Is My Purple LTA OK?/Macrodactyla
doreensis/Health/Systems 1/29/10
Hello!
<Hello Dani>
So I need to ask for some help... I bought this purple LTA on
Saturday before doing any research (oops!). I have a 28gallon
Nano cube cfi that has only been set up for about a month.
<Oops again. Too small a system for keeping this animal and
much too new of a system.>
It looks like my lighting is 105w/8w cf quad;
<Borderline lighting at best for this anemone.>
115v-1ph-60hz and my pump is 16w/266gph.(this is off of the tank
specs) I have 20lbs of live sand and about 30lbs of live rock. My
friends living in the tank are 2 False Percula Clowns, 1
Peppermint Shrimp, 1 Fire Shrimp, 1 Serpent star, 1 sand sifting
cucumber,
<Tank too new, too small to sustain the cucumber, problems may
lie ahead.>
5 red leg and 5 blue leg hermits, 10 snails (2 kinds I can't
recall the names), 2 small Zoas and a hammer coral.
<Oops again, too small a system for keeping an anemone with
corals.>
My specs are: ammonia 0, nitrite 0, nitrate 0, ph 7.4 (working to
raise by adding reef builder to bring up alkalinity) dKH 8 (on
Sunday before lights out and after adding a dose of reef builder
that day), sg 1.022, temp 81. I have been doing a 2 gallon water
change once a week and I test parameters about every other day.
(I am very paranoid about my water levels). Anyway, this anemone
just sits in this spot and won't attach to anything and seems
to have a gaping mouth.
<It will not attach to rocks, burrows into the sand in nature.
This anemone will be short lived, I'd return if possible or
risk poisoning your entire system.>
I tried to get the best pics I could and after I took them and
was typing my email it shriveled up on one side. I am very
worried that this fella is going to die and kill everyone in my
tank.
<It will.>
I just wanted to know if you thought it would be OK or if I
should pull it before he does too much damage?
<Will not be OK, I'd try and return.....good luck here.
Should have researched this animal before buying, as to it's
needs/system requirements.
A little late now, but do read here.
http://www.wetwebmedia.com/macrodoreensis.htm>
Thanks!

Re Is My Purple LTA OK?/Macrodactyla
doreensis/Health/Systems, now Cuke comp. 1/30/10
Well now I'm a bit worried about my cucumber... I will have
to do some research on them as this is what the guy at my LFS
said would be ok for cleaning my tank. He is a very little fella.
Maybe 3 inches long... Anyway thank you so much for your
help!

Stocking Levels In A Nano Tank 1/17/10
Hi, it's Jordan again,
<Hello Jordan>
back for more advice. In my 10 gallon reef tank I have a small White
Striped Maroon Clownfish and a High Fin Goby with a Candy Pistol
Shrimp, and I was wondering if I could add maybe a big-ish Blue Devil
Damsel or
Yellow Tailed Blue Damsel to the tank, would the maroon clown and the
damsel live peacefully, I know the goby probably won't be a problem
because he'll be in the burrow most of the time.
<The Maroon Clownfish will soon be too large for this tank. Your
research would have indicated that full grown specimens can reach
lengths of up to a stocky 6". Unless you plan an upgrade, I'd
find a home for the Maroon Clownfish and add a Yellow Tail Damsel with
the goby. The Blue Devil is appropriately named and I would not add
this fish to your tank.>
thanks.
<You're welcome. James (Salty Dog)>

