snapping Pistol
shrimp poses any real danger in my display reef.
<They can be somewhat aggressive, but otherwise, they are
fine.>
It is made of 1/2" glass all around, are they likely to pose any
real threat in regards to shattering the glass?
<Hmm.. I think you are confusing Pistol Shrimp with a Mantis Shrimp.
<<Actually, not. But not likely to break 1/2" plate.
RMF>>

http://www.wetwebmedia.com/marine/inverts/arthropoda/stomatopods/mantisshrimp.htm>
Should I bait and capture him out? He managed to hitchhike on the live
rock during aquascaping...discovered him recently coming out for
feeding.
<Cool.>
Also have 2 cleaner shrimp in there, I saw a gnarly video on YouTube of
a pistol shrimp making a blow on a cleaner shrimp knocking him dead in
a millisecond. Your thoughts appreciated.
<I would leave things be for now - Consider removing the pistol
shrimp if he causes problems.>
Thanks,
Matt

Sick Watchman Goby... Injured by an
Alpheid? 3/11/10
Hi Guys!
Sad say over here. I have a sick yellow watchman goby. I am
wondering if I have a bacterial infection?
<My gosh; this fish is virtually decomposing>
Here is a picture, and what he looked like a week ago.
Tank parameters are:
30 gallon tank
3-4" sand (sloped)
40 pounds LR
Warner Marine H1 skimmer
Circulation is ~ 20x
Ammonia: 0
Nitrite: 0
Nitrate:0
dKH: 9
pH: 8.2-8.3
Temp. 78*
SG 1.025
Inhabitants:
2 Yellow Watchman Gobies, Cryptocentrus cinctus (pair)
1 Tiger pistol shrimp, Alpheus bellulus
<Maybe the beginning of the trouble here... from a physical
trauma>
6 assorted hermits
Tank was finished cycling about a month ago. The gobies have been
in it about 3 weeks.
<Too soon>
I haven't seen them much, which is in my experience, quite
common with yellow watchman. In my 90, the yellow watchman was a
no show for 11 weeks after he was introduced. Haven't seen
much of the shrimp, but the sand is getting excavated constantly
so I am sure he is there.
<And may well have "punched" the one Cryptocentrus
in the face>
I haven't been that worried about not seeing them. I have
been feeding and doing water changed every week, about 4 gallons,
RO/DI water mixed for a week. The fish were fine a couple of days
ago. The other goby is absolutely fine. Saw her (?) today.
The sick one I assume is the male, being smaller/more slender.
Can you advise me - anything I can do?
<Not at this point... other than hope. I would not add any
other bottom fishes here. Bob Fenner>
Thanks
Dean

Re: re: Sick Watchman Goby
3/11/10
Thanks Bob,
<Welcome Dean>
I should have said that the LR in the tank is all mature; sitting
in tanks for at least a year. So it was walked across the room; no
shipping or die off to worry about or deal with. The sand was
seeded from my seagrass tank.
This is not the classic startup scenario.
As far as adding fish, no more bottom fish planned at all. Nothing
for six months was the plan; except for snails.
Thanks again.

injury will heal. BobF> |
Goby Compatibility/Stocking Level/Now Pistol Shrimp
Compatibility 1/11/10
What if I added another candy pistol shrimp, do you think the one I
have would fight with the new one?
<Shouldn't, the Randall's Pistol Shrimp (Alpheus randalli)
is rather peaceful toward other invertebrates.
Just ensure you have enough sand/gravel for the shrimp to burrow in.

go on blitzkriegs against each other.

territorial... I want to state this differing conservative opinion as
"insurance" against the cases where folks will have trouble
mixing them.

Pistol Shrimp/Trapping 1/6/10
Hi there just a little concern.
<OK Dirk>
I have a 165Gl reef tank
I have added some Coral Banded Shrimp lately but they disappeared quit
fast so I had to start looking what might have eaten them as I only
have Clown fish and some Tangs in there. I found out I had a Pistol
Shrimp which I believe was the cause of the strange noises I heard in
my tank and what declared the high mountains of that I kept finding
across my rocks. Anyway last week I made a big effort and took out all
my rock work and disposed of the pistol shrimp. Didn't kill it but
gave it to my local fish store.
Nice you would say only to my horror I wasn't finished yet for more
then 10 minutes and I heard the oh so familiar clicking noise again.
Now 2 days later my greatest came through and I have another
one!!!!
Again the familiar mountains of sand across my rock work.
Anyway, I am not in the mood again to re-structure my entire tank again
as who might know how many I have now?
The question now is there a natural predator of the pistol shrimp that
I could add to get rid of them?
<Most triggerfish would go after them, but I'm afraid you would
have a bigger mess from them trying to dig the shrimp out. I'd try
a trap, most folks have luck with these. Look here as to give you an
idea what they are.
http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+18180+14699&pcatid=14699>
Would love to add some more shrimp, cleaners and harlequin to my tank
but as long as this or those pistols are there this is out of the
question I guess right?
<Yes, they will always be at risk. An interesting video re Pistol
Shrimp on the following link that you may or may not enjoy:) Just
scroll down on the link to view.
http://www.aquaristsonline.com/blog/livestock/invertebrates/the-pistol-shrimp/>
Help needed.
<Try the trap, bait with a small piece of fish, crab, shrimp, etc.
and place near the burrow in the evening (lights out) when they are the
most active.

Question about placing Cleaner Shrimp in tank with
Pistol Shrimp 11/26/09
hi WWM,
I have been looking to add a cleaner shrimp to my tank in the near
future, but I am concerned about the pistol shrimp in the tank.
<Mmm, the "players" here are very often aware of what each
other are... and if there's sufficient space, habitat, can/do get
along in most cases>
I saw on the site that there can be territory problems, but the pistol
shrimp, who has been in my tank since i first set it up 3 years ago, is
rarely seen (i catch a glimpse of him once or twice a month), and I am
not
quite sure how big he is. If the pistol shrimp is half the size of the
cleaner, will it reduce tension between the two?
<Not really much of a relative size issue here. Alpheids pack a huge
punch for their diminutive proportions>
The pistol shrimp is not very big, about 1.5 inches at most when i last
saw him during the summer.
<Depending on the species, this is quite a large one... can deliver
a "shot" equated with a .22 caliber bullet!>
As for my tank, it is not very large, only 40 gallons, with about 45
pounds of Live rock, and 2 inhabitants of a Clownfish and Dwarf
Angelfish (cherub angel) who have been in the tank for sometime over
two years.
Thanks.