40 Gallon Marine Set-Up (Livestock & Equipment)
1/11/10
Hello Crew,
<<Hi Gary.>>
First of all I must compliment you all on this first rate site, you are
all very speedy with your answers and obviously very committed.
<<Thank you.>>
The knowledge here is absolutely astounding.
<Bob has certainly built an impressive database.>><Mmm, not
alone by a long shot. RMF>
I have a question about my short list of possible tank companions,
after I have added my clean up crew.
<<Okay.>>
2 x common clowns
<<I'll assume you are referring to A. Ocellaris or A.
Percula?>>
1 x royal gramma
<<Okay.>>
1 x dwarf angel
<<Which one? Some may be appropriate choices for your system (40
gallons is right on the cusp of being acceptable for a dwarf angel,
depending on the dimensions)'¦however, others certainly
wouldn't be.>>
1 x watchman goby
<<Okay.>>
1 x pistol shrimp
<<Okay.>>
Is this short list viable in the system I have, if so all is well. If
not can you tell me why and what you would change.
<<Just what I have noted above.>>
If all is well, what order would you put them in and would you put the
2 clowns in at the same time.
<<I would attain an established/mated pair if at all possible or
two viable juveniles.>>
My Tank stats are below.
40 Gallon JuweL Vision 180 with internal filter removed.
24 Pounds of Live Rock.
20 Pounds Coral Reef Live Sand.
Lifeguard FB 300 Fluidized bed filter.
<<I personally find these to be quite antiquated as far as
filtration for marine systems go. In my experience they end up being
more trouble than they are biologically worth, becoming detritus traps
and thus causing dissolved organic/nutrient issues. I would much rather
see a macro algae refugium or just the protein skimmer and liverock
with weekly water changes. With the liverock, I really think this extra
biological filtration would be redundant.>>
Protein Skimmer with a needle wheel venturi pump flow rate: 1850
L/H.
Wave Maker 6000L/H Powerhead.
Wave Maker 3000L/H Powerhead.
MaxiJet 600L/H Powerhead.
Thanks in advance
<<Gary note what I have written above, if you have any questions
feel free to continue the correspondence. Good luck.>>
Gary.
<<Adam Jackson>>
Re: 40 Gallon Marine Set-Up (Livestock & Equipment)
1/11/10
Adam,
Thanks for the answer, OK what dwarf angel do you suggest, I am open to
suggestions and if not a dwarf angel what other fish would you replace
it with. I know you dont want to make my choices but I want to get
balance right from the start.
So if that's OK with you if you could point me in the right
direction.
<<Hey Gary good to here from you again, I will direct you to our
page on dwarf angels and I will also make some suggestions myself if
you don't mind;
http://www.wetwebmedia.com/marine/fishes/angels/centropyge/
I would look at these;
Centropyge acanthops
Centropyge argi (Probably your best bet)
Centropyge aurantonotus
Centropyge fisheri
.....and of your list I would add this fish last after the tank has
sufficiently matured a few months at the least.>>
Thanks
<<Anytime, good luck! - Adam Jackson>>
Re: 40 Gallon Marine Set-Up (Livestock & Equipment)
1/11/10
Adam,
<<Welcome back Gary.>>
Cheers and just one more question I forgot to include, about my
fluidized bed filter you say these are a bit antiquated.
<<In my experience/opinion'¦yes.>>
I'm fine with that comment the only reason I included it was
because I haven't got a large amount of live rock in 24 pounds. Is
24 pounds of live rock sufficient in a 40 gallon tank with no other
biological filtration.
<<Depends on how porous the rock is, for example; a 1 pound piece
of rock could take up 4 square <<Cubic?>> inches or 10
square inches depending on how dense the rock is'¦so the
answer is yes if you have very porous rock this could be
enough.>>
Now I will look on the link at those dwarf angels you suggested.
<<That's the fun part.>>
Thanks again.
<<Anytime.>>
Gary

Wrasse suggestion for bristol <not the chicken> worm
control and Compatibility with neon gobies? 1/11/10
<Hello Gerald>
What's your experience with a wrasse in a 24g Aquapod tank with
neon gobies?
<Mmmm my opinion is that 1) You should not be putting any more fish
in your 24g and 2) There are many different types of wrasse. Some are
suitable for small tanks, some get to 2 meters+ long. What type of
wrasse are we talking about here?>
I've only 2 neon gobies and 2 Firefish.
Unfortunately I've several unwanted hitch-hikers. I've found a
large bristol worm (and others)
<Not unwanted in my opinion. A beneficial scavenger>.
Will the wrasse definitely take care of a worm even though the worm is
several inches long?
<Not likely at all, there are far more tasty things on offer in most
tanks than bristleworms. And unless you have seen the worm do damage to
anything (not likely) then I would just leave it be. These will
scavenge unwanted food/ detritus in your tank and will also reproduce,
creating real, living plankton in your system! This is the good stuff
believe me>
What are the characteristics of the 4,6,8 line wrasse?
<Ahh, OK we're not talking Napoleon here! Potentially aggressive
with your Firefish, and not worth the risk> thanks in advance for
your advice?
<No problem Gerald. If your system is running peacefully and
smoothly as it is I would not add anything else to it. By all means
monitor your livestock and the worm, and if there is a problem remove
it manually. If you have too many bristleworms this is usually down to
overfeeding. Cut the feeding back and the Bristleworm populations will
go back as well.>
Gerald <Simon>
Re: My tank-update 1/7/10
Hi Crew,
Yesterday I removed most of the rock so I could catch the Gramma. I
sold him to someone with a much larger tank. At the same time I removed
the lifeless body of the chalk bass. He must have just died because the
body was still whole. Actually I do not have much in the way of tank
cleaners except for snail algae cleaners. I do have some tiny worms
about the thickness of a hair. But no bristle worms and no Nassarius
snails and I don't like any crabs or shrimp. I have tried adding
Nassarius snails but they just do not stay alive. Maybe because my
substrate is crushed coral and not sand. Any suggestions for a food
cleaner upper would be appreciated. Should I add bristle worms? My
substrate is clean so it is not a major issue and I try not to over
feed.
<Mmm, read here:
http://wetwebmedia.com/marine/maintenance/maintindex.htm
the second tray down>
So now my 24 gallon has a spotted cardinal (6 years old), Firefish (1
year), a neon goby (2.5 years) and a green clown goby (2 weeks). Would
you add any more small gobies?
<Mmm, no>
I recently added a few mushrooms and was wondering if that was a bad
move because of allelopathy in a small tank. I have Candycanes and
hammers in the rock crevices and I put these mushrooms on the
bottom.
Thanks,
Sam

likelihood...

Re: My tank-update 1/7/10
Thank you BobF.
I actually have read those articles a number of times over the years
but a review/refresher never hurts.
<Agreed... I am often non-plussed to find I've written on a
topic... already!>
I also have another observation about my tank. I moved from a 5 year
old 10 gallon to my current 24 gallon exactly 1 year ago. At that time
I used some of my old rock and sand because the old tank was full of
little critters and worms and I wanted to seed the new one with that.
However after a couple months my new tank seemed to be devoid of any of
that life.
Maybe it was just too new overall to support that life. Over time I
bought new coral, added spoonfuls of sand from various tanks, bought
pods and also bought some Strombus maculatus hoping they would
propagate. It has been only during the past couple of months that I can
see that finally paying off. I see lots of pods on the glass, tiny thin
worms, worm fishing lines from both the rock and substrate, small
slugs, Asterina stars and lately saw a few dozen baby Strombus on the
glass (at least I assume that is what they are since the egg pods are
all over the place). This is a hobby that requires patience and it does
take time for a tank to mature.
Thanks for your help.

Please help - coral is starting to bleach! Sm. SW sys.
1/02/10
Greetings WWM and happy new year!
<Okay>
I had a bunch of frags (8) shipped three days ago. I acclimated
them very carefully this time (checked pH, salinity; kept them at
the same temperature as the source tank, and then dripped them in
over 5 hours).
They looked great after I put them in the tank (see pix). Put
them at the very bottom to allow them to acclimate to my lights.
I was off work yesterday so I did not see them. This morning one
of them (the Montipora in the pic) is starting to bleach at one
of the of the borders.
<I see this>
By this evening, the bleached area had advanced, and another edge
was starting to bleach (I don't have pictures of any of the
bleached areas yet).
Is there anything I can do?
<Yes... water quality tests... perhaps an addition of
iodine/ide/ate... Do you utilize a particular line/manufacture
for supplements? If so, I'd "keep them the same"
here... i.e., if using SeaChem, stick w/ SeaChem...>
It's already at the bottom of the tank. Should I try to find
it some shade? Or put it higher in the tank? Could this be
RTN?
<No, neit, negative>
All of the other frags are doing great except for the other
Montipora under the candy cane in the first picture, which has
white spots on it. Could the candy cane be injuring the
Montiporas at night? Please help!!
<Mmm, yes, though not likely much. I would have spaced all out
a bit more>
My tank is a 6 gallon Nanocube (about 12 inches deep)
<Very hard to keep Cnidarians in such small (unstable
chemically, physically... of times biologically) systems>
with 36 watts of 50/50 PCs running 11 hours/day.
<This is actually very little useful illumination>
It has a small fuge and I maintain the water parameters
meticulously. It's been running for a couple of months and
other than the new frags has some snails, a small Dottyback, the
candy cane head, a small Acan head, a Moseleya head, and a
Birdsnest.
Any suggestions you may be able to give me will be
appreciated.
<A larger system... perhaps buying such small specimens from
locals, a reef or marine club... at get togethers. A bit of
reading for sure re small SW systems: Start here:

Scooter blenny/ mandarin pale swimming in circles breathing
heavy 12/7/09
Hi thank you for your help ahead of time. I reference your site all the
time it is a wonderful source. I have scoured the pages and can not
find anything like my issue.
<Let's see>
I have a 2 year old 30 gallon mixed reef mainly soft coral and two LPSs
a frogspawn an a Galaxea.
<Yikes-ville! The last two alone are "super stinging"...
really need about a foot about them of "DMZ/No person's
land">
Only mentioning them because of there stinging ability.
<Ahh, I see you are aware>
I have a hang on back fuge on my tank with 3 inches of sand crumbled
live rock and some Chaetomorpha macro. It is only 1 gallon it is mainly
for breeding amphipods. My tank has about 35lbs of live rock and about
20
lbs of live sand. A Coralife super skimmer 65, a penguin 150 BioWheel
running carbon for mechanical filtration. A maxi jet 1200 and 400 power
heads.
Readings are Spg 1.022,
<Too low... I'd keep the density of water NSW, 1.025-26>
ammonia 0 nitrite 0 nitrate 5 temp 79 ph 8.3
I keep a tomato clown, a algae blenny, scooter blenny/mandarin, and a
short finned fuzzy dwarf lionfish. I know its a high bio-load and a odd
choice of fish to house together but I do a 5 gallon a week water
change and my
nitrates never go over 5 ppm. Everything besides the scooter have been
together for over a year and a half now.
<Can be done>
I received this scooter blenny about 4 months ago from a friend who had
a tank crash and had to get rid of him fast. I don't believe in
keeping mandarins at all because they all seem to die untimely deaths
in captivity.
IMO best left to the wild. That and I don't believe my tank was
sufficient size for it.
So my problem is my scooter who is nice and fat was always active and
eating copepods Has defiantly
<And likely definitely>
grown while in my tank. Was found this morning a very pale color just
sitting rather still and seemed to be breathing heavy. I found this odd
right away because he never stops moving. I checked all my water params
and showed the readings mentioned above.
<Mmm, no other fishes showing dire signs of stress I take it>
So I assumed he would be dead soon just by his actions. All the reading
I have done about them this seems to be a common sign of impending
death. I get home later in the day to find he has his color back, is
still breathing heavy but now he is swimming in clockwise circles at
the bottom of the tank and occasionally moving to a different spot. Not
doing his normal eating routine at all. Again I checked everything
still the same?
<Got me>
So I am curious if there is a chance he could have been stung by the
dwarf lion or is this a mal-nutrient effect or maybe just the end of
his life cycle?
<Likely is "summat he et" as they say in scenes of the
"olde S.E. U.S.... or a brush with some of the stinging life
here>
I have scoured your site and the internet and can not seem to find any
reference to scooters doing the circle thing. Only things I find are
loss of color and no movement.
Thank you for your time I hope you can offer some insight to what is
going on here.

<Thank you for sharing Nate. I do hope Santa or one his surrogates
is bringing you another, larger system. Your life here needs it. Bob

temp 25 salinity about 1025 with a trickle filter, the system has been
running for about 3 months. the "problem" is my blood shrimp
which has molted regularly ( once a month) after his last molt has

this has happened please help, everything else in my tank seems to be
good.

35 gallon Hexagon Lighting, stkg., reading
11/18/09
Hi again,
< Hello >
I have just finished reading about the lighting for my aquarium and I
am still not sure of what to buy. I have a 35 gallon hexagon which I
purchased years ago. I probably should have bought a new rectangular
one after coming across the problems with the lighting I'm
encountering.
Anyway, I have live rock, a tang,
< Your tank is much too small for a tang. >
goby yellow clown, Basslet, and Ocellaris clown fish, serpent starfish,
peppermint shrimp, snails, one emerald and one porcelain crab, also one
anemone.
< Overcrowded. Also, a 35 gallon is borderline for any type of
anemone. >
I would like to have two L.P.S.'s eventually. The top of my tank is
only about 20 inches across. I have a compact fluorescent on there now
that is extremely old and the company went out of business so it has