<I do give you very good odds of all getting along here, and making
for a much more interesting display! Bob Fenner>
Killer Pistol Shrimp?? 10/5/09
Hi guys!
<Hey Samantha! JustinN here tonight!>
I've had a 28g nanocube for quite some time now. So far everything
has been doing well and even my coral is flourishing. However,
yesterday I found one of my blue legged hermit crabs out of it's
shell with a few legs missing and very close to death.
<Uh oh..>
I figured there was nothing I could do for him and my other hermits
would eat him so I just left his body in there.
<Likely an accurate assessment, but its still better to remove
rotting/dying bits -- less potential to foul your water.>
Today I found my large coral banded shrimp also in pieces.
<sorry to hear this.>
The tank has 2 damsels, 1 yellow watchman goby, 1 yellow face Jawfish,
1 Halloween urchin, 2 emerald crabs (1 large, 1 small), 10 snails of
different species, now 7 blue legged hermit crabs, my now lack of 1
large coral banded shrimp, & quite a few different types of
coral.
<Relatively well stocked for the size -- I assume you have a proper
deep sandbed to support the Jawfish?>
I've also seen 2 bristle worms in the rocks in the past week.
<Typical, usually a sign of good tank health more than a
concern.>
ALSO - When I bought my live rock I found a very tiny shrimp in one of
the rocks. At the time he was only a half inch long and hard to
identify. That was a few months ago. Since then I've only seen him
1 other time. He's now much larger and a lot easier to identify.
I've done hours of research and looked at many images and
information on all kinds of shrimp. The only thing that it looks like
it could be is a green pistol shrimp. Though he's in the living
room which is the main room of the house and there's constant noise
and so far I haven't heard any clicking sounds that I know of.
<Mmmm... are you certain that its not a small Mantis Shrimp? See
here:
http://wetwebmedia.com/marine/inverts/arthropoda/stomatopods/mantisshrimp.htm
and related links at the top...>
He's made himself some very intricate tunnels under my main base
rock. I got the yellow watchman goby hoping they would pair up, but it
never happened. He's minded his own business for the most part. My
boyfriend has taken over the feeding and hasn't been target feeding
him for the last week. My question is do you think it's the pistol
shrimp or could it be something else we have in the tank?
<If the shrimp is genuinely a pistol shrimp, not likely -- if its a
Mantis, this would be different...>
If it is the pistol shrimp I would really like to get him out of the
tank because the coral banded shrimp was one of my favorite things in
the tank because of how large he was. If you think it was him what is
the best way to get him out of there without having to take out all the
live rock and disturbing our Jawfish, goby, and coral that have already
made their homes on, in, or under these rocks?
<Sorry to say, there's precious few other options here, if
removal is the goal...>
Please help soon. I really don't want to lose any more of my
precious animals. I have a sensitive heart and it's killing me to
see these little guys being killed off by something I didn't even
want in my tank to begin with.
Thanks so much!
Samantha
<Do read through the above link and its related FAQ's -- sounds
more like a predator shrimp than a pistol to me. Let us know if you
have further questions! -JustinN>
Re: Killer Pistol Shrimp??
An update on the situation - last night we were trying to get the
shrimp to come out from under the rock. It took a lot of time and
effort, but he finally came out enough to see him closely again.
<Excellent>
However, he wasn't out long enough to capture.
<Too bad -- they are elusive though.>
I'm 100% sure he isn't a mantis shrimp. He looks identical to a
video of a green pistol shrimp I saw on YouTube.
<Excellent -- mantis shrimp are definitely relatively defined in
appearance -- if you got a clear look, you're probably ok.>
He sort of looks like a tiny lobster which to me is what the pistol
shrimp looks like too. We also finally left the top of the tank open
long enough to hear him clicking. It's loud enough to hear over the
TV. It's a loud crack once every 10 min.s. or so.
<Sounds about right.>
Also, when we were trying to push him out from under his rock we heard
the cracking quite a few times. He also grabbed onto what we were
trying to use to push him out with. We're almost positive it is
a
pistol shrimp in there, but if he isn't the one killing off the
other animals we don't want to bother him.
<I'm doubting it.>
However, if he is the killer I'm willing to go to extreme measures
of removing all the live rock in order to remove him from the tank. The
only reason why I really think he's the one who killed the other
animals is because when we found the coral banded shrimp his body was
directly in front of where we got the pistol shrimp to come out.
<Likely coincidental>
So far, all of our other animals have gotten along just fine in the
tank, but if you think it might have been one of them I'm willing
to hold off on removing the shrimp long enough to see if any of the
other animals seem to be getting territorial. However, if you do think
it's the pistol shrimp I'd like to get him out as soon as
possible.
<I don't think a pistol shrimp would be causing this sort of
chaos, personally. Perhaps a water chemistry issue, such as high
nitrates/nitrites, or a lack of needed iodine... Do some water quality
tests -- more than your basic set of
PH/Ammonia/Nitrate/Nitrite...>
I hate seeing my other animals being killed off as I do have them all
named and they have become part
of our large animal family. Any help is very much appreciated! I'm
very grateful for the service you guys provide us loving, curious, and
sometimes confused aquarists.
Samantha
<I think you're pretty safe from the pistol shrimp, Samantha.
I'd begin to looking towards other environmental factors -- do
remember, all it takes is a creature to pass away for the tank's
'never-seen-in-the-light-of-day' cleaning crew to start their
scavenging -- the remnants you saw could be related to this.

Pistol or mantis hitchhikers: Hard to tell, but best
guess is a pistol.. Hitchhiker\Pistol Shrimp\Mantis Shrimp
8/23/2009
Hi team,
<Hi Kevin.>
I'm finally restarting a SW tank after the first one was destroyed
by hurricane Ike. Four weeks without power is apparently bad for SW
tanks... sigh.
My new tank has been setup for 6 weeks or so. It's a 44g pentagonal
with a 96W PC fixture, an Aquaclear 70 HOB filter (sponge and ceramic
bio pieces only), a Koralia 1 and a Maxi 900 with a sponge filter on
it. I started cycling it 3 weeks ago and had 40 pounds of dead rock. I
added about 10 pounds of 'fully cured' liverock and about 30
pounds of live sand. Tank was cycled in two weeks. Last weekend I added
a torch coral and a small rock covered in green star polyps. I got a
pair of mushrooms as hitchhikers on another rock and some clove polyps
on yet another rock.
<Everything sounds good so far.>
So that was 3 weeks ago. Yesterday, my wife mentions that she's
hearing clicking sounds from the tank. Finally tonight, I heard them
too. They are pretty loud, but seem to be single pops. However, the
rock that's in the back of the tank seems to have a lot of
'debris' around it... like silt or something. It could be just
that, that the flow of water has cleaned the rock of debris (and I have
it in a different position that the tank I got it from).
<Possible Mantis and Pistol shrimp are diggers too.>
The tank I got this live rock from is a LFS's cured live rock
tank.
There is nothing in that tank but live rock.
<As far as anyone knows.....>
I have dealt with the misery of mantis hunting before and did not enjoy
it. I guess the question is would a mantis or pistol shrimp, not do
anything for almost 3 weeks and then start popping?
<Very possible.>
I know they are crustaceans, but can they go 3 weeks without food.
There is no mobile life in the tank except for some tiny worms and some
very, very tiny blue starfish.
<That is what is making me lean towards a Pistol Shrimp. You can put
a few crabs in the tank as a test. If it is a mantis, it will come out
after the crabs.>
I was thinking of adding a pair of clowns this weekend, but I don't
want to if I have to go mantis hunting.
<Put a few crabs in the tank and see what happens. To look at it
another way, Mantis Shrimps by themselves do make for an interesting
display.>
It's just weird that nothing happened for almost 3 weeks, then
pops.
Thanks for any info you have.