been very hard for me to find a lighting fixture that will work( one
that is only 20 inches across). The back of the tank has a protein
skimmer hanging on it so there is no room for a clip on light, unless
the clip is only 2.5 inches long.. After that being said..my tank is 18
inches deep and the top of the live rock is 6 inches deep. So the
corals would be anywhere from 6 - 18 inches deep. I don't want to
burn them up with too strong of a light but do want to give them what
they need. What can you suggest,,, please help. I have thought about
changing the protein skimmer also to try to add room for the clip on
light, but no luck as of yet..
What do you think I should do???? Thank you so much for your help and
time..
Cindy
< Normally I suggest T5 lighting for a tank of this size but because
of the shape of the tank , I would look into one of the many 150 watt
metal halide pendants on the market. Simply hang the light from the
ceiling and raise or lower the light as needed. As an option you could
look into a 24" 4 bulb T5 light. I know that the legs on Current
lights and a few others have the ability to slide in , fitting smaller
tanks. Not the most attractive way to go but very functional. Either
option would serve you well. GA Jenkins >
Stocking a 37/Stocking Level/Marine Set-Up
10/27/09
Hi!
<Hello Alissa>
Thank you for taking the time to answer my question.
<You're welcome.>
I'm finally setting up my first fish tank and I've never been
so excited. Even though I've never had a tank before I decided to
dive right in with a FOWLR. I've been reading a lot and also have
my expert sister for guidance. I have a 37 gallon (tank is 24'H x
30'W x 12'D) to which I'm planning on adding about 30-35
pounds of live rock and about 2-3 inches of live sand from fine to
rubble, 1 protein skimmer & 2 filters (along with other
necessities) to support 1 pistol shrimp, 1 smaller shrimp goby, 1
smaller serpent or brittle star, 1 emerald crab (maybe), 3-5 Green
Chromis, 2 Firefish, and 1 Royal Gramma (maybe). Do you think this will
be a good mix?
<The Chromis' are aggressive feeders and likely will not be
enough food available for the more timid Firefish. Firefish are best
kept by themselves or with fish of similar personalities/disposition.
Do read here. http://www.wetwebmedia.com/drtfshcompfaqs.htm>
I will of course be adding them gradually after quarantine in a
separate 2.5 gallon tank.
<This tank is too small for a QT.>
Also, should I add the 2 Firefish first and then the Chromis or vice
versa? I've read that the Firefish will be less territorial but the
Chromis will be hardier in a beginning tank. Then I will add the gramma
(maybe) followed finally by the goby. Thanks again for your expert
advice!
<A better choice would be two or three Yellow Tailed Damsels
(Chrysiptera parasema) to go along with your shrimp/goby combo and
Royal Gramma.
The Royal Gramma should be the last fish you add and the shrimp/goby
combo being the first. James (Salty Dog)>
Compatibility (Help) 10/8/09
Hey all,
<Jonathan>
I am turning to you all for some advice. I have set up my 29 gallon
Nano tank for about 6 months now, and finally added my final livestock
(Tail Spot Blenny) to my tank. I currently have a pair of false clowns
(1
black/white and 1 orange) and one Royal Gramma. The 3 have been living
in peace together for about 3 months now.
Since its been so long, I forgot that the most peaceful fishes should
always be added to the tank first, and the Gramma seems to be bothering
the blenny. I actually saw the Gramma take a pretty good bite of the
blenny as he sticks his head out of his "hole".
Unfortunately, he picked his spot right in front of the gramma's
"nest" and the blenny is cornered in it seems. Its only been
about more than a day but every time the blenny tries to leave his
"hole" the Gramma scares him back in. Will this continue?
Should I be worried about the blenny? Also, the clowns are very
curious, but I don't think they would do harm the blenny? Any
suggestions?
<Yes, in lieu of the tank being on the small side and easier to work
with, carefully rearrange the rockwork which will initially eliminate
territorial behavior. We are hoping that after this remodeling, their
new territories
will be much farther apart and hostilities will end.>
Your comments and advise are always greatly appreciated. Thanks in
advance.
<You're welcome. James (Salty Dog)>