Pistol shrimp and Coral banded shrimp,
incomp. 6/21/09
Hello,
<I say a greeting>
I have intermediate reef experience. I have a new 34 gallon tank, 1.5
lbs/gallon live rock, established tank (3+ months), all chemicals in
spec for a reef tank, 17 snails, 7 hermits,
<Mmm, too many of both>
2 feather dusters, 1 coco worm, 1 clam (crocea) and 1 coral banded
shrimp.
I want to get a pistol shrimp and yellow watchmen goby which I've
never had before; my question is will the CBS attack the pistol shrimp
or vise versa.
<Yes>
I feed the CBS regularly and appears timid, although he has only been
in the tank for 2 weeks.
<Are predaceous... will likely begin to consume your snails and
anomurans...>
The other fish I want for the tank, eventually, is a mandarin goby and
a six line wrasse ( I will be providing extra copepods to supplement
the mandarin since I've heard the wrasse will out compete the
mandarin for food).
<Can>
Thanks,
Tom

Pistol shrimp compatibility -- 03/02/09 Hi!
First of all, sorry for my French-influenced English... Second thing,
thanks a lot for the help and advices you've been giving so far
(not only to me, but to all the community)! Now with my question. I
have a Pistol Shrimp that's been in my 65g for a little more than 2
years now. He (or she) is a healthy little guy (or gal... never asked
him ;) ) that seems to have established his territory from one side to
the other of the tank. It never caused any trouble, at least that's
what I was thinking until I found out what was killing my Cleaner
shrimps. (thanks to YouTube...) I was wondering if there are any
parasite eating/cleaning shrimps that could possibly be compatible with
my Pistol? I've seen the pistol cleaning my Yellow tang once, but
as far as I know, Pistols are not known to be cleaners... I also have
another question: 65g + 1 Flame Angel + 1 Yellow Tang + 1 Orangespotted
Goby + snails, hermits, urchin, pistol s. = is it too loaded? Would it
be a risky game to add a dwarf lionfish? Merci beaucoup for your help!
<Hello Ivan. Do see here: http://www.wetwebmedia.com/alphcompf.htm
From personal experience I'd say "it depends". Do bear in
mind Alpheidae are all predatory to some degree, and will view smaller
invertebrates as prey. The species I maintained under lab conditions
(coldwater species from California) were incredibly hardy and held
their own very well with crabs of equal size. While I dare say
they'll mix fine with somewhat larger, fast-moving midwater fish, I
wouldn't personally recommend combining them with anything small or
slow. As for your 65 gallon system, assuming water quality is
acceptable, it doesn't sound overstocked to me. But I wouldn't
recommend adding anything else. Cheers, Neale.>
Snowflake and shrimp, incomp. 12/17/08
9 months ago I noticed something moving in my live rock, I have a 17
gallon Marin tank with one Snowflake eel and some grass shrimps.
<Too small a tank, even for this eel.> Today I found out what was
the little thing moving inside the tiny holes of the rock, it was a 1
inch long pistol shrimp, he's green and tiny and didn't mind
taking out his head and horrible arm to grab everything he can find
around the rock. Is he dangerous for the grass shrimps??? <Can be,
but your eel is too, will eventually eliminate them anyhow.> or the
eel??? <The eel is a threat to the shrimp.> If so, what can I do
to take him out???? <In a system this size I would simply tear it
apart and remove him if you feel you need to. In time the eel will take
care of the shrimp!> Thanks, and sorry for the English mistakes!!!
<No problem, it is obvious to us those who are not native English
speaker vs. those who are just lazy! Welcome, Scott V.>
Alpheid sp. compatibility question.
11/17/08 Good Morning. <Buenos tardes> I have a quick
question regarding a Pistol shrimp. The LFS has what they are calling a
Blue-legged Pistol shrimp. I have done some research, but I'm
getting mixed opinions as to compatibility with fish. <Mmm, a few
general statements re Alpheid/fish compatibility... these shrimp will
consume, paralyze smaller to good-sized fishes if... hungry,
threatened, crowded... but many individuals do learn to/get along over
time, with familiarization... Is this an Alpheus immaculatus? An
"anemone" pistol shrimp? This species is reported to be
non-fish friendly... likely keeping such out/away from their symbiotic
Bartholomea hosts...> Right now I have 3 B-G Chromis, 2 Fire fish
and 1 Yellow watchman Goby in a 75 gallon tank (80 lbs L Rock, 2
frogspawn frags, 1 hammer frag, 2 small zoos frags) . I would like to
attempt to "match" the Goby with a Pistol shrimp (I know it
is a crap-shoot). <Yes> Regarding the "Blue-legged"
Pistol shrimp, I've read extremes about it; from they are very
compatible and can form a symbiotic relationship with Gobies to they
are not compatible and will kill anything that gets in/ near it's
burrow including Gobies. <Again... you/we need to ascertain the
species here...> I've read all the great WWM info about Pistol
shrimps in general but could not find anything about this specific
Pistol shrimp. Any information would be appreciated before purchasing
this shrimp and playing Russian roulette with the shrimp/Goby. Thank
you for any information you may provide, Miguel <Please see the
Net/pix re... is this Alpheus immaculatus? Bob Fenner>
Alpheid sp. compatibility question, pt.2
11/18/08 Thank you for the reply Bob. Somehow your answer did
not get to me via e-mail, but I did see it in the "daily
questions" section. <Mmm... as always, am wondering why the
message/s don't go directly... every time> I did a search under
Alpheus immaculatus as you suggested and it does appear to be what the
LFS is selling as the "Blue-legged" Pistol Shrimp. Now that I
know what it is, I'll do some more research. What I'm seeing so
far is that it is not that common a shrimp and not much
"captive" information is known. Miguel <Ahh, and as
hinted, the Alpheids that don't directly have symbiotic relations
with fishes themselves, are often VERY antagonistic toward them... i.e.
they exclude ("with extreme prejudice") would be predators on
their anemones, crinoids... Bob Fenner>
Pistol Shrimp and Goby... sys., comp. --
09/08/08 Thank you folks so much for your website. I can
usually find an answer to my questions by browsing through your
extensive "library" of information. However, I haven't
seen this one! I bought a pistol shrimp (very small, about 1/2")
for my Randall's Goby and they hit it off right away. The shrimp
dug out a burrow in the four to five inches of fine sand I have in a
28g aquarium. The Goby moved in but then I actually observed the shrimp
pinch the Goby on the lip. <Yow!> Then I noticed the tail fin of
the Goby shredded. <Ooooh, trouble in paradise> The Goby seemed
to stay away from the burrow for a while and it caved in. I thought the
pistol shrimp expired. The shrimp showed up about three weeks later in
another burrow and was now about 3/4" in size! The Goby seemed to
"forgive" him for the rough behavior and moved in to the new
burrow. One day I saw my Red Firefish backed into the same burrow.
<Mmm, Microdesmids really need more room than this... and this is a
social/paired species> I then noticed the tail fins on the Red
Firefish were "trimmed" a bit. Then the Goby's tail fins
suffered the same fate once again. Again, a cave-in of the burrow and
the Pistol has not been seen in over a month. However, the Goby has
taken to reside near the back of the tank <No place else to get
away> and he was almost missing his entire tail last week but, doing
fine health-wise if you don't count the exertion it takes for him
to swim quickly! I am wondering if I should be feeding the Pistol
Shrimp something specific so he doesn't "pick" at the
Goby? <I would try, yes...> I feed a frozen commercial reef fish
food that includes fish meat and vegetation, pellets, brine shrimp
occasionally and just started feeding mysis shrimp after reading your
articles. Do Pistol Shrimp lay dormant or hibernate for a period of
time? <Mmm, do become cyclically "slow" during
molts/ecdysis periods> If the "cave-in" occurs from the
fine sand, can the shrimp dig its way out or can it suffocate?
<Should be able to dig out... but I would mix in some larger rubble
material... in at least part of the bottom here... that these animals
will incorporate...> Should I add a more coarse substrate to an area
of the tank to facilitate some type of habitat/food source? <Ah,
yes> If the tank did reach 83-84 degrees a time or two this summer
could it have killed the shrimp since we have not seen him? <Mmm,
doubtful> I hope the Pistol is still alive but, my girlfriend
isn't happy that he beats-up the Goby that is one of her favorites!
<These animals really need to either be placed in a much larger
(let's say a minimum of four foot long) system or separated
period> Thanks for any help for me and maybe a few of your other
readers with similar questions. Gary Yorba Linda, CA <Welcome. Bob
Fenner>
Goby And Pistol Shrimp Pairing 2/19/08 Hello WWM Crew!
<Hi Mike> First let me mention how much I appreciate the time and
effort you all give in order to provide one of the best marine
information resources on the web. <Thank you.> The reason I am
emailing you today is I have recently been offered a small, one inch
pistol shrimp that hitchhiked into a friend's tank by way of his
Caribbean live rock. I volunteered to adopt this pistol shrimp in hopes
of the shrimp pairing up with my small Valenciennea puellaris goby,
which is approximately 2.5 - 3 inches in size. Here's where my
questions begin: The health and well being of my goby is of the utmost
importance, as his crazy antics and silly personality have made him
like family to me. Is there a reasonable chance that the Pistol Shrimp
could harm him? <No.><<Mmmm, actually... these animals
being from disparate seas, this is a very real possibility. RMF>>
I've searched online and haven't seen any indication that it
might attack a goby, but I rather be safe than sorry. Also, what are
the chances of this goby pairing up with a Caribbean pistol shrimp? If
I remember right V. puellaris is an Indo-Pacific goby. <Yes, and the
Coral Sea and Sri Lanka. I'm thinking the pairing up would be slim,
but you never know. Pistol shrimp generally pair up with Amblyeleotris
or Stonogobiops Gobies.> Thank you so much for everything you do and
I appreciate any information you can provide me. <You're
welcome. James (Salty Dog)> Best Regards, Mike Didn't think a
Pistol Shrimp would harm a goby that size. Regards, James <These
Alpheids can pack a real punch... enough to really damage even a human
hand. B> Yes, I do have one (Alpheus bisincisus) that is
paired up with a Yellow Watchman Goby. I can tell when something
is disturbing him has you can hear the clicks throughout the house, but
has not harmed any fish or other inverts in the two years I've
had. Jim
<Ahhh!>
Shrimp Compatibility 1/18/08 I hear of
Pistol Shrimp eating Cleaner Shrimps. Will they eat Sexy Shrimp as
well? <The Pistol Shrimp is relatively safe with most
invertebrates, but with small shrimp such as the Sexy Shrimp...I
would not chance.> Thanks, <You're welcome. James (Salty
Dog)> Carol
Jawfish/Goby and pistol shrimp combo
01/09/2008 Hey guys and gals how are things? <<Hello,
Andrew here>> I have a couple questions this morning. I've
been doing a lot of research regarding Jawfish, and also have a love
for the shrimp/goby relationship. The FAQ's have provided me
great knowledge regarding these animals.<<Great to hear>>
But, I still have a couple questions. I've been playing with
marine aquariums for over five years now, and have set up three of
four tanks due to moving and travel. Unfortunately, until now I had
no idea that the rockwork is better placed on the glass rather than
the substrate. <<A lesson well learned>> My tank has been
sitting for about 2 months with no fish, it's 40 gallons with
50ish lbs of live rock. (1/2 of which is either touching bottom glass
or very close to it from digging liverock into substrate) I also have
Goniopora, Button polyps, green star polyps, and mushrooms. I have
created a 6"-7" DSB about 9" square away from the
liverock for the Jawfish to build his den, sand bed is about 2"
elsewhere. Now for the questions. With this setup will a Jawfish
build his den in the desired location? <<Stands a good chance,
nothing is certain though>> If not will it put my rock
structure in danger of shifting and damaging my tank? <<If the
fish digs under rock which is only supported by sand, then
yes>> If so, would the pistol shrimp/ goby combo be a better
fit? <<The pistol will dig just the same as the Jawfish>>
Lastly, if both the Jawfish and pistol/goby are o.k. in my conditions
would it be at all possible for me to have both? <<Yes, given
good tank size and big enough deep sand, should be fine>>
Thanks again for everything you provide, any help as always is
greatly appreciated. Steve <<Thanks for the questions, A
Nixon>>
Re: Jawfish/Goby and pistol shrimp combo
01/09/2008 Thanks for the quick response Andrew, greatly
appreciated. <<No problem>> If I dig under the liverock
so it will be in direct contact with the bottom of the tank will the
concern about the Jawfish and goby/pistol be laid to rest?
<<Yes, that will be better>> thanks again, Steve
<<Thanks, A Nixon>> Pistol shrimp/gobies in new
tank Hello, I am in the process in setting up my reef tank (75
gallon). I have 100 pounds of live rock and 25 pounds of lace rock. I
am wondering if I can add two pistol shrimp and a wheeler watchman
goby and a Randall prawn goby (or should I just stick with one pair
pistol/goby combination) with the following list of wants of
livestock. want to add (over a period of time) 2 fire shrimp 2
cleaner shrimp 1 banded coral shrimp emerald crab (x2) 2 Percula
clowns (w/anemone and anemone crab inside) 2 sand sifting stars sally
lightfoot crab 4 green Chromis 50 bumble bee snails various red/blue

miracle wet/dry (Rio 2500 pump 720 gph) two Fluval 404's Berlin
xl turbo skimmer 4 VHO 110 watt lights aragonite sand (75 pounds or
so) what needs added for the goby/pistol relationship to work. Thank
you for you time and consideration. its hard to find good advice when
starting out your new aquariums and ideas for livestock Jeff
Morningstar <Mmm, the fishes you list and the non-crustaceans
should pose no problems... but the other shrimps... might be consumed
by or consume the Alpheids if hungry... I would start/do what you
propose... go with just the one pair first (either), and see how they
fare. If it were me/my system, I would acclimate the new mutuals in
an all plastic specimen box (like the ones used for housing small
amphibians, lizards, bugs... available at pet shops) on the bottom
for a few days ahead of releasing them. Bob Fenner>
Pistol Shrimp Bob, When I set up my reef
tank 15 months ago, one of the critters included with "the
Package" from Tampa Bay Saltwater was a pistol shrimp.
Since then, and the tank is going well, I have been reading
about the horrors of mantis shrimp. How can one determine if
one has a pistol shrimp or a mantis shrimp? Both make that
snapping sound and both hide pretty well. I understand that the
pistol should be OK in a reef tank and the mantis not. Or are
both dangerous to hermit crabs and snails? I have noticed that
I need to replace my hermit crabs and snails every so often.
<Mantis are dorso-ventrally compressed, and have longer bodies,
with prominent eyestalks... Pistol Shrimps are more laterally
compressed, not very large and have one longer, cylindrical claw...
very different appearing. Both can/will eat hermits and snails>
Finally, if I'm better off without the pistol, how do I get
rid of it? It has grown some since I set up the tank. By the
way, I use the Berlin system which seems to be working well. I
also have a banded coral shrimp and a cleaner shrimp. Possible
culprits in the disappearing snails and crabs?
Thanks, Jim >> <Best to bait out these animals with
something meaty on a stout string/line... toward night time, or use a
"live rodent trap" made of plastic (sold at large hardware
stores)... and Yes, if hungry enough cleaners, including Stenopus
will eat snails, hermits. Bob Fenner>
- Hungry, Hungry Pistol Shrimp - <Greetings,
JasonC here...> Ok, so my Pistol Shrimp is feasting on my hermit
crabs... I would like to have crabs and keep my Pistol
Shrimp. I noticed some bright red crabs at an aquarium
today. The looked like bright red peppers on
legs. I think the pet store had them labeled as Halloween
Crabs??? I don't know what they were, couldn't
find them in your listing. Any idea of what they were?
<Not really, this name 'Halloween crabs' is used on
several types of crabs that I have seen... and they're not all
the same. Perhaps ask the people at that store if they have the Latin
name for those crabs.> They are larger than my hermit crabs but
smaller than my emerald crabs. Where the emerald crabs are
flat bodied... these were 'pepper' shaped?? Any
idea what these are? <Nope.> I think that being a bit larger
that perhaps my Pistol Shrimp wouldn't attack them? <I
don't think so, your Alpheid [snapping shrimp] has superior
firepower, if you know what I mean.> If I bought a few of these
and let my remaining hermit crabs become lunch... would that do the
trick?? <I don't think so.> What are your thoughts??
<Your best bet is to offer the shrimp some food directly, perhaps
frozen shrimp or other meaty food. If it is satiated, then perhaps it
will be less likely to look elsewhere for food.> Would these new
red crabs conflict with my emerald crabs or coral banded shrimp?
<Hard to predict. I don't really trust any crab much farther
than I can throw it.> Dave <Cheers, J -- >
Pistol Shrimp is having $1.75 lunches... Simple
question... I've had plenty of small blue-legged
hermit crabs and a Pistol Shrimp for close to 3 months
now. Just over the last week have caught my Pistol Shrimp
on 4 occasions snatching a small hermit crab and pulling him under a
rock into his cave. Is this normal? <Not unusual> Is
he eating them? - dumb question? What do Pistol
Shrimps usually eat? Is there something I can do to stop
this? Dave <They (Alpheids) consume most meaty items. Either
removing it/them or their food is prudent. Bob Fenner>
Pistol Shrimp & Gobies Pairs How are you guys
doing? <Very well!> Fine I hope. How aggressive are pistol
shrimp? <Mine only bother someone who tries to hide in their
burrow.> Looking to buy a goby/shrimp combo but I don't want
him eating more expensive dinners than I do.
<Given enough room and hiding spots, they are pretty peaceful,
keeping to themselves, but mine have killed about a half dozen
animals over the course of the four years I have had them. Two
Cleaner Shrimp right after they were introduced darted down into the
Pistol Shrimps' home. Snap, snap, snap, I never saw the Cleaners
again. Also, a few small fishes when I have been rearranging rock or
adding corals, basically disturbing things. The fish got scared and
tried to hide on the other end of the tank. Note, that my shrimp do
not have a Goby living with them. Perhaps the Goby would have
prevented the other fish from entering the cave. -Steven
Pro>
Moose & Squirrel? Nope, Goby & Shrimp...
(04/18/03) Thank you in advance for any assistance you might
provide.... <Ananda the goby-fan here tonight...> I am looking
for a scientific name of a partner goby that I have in my
tank. <Detective work is fun...!> It was called a
"Yasser Haji" goby.... who knows if the spelling is good or
even accurate. <Well, Mr. Arafat would agree with the
spelling of Yasser, and others might like the spelling of Haji, but
the gobies sure don't know why they're saddled with such a
name... nor do I. So far, Google searches on any combination of
"Yasser", "Haji", and "goby" are
turning up nothing.> He appears to be very similar to a
Stonogobiops nematodes, although he has horizontal red stripes on a
white background with a mottled red and white face. He has
the same filamentous fin. It appears to extend almost as
long as his body, which is less than 2" long. He also
has a yellowish tail fin. <Ah, now we're getting
somewhere. In Scott Michael's book "Marine Fishes", the
Stonogobiops nematodes is on p. 355. Flipping the page, I see what I
think is your fish, listed as "Stonogobiops sp." on p. 356.
The "sp." designation means it hadn't been given a
species designation yet. But Fishbase.org has a handy search feature.
A search on the genus "Stonogobiops" shows two interesting
entries: "Stonogobiops sp.", and "Stonogobiops
yasha". More interestingly, the latter is considered the correct
name for the former. The detailed entry page has no photo, but the
description fits. A quick check of the remaining Stonogobiops
listings, and I'm fairly certain that S. yasha is the fish. The
species name was given in 2001, after the book Marine Fishes was
written, so that fits, too.> I had his partner too but it has
apparently died during a molt. It was a brilliant red and
white also and had the characteristics of a mantis shrimp,
approximately 1" long. <Fishbase lists Alpheus randalli as
this fish's shrimp partner. A quick Google search on
"Alpheus randalli" turns up web pages with photos of both
the shrimp *and* the goby! And a couple of pages show the goby
clearly labeled as Stonogobiops yasha. (I must make one clarification
comment -- the A. randalli shrimp does not have the characteristics
of a mantis shrimp, but of a pistol shrimp. In fact, the common name
of your shrimp is the Randall's snapping shrimp. Many people
mistake the very loud popping noise of pistol shrimp for a noise made
by a mantis shrimp, but most mantis shrimp are actually rather quiet.
Well, until you give them some food.... but that's another
topic.)> Any information I can provide I will.... and thank you.
David Snider <Thanks for writing -- I now know the species name of
this cute little goby. --Ananda>
Pistol shrimp Hi guys, <Hello David> We have
one pistol shrimp in our fish only tank. Right now he has what looks
like the remains of a hermit crab in his barnacle home. Do they prey
on hermits? Or did the hermit die before and the shrimp just carried
off the rest? <Could be either... there are Pistols/Alpheids that
can/will attack, eat small Hermits. Bob Fenner> Thanks, David and
Christy
Pistol Shrimp(s) Hello, I started my reef keeping
experience with a Randall's shrimp goby. <My favorite shrimp
goby!> After hunting for a pistol shrimp for months I finally came
across one in a local pet store (right under my nose) It was a Tiger
(Bellulus). Within a half hour of adding the pistol shrimp to the
aquarium the goby and shrimp were best of friends, but alas, about 3
months later my goby died (my first and thankfully last fish death in
all this time). I soon picked up a very nice male Yellow Watchman and
the pistol shrimp took to it immediately. <Fickle those shrimps
are, aye?> I guess my point here is that in my own experience and
in all the articles I've read at other places on the net it seems
to be a theme that Alpheus Bellulus (Tiger Pistol Shrimp) is one of
the most readily goby pairing shrimps available (or maybe I just got
really lucky) <Yep, they're pretty slick like that.>
Anyways, about 6 months ago I witnessed to my horror that my tiger
pistol shrimp (which I had been keeping for nearly two years at this
point) was lying on his back just outside his burrow, molting and
looking very sickly with Bob (my yellow watchman) looking on
apparently in as much dismay as me. Not knowing what to do I just let
him be and crossed my fingers. I think my hermits finished him off in
the night. <Bummer, you might want to check your iodine levels as
a potential cause for a molting death> Being unable to
obtain a Tiger pistol locally I started looking on the net - where I
found a Alpheus soror (Clown or Bullseye Pistol) I am curious to see
if my Yellow Watchman and this species will hit it off or not. I have
been very unable to find any info on this species on the net
(particularly info on what goby species it likes to bunk up with) and
would love any info you guys could give me. <In most books this
shrimp isn't even ID'd to the species level> In any case
I'll find out if the two will enjoy each others company very soon
as my Bullseye Pistol will be here today before 4:30 CST via FedEx =
) <Heh, well I suppose you can tell us now! I'd say it's
likely, but not as likely as the rather easy going tiger pistol.