Jonathan Tan
29 gallon stocking question
BioCube Stocking Options, First Time Reefkeeper -
09/22/2009
Hello guys,
<Ahoy!>
First thank you for all the great website. I plan on getting my first
marine aquarium soon and I have decided on a 29 gallon tank.
<It is my opinion that this is much too small a tank for a first
foray into saltwater. It can be done.... but larger is better. If you
do opt to move forward with this system, please consider keeping your
stocking density
quite low.>
The Oceanic BioCube if that is important.
<One of the nicer all-in-one tanks, but do keep in mind that, with a
tank like this (as opposed to a generic tank with regular components),
you are limited to what it comes with, and what modifications you can
do within the confines of the space provided in the system.>
I plan on the tank starting out as a fowler and slowly progressing
towards a reef tank.
<Tough to do in an unforgiving amount of space/water, but entirely
possible. http://www.nano-reefs.org has a section about modding
all-in-one tanks to make suitable reef systems; the BioCube has quite a
bit of
discussion there. You might want to check it out.>
I was planning on stocking the tank like this:
16-20lbs of live Rock (Fiji)
<The more the better - as long as there is space.>
20lbs of live sand
<Go with an inch or less of substrate, unless you're doing a
DSB, which I think is not possible in the BioCube. You needn't
spend the extra cash on live sand; it will become "populated"
with organisms and bacteria from the live rock.>
Ocellaris clownfish (Amphiprion ocellaris) ( I was also planning on
using him to cycle the tank. Is the species hardy enough?)
<No, absolutely not a good plan. This is a great fish for this size
tank, but no, do NOT cycle with this or any other fish. You're
planning on live rock, yes? That alone will cycle your tank. Please
read more, on WWM and elsewhere, on cycling, with live rock and
otherwise. Cycling with fish is unnecessary, harmful and damaging to
the fish used, and really not a good or easy way to cycle
anyway.>
Six Line Wrasse (Pseudocheilinus hexataenia)
<I, personally, wouldn't keep this in so small a tank.
They're surprisingly active, and will use all the space they're
given.>
Royal Gramma (Gramma loreto)
<Same as the wrasse.... though many would keep a gramma in this
size/shape tank. It could work. Bear in mind, though, that this guy
will be a touch aggressive, and may very well outcompete other fish for
food in such a small tank. I would NOT keep it in the same small system
as the Firefish you list below. The Firefish won't stand a chance
for food.>
And one Purple Firefish (Nemateleotris decora)
<An EXCELLENT option for a small system - and one of my all-time
favorites!>
or a Flame Hawkfish (Neocirrhites armatus) I hear that the Hawkfish may
fight with the wrasse.
<Nix the Hawkfish - they have appetites like you wouldn't
imagine, and will likely eat the crabs you mention below. They're
also a touch nippy. I would not keep this guy with the
Firefish.>
6-8 blue legged hermit crabs(Clibanarius tricolor)
<These are fine.>
and some assorted snails.
Would this stocking plan work?
<As above.... Might you consider a pair of clowns, and a pair of
Firefish, and omit the other fish? The Firefish will fare better in a
pair, and these four should get along well in the space of this tank.
It would also
make for a rather attractive display. You might also consider a couple
of Lysmata cleaner shrimp.>
I am fairly certain these are all reef safe.
<Depends on what you call reef safe. The flame Hawkfish is quite
adept at eating shrimp, crabs....>
I also heard the Clownfish may do better with a mate, but I think that
may be too many fish.
<The list you provided is "too many" in my opinion,
considering the aggression of and space used by the fishes you list.
There are many, many other options out there of smaller, less
aggressive, and less
space-consuming fishes. Four fish might not be too many, but the
activity level and aggression of the fish must be taken into
consideration.>
Is it better for me to introduce all the fish at once after the tank
has cycled or should I add them over time and if so what is a safe
introduction plan?
<As you list.... The hawk and gramma would be the final
introductions, with the Firefish and clown preceding them by two weeks
or more. But again, I really don't think your list would be
successful long-term, and
I'd hate to see that Firefish starve.... I trust you will be
quarantining the fish prior to introduction....>
Thanks,
Cory Prewit
<Good luck with your first foray into reefkeeping! I hope you'll
find it to be very rewarding. Don't stop reading, and keep
planning. You'll find success. Wishing you well, -Sabrina>
Green star polyps 09/14/09
I have a small 7 gallon saltwater tank that was given to me about 4
months ago. The tank has 1 spotted dotty back, 1 tube anemone, 5
assorted hermit crabs, 7 snails, 5 star polyps and 2 mysterious snails
I was told are conchs by fish store.
<My friend, you have far too many animals in this "tank."
Please remove all but the one fish, star polyps and maybe 2 *small*
snails.>
When I first bought my star polyps I had around 30 on a piece of live
rock.
After 3 weeks I noticed they were diminishing. I checked my water and
the levels seemed ok. To note due to small tank I change the water on a
regular basis as instructed by fish store. They said more if levels get
to high but 10 percent a week. I moved them to a lower flow area and
noticed these conchs followed and seemed to be pulling them off the
rock.