Preventative Pistol Precautions 1/13/04 Hi Crew,
<howdy> I was considering getting a pistol shrimp (possibly a
pistol-goby pair) but, after watching the Discovery Channel I am now
a bit worried. <there is a wide range of hardiness suitability for
aquarium use among this group... choose wisely> I watched the
pistol shrimp use its claw to stun, then eat a variety of
fish. Would my tank become a "shrimp buffet" if
I added one of these little creatures? The smallest
animals in my 180 gallon tank are a pair of maroon clowns, a royal
Gramma and a few hundred hermits and snails. I also have
three small yellow tail damsels but the shrimp can have them if he
wants them! <many pistols are quite territorial... more of a
threat to other benthic crustaceans (like shrimp) than fishes> I
am actually trying to find a way to get rid of these damsels (they
are attacking the royal Gramma). Any suggestions for
this? <they are greedy and can be trapped a number of
ways. Do manipulate keyword phrases to fin FAQs in our archives via
the google search tool on the home page. Some great ideas for
fish/invert traps inside> I am even considering adding a lionfish
or something that might eat only these small fish (leaving my clowns
alone) - ala "the lady who swallowed a fly". <neither
the pistol nor the lion is a viable solution. Trap instead. Even
drain and refill the tank quickly (15 minutes with a sump pump and
some garbage cans/pickle barrel) to net the fish easier> Thank you
for the help - it is greatly appreciated as always! -- Greg
<best of luck. Anthony>
Red Coris versus Pistol Shrimp Hi again, <Hello
there> Red Coris versus Pistol Shrimp.... who will win? <My
money's nine to one on the Coris... as a matter of fact, I was
just down at Ka'alu'u Beach a few days back turning stones
over to see what there was to see... and a beautiful pistol shrimp
was under one... I whipped my camera around... but too late... A
Coris gaimard that was following me about, to see what there was to
see under the rocks this crazy "bi-fin" was turning,
snapped it right up!> There's a Pistol Shrimp hiding out in my
130 litre tank... I'd rather he packed his bags and left, but
I'm not game to try to evict him.... and for 6 months he
hasn't caused anyone any trouble (to my absolute
knowledge). I - stupidly - believed everything I was told
yesterday at the LFS - must have had 'sucker' written on my
forehead - and came home with a 4cm Coris Gaimard. He's currently
hiding under the marine sand... now I've researched him on your
site - thank God for decent information - and realize the task ahead
of me to keep him happy. (I've also just suffered the loss of a
favourite seahorse in the other tank due to massive bad information
from this LFS... so very sad today.) <Live and hopefully learn>
Meantime - is the Pistol Shrimp a threat to him? <Doubtful>
Also - is he a threat to the other tankmates: anemone and pair of
clowns; 1 damsel; 1 flame angel; 1 canary wrasse; 1 blenny (he looks
most like your picture of Salarias fasciatus, I asked for a bi-colour
to eat the algae and was told he would do the same job); 1 sea
cucumber (also bought yesterday). <Mmm, only time will
tell... but I give you very good odds for many months that
they'll all get along> Should I try to return him to the LFS?
Thanks for your help. Regards, Wendy <Cheers, Bob
Fenner>
Re: Red Coris versus Pistol Shrimp Thanks! Maybe the
God of marine creatures was helping me after all... the little red
may solve the pistol dilemma. Lots of smiles Thanks.

Pistol Shrimp I did something stupid! <Hi Jason,
Don't sweat it we all have at one time or another, what's
up?> I have a 29 gallon fully stocked reef with many soft and hard
corals, clams and other filter feeders. I have a handful of small
fish - a mandarin, a yasha goby, an orange spotted goby, a long nose
Hawkfish, 2 clowns and a little blenny. the community was doing
incredibly well until lately, when I decided to get a couple of
pistol shrimp. first I ordered one, then I ordered what I thought was
2 different ones, and somehow received 3, so now I have a whopping 4
pistol shrimps (3 tigers and 1 cool red one) in a 29 gallon tank. I
had to screw up a good thing. how do I trap a couple of them?
<There are several mantis or shrimp traps you can buy or make out
there. Most are very easy. I'd suggest you start with the pistol
shrimp information http://www.wetwebmedia.com/pistolshrimps.htm>
and how screwed am I? <It depends on what you were trying to do
and what you want to do now.> so far one of the goby's is
trying to pair with two of the pistols, but they seem to dominate him
(they are approximately the same size, which may be a problem).
<Its good that they are trying to pair.> 2 of the tiger pistols
burrowed together in a little corner under a rock with about 2 inches
of sand, and seem satisfied. will they eat my brittle stars? <Not
trying to be wishywashy here but depends on the shrimps. And what
kind of "tiger shrimp" they are.> I almost hope so,
I've had a feeling that they were responsible for eating some of
my fish in the past while they were sleeping.<If the brittles are
green brittles you should get them out of the tank. Most other types
of brittle stars should be okay.> if not and I put some harlequin
shrimp in to eat the brittle stars, will the pistols kill the brittle
stars? <That depends on a lot of things including how much the
pistols are getting fed.> will these pistols shrimps
hold me hostage from here on in? I really want to trap at least 2 of
them and I'll most likely put them in another tank I have. help!
<Try this, http://www.seahorse.org/library/articles/DIY/diyMantisTrap.shtml,

Good luck, MacL>
Pistol shrimp Hi there, I have several
species of pistol shrimp in a 150 gallon reef tank. I have
a pair of yellow ones with purple claws with a black spot on their
sides. <Hmm, I think I've seen this species before
but not sure what the exact name is. I'm reasonably
sure it's in the genus Alpheus though, but I've never seen it
partnered with a goby like some pistols do.> Can you
please tell me some info on these. Do they eat fish?
Snails? <If they can catch sick or dying fish,
maybe. They could also be killing snails if they're
not being fed well enough.> I have been
mysteriously losing fish, and found the skull of my chevron tang in a
hole with one of these shrimps. <Not necessarily meaning it killed
the fish of course. it may have been eating the carcass> I do not
think I have a mantis shrimp, because I still have snails, and all my
smaller fish - gobies and quite a few cleaner and blood
shrimps. I have lost a pygmy angel, flame angel, chevron
tang, twin spot hog, just to name a few. <I doubt a pistol could
dispatch a full grown fish of this size. It sounds like
you could have something else going on in your tank. Do
you have other fish that are still
living? Corals? What are your water
parameters?> any info on these shrimps would be greatly
appreciated. <The only species I've kept purposely is A.
randalli, a goby symbiont. My experience was that it would
snap at just about anything in front of it, but rarely did damage to
anything larger than an amphipod. I kept this one with
several small gobies without any problems. I also kept a
larger tank with several pistol shrimps as hitchhikers. I
rarely ever saw them, but heard them snapping. This tank
housed a Kole tang, two small clownfish, and a damsel. No
problems there either. Hope this helps..> thank you