I have isolated these conchs and now my stars are not disappearing.
When I asked the fish store they said a conch will not hurt the polyps.
My question is what would hurt the polyps?
<Likely the hermit crabs, among other things... again, your system
is overstocked.
Cheers,
Sara M.>
Re: Green star polyps, Sm. SW stkg. -- 09/14/09
Crabs are bad news in small tanks. The store didn't lie to you.
They will eat some algae, but (in such a small space) they will also
pick at everything else too. As for the tube anemone... is there any
reason you can't just get a bigger tank? The tube anemone might be
ok for awhile, if you're really careful to keep the water quality
up. Very experienced aquarists could probably do this. But 7g is just
ridiculously small for a reef tank... very unforgiving. Do you think
you could upgrade to at least a 20g tank?
Best,
Sara
Stocking A 29 Gallon BioCube 9/9/09
Hi crew.
<Hello Jessica>
Thanks for your site and all of the invaluable info.
<Welcome.>
I purchased a 29 gallon BioCube and am currently in the process of
cycling it with about 40-50 lbs of LR and 35 lbs of live sand.
Everything on the tank is stock except I added the Oceanic skimmer
which seems to be working fine. I am a ways away from adding any tank
inhabitants but I have done some research
on specific fish and am looking for your expert opinion. I have a 2-3
inch sand bed because I am fascinated by the shrimp/goby pairs and am
thinking about getting a pair. Would they be ok in a tank this size
with a sand bed that deep?
<Sure, and an interesting addition.>
I am also interested in a clown fish but some seem to get rather large
for this tank. What would you suggest? Clown or no clown?
<Twas me, I'd go with no clowns, but two Ocellaris Clownfish
would work out.>
And which one? The other fish I like are Firefish and the Bicolor
Blenny (purple front with a yellow tail). Would these fish be ok in my
tank?
<The Firefish does much better in groups of three or more and in
lieu of this, would not be a good choice for your bio cube. The blenny
would be fine, but keep in mind they can easily exceed 3 inches in
length.>
Which ones are ok, if any, and what combo can I have?
<The above are fine, but keep in mind, four small fish is about the
maximum load for this system.>
Any other suggestions on fish selection would be helpful.
<Look at some of the colorful Dottybacks such as the Neon and
Sunrise Dottybacks.>
Thanks for the help :)
<You're welcome. James (Salty Dog)>
Re Stocking A 29 Gallon BioCube 9/9/09
Thanks for the help. Which shrimp goby would you recommend?
<No specific recommendation, but I like the Yellow Watchman
Goby.>
And as far as Firefish go I have read on your site that they don't
do well in groups..Maybe I am confused..
<You are not, Scott Fellman mentions this in Dartfish FAQ's, but
on the other hand Scott Michael (Reef
Aquarium Fishes) mentions otherwise. My opinion is that they do better
in groups and should not be kept with aggressive tankmates as they will
usually hide and refuse to eat. If I were to choose Firefish/Dartfish,
I would not include clownfish due to their more aggressive feeding
habits, likely
leaving the Firefish with unequal portions of food. A good place for
Bob's opinion/thoughts.>
<<...? The more popular species of Microdesmids kept by hobbyists
are almost always found in twos/pairs in the wild... Some, e.g. P.
evides, in social groups... This is stated on WWM. BTW, none are
suggested for such small volumes as this. RMF>>
Would I be able to have the two clowns you recommended and other fish
as well? The clown pairs can be pretty territorial right?
<As I mentioned, no more than 4 small fish including the clownfish.
The Ocellaris Clownfish can be
aggressive, but is generally limited to conspecifics and/or other
damselfish with similar personalities.
James (Salty Dog)>
Re Stocking A 29 Gallon BioCube 9/10/09
Ok thanks.
<You're welcome.>
And for part of the cleaner crew would a scarlet cleaner shrimp be
ok?
<Would be fine.>
Do the clownfish have to be in pairs?
<No. James (Salty Dog)>
Corals... sm. SW stkg. issues 08/02/09
Hey guys,
Love the informative website! My tank is doing well thanks to your
advice regarding stocking my tank. =) I finally took the plunge into
corals, and wanted to get some advice on how many hrs a day should the
lights be on for maximum health?
<10hrs to 14hrs, ideally. However, there's some flexibility if
you have different kinds of lights. For example, I know some people who
have both metal halide and VHO, who keep the metal halides on for 6 to
8 hours a day, the VHOs on before and after the MHs come on and
off.>
Currently I have some polyps and one xenia and though they do open up,
not quite as much as in the local LFS. I have placed them in the sand
to acclimate them to the Nano cubes lights, which should be sufficient
for these corals. Also, my snails and hermit crabs seem to always be on
their rock/frag which I know will cause the corals to close. Is this
something I should be worried about? I have 3 dwarf blue hermit crabs
and some nausarias/Cerith/Trochus snails. Any suggestions on how to
give the best care to the corals?
<In a Nano cube? Your biggest challenge is going to be keeping the
water quality high enough. Do plenty of water changes, be prudent about
matching temp/pH/etc. of change water. Run plenty of carbon, keep your
filter clean. Don't overstock with fish... you know, just keep the
water quality as best you can. If you do so, these corals will likely
"forgive" less-than-ideal lighting (once they adapt to
it).>
Thanks again.
Jonathan