Pistol Shrimp and Featherduster Worm Meals
I've read that Pistol Shrimps will generally get along with other
invertebrates if they are well fed. <Yes, this is so> I've
had my Pistol Shrimp now for two years. At one point, I had
approximately 60 blue-legged hermits. They have been disappearing
quite rapidly... down to about 15 now within one year. As well, two
different Mithrax Crabs have disappeared. The Pistol Shrimp typically
resides in a particular area of the live rock. <Also common> A
few of the crevices where different rocks meet... have been piled
with hermit crab shells, snail shells, and even one Mithrax shell. It
has been suggested to me by a knowledgeable staff member at Big
Al's Aquarium that this is a sure sign of my Pistol Shrimp
preying on my snails/crabs... that he is 'decorating' his
lair? <Or just lazy re clean-up after meals...> As well, my
brittle or serpent stars seem to perish within a month... arms broken
off (I'm assuming eaten as opposed to fallen off due to water
quality). <Perhaps> If I am keeping my tank at a consistent
salinity of .0024 (not sure of the decimals), temperature a constant
26oc, other parameters are good.... Should my blue-legged's and
hermits be perishing without the assistance of my Pistol Shrimp???
<Maybe, maybe not> In any event, I have captured my Pistol
Shrimp (4 hours of live rock removal) and returned him to Big
Al's for an exchange. On another note, I did exchange the Shrimp
for a few creatures... including a feather duster. The feather duster
is quite large... about 3" diameter fan... I placed him at the
bottom of the tank in the sand next to some live rock. I couldn't
find any information on best locations to place other than embedded
in rock work or sandbed. I guess if he doesn't like the location
he will move? <Mmm, no> I plan on shutting off
powerheads/filtration for about an hour during my feedings and will
likely target feed the feather duster with a syringe with
brine/minced krill/blood worm mixture (it's a liquid). I did
notice my Coral Banded Shrimp snipped a very tiny piece of his fan
off... brought the piece of fan to his mouth... and then proceeded to
leave the feather duster alone. I am hoping he was just curious and
will now leave the feather duster alone? <Me too> If being
harmed, would the feather duster retract? <Usually yes> Thanks,
Dave <Welcome. Bob Fenner>
Pistol shrimp with other shrimp 6/6/05 Hey there, I
think I will go with the tiger pistol shrimp, but I am not sure if it
can peacefully exist with my 2 cleaner shrimp and a peppermint
shrimp. Do you think they will be ok? thanks again! <Pistol shrimp
with other shrimp can be risky. Although not predatory,
Pistol shrimp will aggressively defend their territory against other
shrimps, crabs, even fish (other than their
"watchmen")! Best
Regards. AdamC.>
Alpheids, polychaetes Hi again Mr. Fenner! Would a
pistol shrimp be of some use in controlling bristle worms population
or not really noticeably? Thanks! Dominique <The latter. Bob
Fenner>
Pistol Shrimp 1/27/06 Bob, <James
today> I have a 30 gallon oceanic cube, which has just completed
cycling. I have 10 scarlet hermit crabs, a few blue legged
hermits, a serpent star, 5 Nassarius snails, 5 Astraea snails, 2
turbo snails, 2 peppermint shrimp, 2 Pederson's shrimps, 1 skunk
cleaner, and an emerald crab. I also have a pair of
Perculas and a pygmy angel. I'm considering
adding later either a Coral Branded Shrimp or a Pistol/Goby
combination. I'm leaning away from the Coral Banded
because the size and shape of the tank will probably make his
territoriality an issue. I'd love to get a pistol goby
pair, I've seen them in larger tanks and it is just
neat. I've heard on a few websites that pistol shrimp
themselves may be a danger to my other
inhabitants. However, I have been able to find who are
likely victims of a pistol shrimp. Are there any species
of pistol shrimp which are less dangerous than others? <Size
usually dictates this.> Also, is there anyone on my list who's
a potential victim? <Shouldn't pose any threat with the
exception of smaller shrimp and very small fish. I have a
pistol in my tank sharing quarters with a scarlet cleaner shrimp,
snails, hermits, etc, with no harm done. James (Salty
Dog)> Sincerely, Derek
Pistol shrimp and Firefish
1/19/06 Hello crew, I recently 'bumped into' the topic of
mantis and pistol shrimps while looking for other info on
the site. I have a 75
gallon FOWLR. 1- 3" Naso Tang, 1- 3"
Coral Beauty Angel and 1-Firefish, and 1-Emerald Crab with
about 6 small hermit crabs. I placed my
first well-cured live rock into the display tank about 3
months ago. A 14# piece completely encrusted
with coralline and very craggy and
porous. I lost a coral banded shrimp and
probably 2 or 3 small hermits but no fish over the past 2
months or so. I have never seen any other creatures day
or night in my tank besides the ones I
purchased. I now know that the loud
clicking I have heard on and off is likely a pistol or mantis.
Yesterday I performed the club soda method with a baster
and also just poured some over the rock but I heard and
saw nothing. Since the Emerald crab and other
fish have been untouched and the clicking can be heard
when tank lights are on that maybe it is a pistol shrimp
rather than a mantis (pretty unscientific but my hunch
after reading all these posts plus additional research).
My Firefish has a nice little cave where some base rock
meets the substrate. Would the Pistol shrimp's
friendly relationship towards some gobies extend to a
Firefish and maybe he is living in the cave with him?
<Possible, but generally only associate/share with gobies as the
goby does shake the tail and warn the shrimp of any impending
danger. I have this relationship going on in my tank and
it is quite amusing.> Secondly, I would like to know if
you think I should continue to pursue this
unseen/unidentified culprit before adding more rock and
fish and eventually convert to a reef sometime in
the future? <Mark, I'm thinking you have a pistol
shrimp. The mantis shrimp is audible only during a strike
at prey whereas the pistol will click whenever
threatened. It is the incredible speed of the club like
front leg that generates the sound. Super high speed video actually
translated the speed to 75 feet per second along with the impact
generating well over 100x their body weight. To be sure
you could set up a mantis trap and see what you
catch. James (Salty Dog)> Thanks for the
help,<You're welcome> Mark
Re: Pistol shrimp and
Firefish 1/20/06 Thank you Mr. Sodium canine,<My,
what a title> To clarify then, if I end up trapping a pistol
shrimp I should remove him (her?) rather than keep in the tank?
<They are safe.> And definitely remove a mantis if
that turns out to be the noise maker?
<Definitely> Do you personally have
a preference for trap types? <I've never had the
need to use one so I have no preferences. Foster&Smith
sells one called the X-Terminator that looks like it would work well
for $16.00.> Thanks again, <You're
welcome. James (Salty Dog aka Sodium Canine)>

Pistol Shrimp/Trapping - 3/1/2006
Hello crew, <Hi Mark> You have helped me in the past and I am
looking for some additional advice now. I have the
following:- 75 gallon FOWLR with about 40 lbs of live
rock. I use 100% RO water.- ~ 1" of aragonite (I am
working this down during water changes to be closer to 1/2")-
Remora Pro skimmer- Eheim 2217 canister filter- Rio 1100 powerhead- 1
each - Firefish (Nemateleotris magnifica), emerald crab (Mithrax
sculptus), Coral Beauty Dwarf Angel (Centropyge Bispinosus), Blue
Tang (Paracanthurus hepatus), Raccoon Butterfly (Chaetodon lunula)
and 3 Green Chromis (Chromis viridis) .......and apparently one
pistol shrimp (shrimpis yuckis) I have been trying to trap this
bugger by using a trap with Mysis shrimp bait. How long
should I wait before changing the bait with fresh shrimp? <I'd
say three days.> Do you think the pistol will be interested in the
bait if it is beyond it's 'freshness date'? <Sure,
they are scavengers and take what they can get.> Is
there something else I can/should try as
bait? <It's fine.> I would really like to add
some cleaner shrimps but will not until I know this guy is gone. I
lost a coral banded shrimp which is when I made the connection about
the clicking sounds. <Are you sure this is a pistol shrimp and not
a mantis shrimp? Pistols are relatively safe in reef
tanks.> Also, my emerald crab became very reclusive after I
started adding iodine (8 drops a day) about 3 weeks ago. I
started adding it because he had never molted in the 6 months
I've owned him. Also, if I do get a chance to see him,
his shell has become more and more white. Is this part of
molting or should I just discontinue the iodine? <The crab has to
grow to molt. Maybe he isn't getting enough
vittles. The iodine present in reef enriched salts should
be enough to help with the molt, wouldn't have to full dose with
the iodine in this regard.> Thanks in advance for your
help. <You're welcome. James (Salty
Dog)> Mark
Pistol Shrimp 3/23/06
Hi! <Hello Tanya> I
have a question on pistol shrimp. I was wondering if there was an
actual list of pistol shrimps that are compatible with shrimp gobies
. There are some obvious ones like Randall shrimp, and Alpheus sp,
and candy striped pistol shrimp, and tiger pistol shrimp,
But I was just wondering if there were more pistol shrimp that have
shown some symbiotic relationship with gobies, perhaps just
hasn't been documented or maybe there's just only 4 pistol
shrimps that are compatible in the ocean with
gobies. Please help me find more symbiotic pistol shrimps
for my gobies. <Do keep in mind that the goby and
shrimp relationship is not automatic. If conditions are to
their liking they may hole up together. My pair took four
months before they got together. Anyway, there are a few
on our site which I believe you have already covered. Here
is a link to another site with ten more species. http://www.saltcorner.com/1024/index1024.htm Clicking
on the name will give a detailed description and usually a photo of
the shrimp in question.>
Thanks <You're welcome. James (Salty

Shrimp goby + pistol shrimp questions -
04/05/2006 Hi! <Howdy> I was thinking about adding either a
blue-spotted Jawfish to my reef or a shrimp goby with his pistol
shrimp. I decided to forget about the Jawfish because it's a
jumper. <Most all fishes, groups are> Some people told me it
wasn't true and they never had one jumping but I guess they were
just lucky, right? <Perhaps> A few things make me hesitate
about the shrimp + goby pair. I have been looking in my book Reef
Invertebrates and on the WWM but I am still unsure. My tank is a 90
gal open top with 5" sugar fine DSB. To be more specific, here
are the four shrimp gobies I am thinking about: Randall's,
Wheeler's, hi-fin red banded, yasha. Maybe you can advice me if
some are more suitable (in my case it would mean most likely to pair
with a shrimp and less likely to jump out of the tank). Apart from
jumping and pairing here are some other questions/concerns: -Noise
from the pistol shrimp. I heard everything from "can hear it
from the other end of the house and annoying when you try to
sleep" to "little clicking noise you hear from time to
time, not a concern at all." Is it really a concern? <Not
IMO> -On one reply on the WWM it is said that they can accommodate
themselves and dig in any kind of substrate even uniform sugar-fine
DSB. But should I add some rubble then? <I would, yes... Makes for
more interesting behavior> Don't want to add too much of it
because I think the fighting conch wouldn't appreciate... -Can
the pistol shrimp really pose a threat to other small crustaceans
(sexy shrimps), small fishes (clown goby, mandarin), or the fighting
conch (nicknamed Mr. Elephant...) in a 90 gal system? <Yes, can...
if hungry> -The digging of the shrimp should not be a problem for
the corals or clams located toward the bottom (covering them with
sand) if I place things correctly I guess. But can it mess up the
DSB/NNR methodology? <Can mal-influence this, yes. Best to place a
screen/barrier some distance/layer down to prevent it digging too
deep. Bob Fenner> Many many tanks ! Dominique
Pipefish and Pistol Shrimp 6/25/06 - Hi Bob,
<Hi there, Leslie in for Bob this evening.> I was just
wondering if its safe to keep a pair of bluestripe pipefish in a tank
with a pistol shrimp? <Not in my opinion. The only shrimp I would
consider with any of the syngnathids would be a few of the cleaner
shrimp'¦.. Peppermint Shrimp (Lysmata wurdemanni), Scarlet
Cleaner Shrimp (Lysmata debelius) or the White-Striped Cleaner Shrimp
(Lysmata amboinensis) .>Thanks. <You're most welcome,
Leslie>
Pistol shrimp and Jawfish, comp., esp.
Alpheids 5/16/07 Hello, <Hi there>
I seem to be having a turf war in my tank... <Very common... more
common than not...> or rather an invasion. Two days ago
my Jawfish left the burrow he's lived in for the last year and
moved to the far end of my 55 gal. tank. I noticed that
his caudal fin was split. Luckily he made himself a new
burrow almost immediately. Today his tail is almost
entirely healed and he's working on a new burrow behind a
convenient rock. While I was watching him dig this new
burrow, I saw a pistol shrimp (about 1.5-2 in) had set up shop in the
abandoned Jawfish burrow (I'm assuming the shrimp is responsible
for the Jawfish's evacuation). <May well be> Not only that,
but the shrimp had dug himself several new entrances and exits and
had also evicted my 2" hi-fin goby (Stonogobiops nematodes).
<Luckily not consumed (yet)> Now I'm worried that there
just doesn't seem to be enough room for everyone. The
shrimp's warren extends across nearly 1/2 of the tank floor and
includes the prime territory (well, prime at least from the human
observer's point of view). <Good point> My top
priority is making sure that my Jawfish to be injured again. Even so,
I'm a big fan of pistol shrimp. In my other tank I
have a mated pair of yellow watchman gobies with a Randall's
shrimp and the trio are definitely the highlight of the
tank. This pistol, however, is a different and larger
species, although I'm not sure which. I've looked
over the FAQs and articles, all of which indicate that pistol shrimp
are *generally* peaceful and *should* be harmless. <Uhh, no... or
at least would have to chat with you re your definitions of these
terms... Alpheids are territorial, agonistic... alpha organisms>
The pistol shrimp isn't bothering my other two shrimp, a fire red
cleaner and a peppermint (which have never had difficulties with
Jawfish either). Should I trap the pistol shrimp out, just
to be on the safe side? <I likely would> I've been thinking
of setting up a small tank (maybe just a 10 gal.?) for my second,
smaller hi-fin goby because he doesn't seem to be very happy in
the 55, spending most of his time hiding behind a powerhead, so maybe
I should move the pistol into that tank? <Mmm, I would likely keep
these separated... unless you can be very diligent in making sure the
Shrimp is well-fed> If so, would I still be able to keep the
little high-fin in there, too? <Not IMO/E> Thanks for your
help! -Lisa <Perhaps better to put the Pistol in a sump... Bob
Fenner>
Pistol Shrimp... A Soldier I Will Be...Two
Pistols On My Goby 12/4/07 Hey guys, <Got a gal today.> I
really relish all the info on your site and had a question of my own
for once. <Glad you have found the site helpful.> I was
considering buying a Randall's shrimp goby (Amblyeleotris
randalli) and a snapping shrimp (Alpheus bellulus) for my 20gal.
<OK.> Then I saw a video of two snapping shrimp working for one
goby and was like sick!!! <Heehee! Sweet!> How do I get two
shrimp to work for the same goby? <Have you heard the idiom
"You can leading a horse to water"? You can provide the
environment/circumstance but you can't make the shrimp do
something that it doesn't have a mind to do. Best you can do is
try it.> Thanks for doing this for everyone! <On behalf of Bob
and the crew, all are welcome. Mich>