Sara M.>
Tank livestock, sm. SW 08/02/09
Could I put a clown fish a blue tang and a yellow tang in a 38 gallon
tank?
<No. Please research these fish here on WWM, elsewhere. Once full
size, these will be too much bioload for a 38g tank. Also, tangs need
*at least* 55g. -Sara M.>
Re: Tank livestock 08/02/09
Not even just one of them?
<One of what? One Tang? No... not in a 38g. You can keep a clown
fish in a 38g. -Sara M.>
Re:... Stocking 38 08/02/09
Hey crew! I just added my first fish yesterday to my 38 gallon tank a
clownfish and a Chromis I want to add a small tang I have read they
will grow to fit their tanks but on another note could u name some
other good
fish for my size tank? Pls answer I haven't received answers to
many of my past questions
<My friend, you have received responses (you even responded to one
of them). And again, no, you can't/shouldn't keep a Tang in a
38g tank. No, they do *not* grow to fit their tanks! With only 38g, you
should stick to fish that are smaller and don't need a lot of
swimming room. Some good choices might be gobies, blennies, clownfish,
etc. Please see here:

Scroll down, look under "Small Marine Systems (< 40

Re: Stocking 38
Alright thanks and the one I replied to about stocking it was after I
sent the message saying I didn't get a reply but thanks!
<Ok, cool>
Shrimp Question, comp. 7/31/09
Hey all,
<Jonathan>
I have a 24 gallon Nano cube with about 20 lbs of live rock. I
currently have 2 cleaner skunk shrimp and was thinking of adding either
one or 2 blood fire shrimp.
<Mmm, I wouldn't... not enough room here>
Will they coexist together?
<Maybe not; particularly during moults>
At first, I got 2 cleaner shrimp because they are more active and less
shy than the fire shrimp. However, my 3 yr old son loves the fire
shrimp and I would love to get one for his birthday this weekend. Will
they
coexist together?
<...>
Will it be more beneficial if I get a single red blood or a pair?
Current tank mates are one orange and one black/white clown and a royal
gramma.
Thanks again for all your help.
Jonathan
<I'd stick with what you have or trade them for the L. debelius.

My tank. Sm. SW stocking issues... reading
7/30/09
Hi Crew,
After 5 years with a 10 gallon I upgraded to an Aquapod 24 gallon and
moved my fish and corals to the new tank back in January. The new tank
has an hob skimmer and 65 watt pc's 12k daylight. Added all new
sand (sugar texture) and rock. The fish I had were a spotted cardinal,
a neon goby and a clown goby. The coral was Candycanes. I added two
heads of frogspawn and 10 heads of a hammer plus a four inch square
Favites. I added a Firefish
<Is a social species and needs more room than this>
and a chalk bass. Then I added a false Percula and 2 more Firefish. One
Firefish lasted a day and the other about 4 weeks. Then my 6 year old
clown died. So Now I had the spotted cardinal, neon goby, chalk bass
and clown. The clown is not as docile as my other fish even though he
is just about and inch so I was thinking I should remove him. But he
was so active he made the others come out and swim in the open so he
stayed.
Then a couple weeks ago I saw some fish on sale and I got a blue
Chromis, a royal gramma, a red spotted Sandperch and a citron goby.
<... troubles>
I had actually ordered a yellow clown but the citron is what came and
it is much bigger than what I expected. So what is my rational for all
this. The Sandperch stays on the bottom (except during feeding). The
cardinal hovers but does not move around much and he is larger than the
others. The Firefish and the neon goby are similar in how and what they
do but seem to get along.
The blue Chromis is an open area swimmer near the top and the chalk
bass is an open area swimmer but more towards the middle. The Gramma
goes around but tends to stay close to the rock. The citron goby just
parks himself on a Candycane and watches everyone else. However he is
not eating like he should. I have seen him take something but not
regularly. His eyes look a little cloudy and I am wondering if he has a
problem seeing. The Percula clown is all over the place and during
feeding fights with the chalk bass. That is the only aggression that I
see. So there are a lot of fish they have different tendencies so my
feeling is it should work. I will remove the clown. One of my concerns
was where they would all go when lights are out so I made sure there
were plenty of hiding places in the rock. I do have Cyano but it is not
out of hand and is mostly on a few patches of sand which I stir up once
a week. I assume you think I should remove some other fish as well.
What would you suggest.
Thanks

Condy Anemone 7/14/09
We have just started our first saltwater aquarium and purchased a
Condylactis anemone.
< Anemones should never be placed in a newly established aquarium. 6
months to a year minimum. >
It is pink/white and has purple tips. I have read a lot about these
anemones but still have a question or two about it. First here is some
information on our tank. We decided to start small. So we have a 20G
tank.
< Too small for this animal. >
It's inhabitants include:
1 1/2 inch substrate
6lbs dead rock
10 1/2 lbs live rock
5 hermit crabs (red legged)
3 snails
1 Skunk Cleaner Shrimp
1 Black Brittle Star
1 Royal Gramma
1 Lawnmower Blenny
< Can become aggressive in small environments. Especially as they
age. >
2 Percula Clowns
1 Pencil Sea Urchin
< Could cause injuries to the anemone. >
1 Condylactis Gigantea
(We also have some Ricordea, a few tiny feather dusters and 5 teeny
tiny sea stars that came on live rock) (Not sure if I spelled
everything right! sorry)
< Tank is overcrowded. I would remove at least 2 of the fish. I
would suggest keeping the Perculas.>
The only thing that I know about our lighting is that it is 15watt
fluorescent. I do know that anemones need strong lighting.
< This is not nearly enough lighting. >
I target feed the anemone a small piece (1/4 inch or smaller) once a
week and feed the tank a 1/2 cube of Mysis shrimp morning and night. My
water quality is excellent...1.024,
< I would slowly raise this to 1.026 >
8.2. 76 degrees, 0 for all levels it should be and so on.
After having the anemone a week now it is still "free
floating" in one spot in the tank. It has not attached it's
foot anywhere!
< This is not a good sign at all. >
Questions:
Is it normal that it hasn't attached yet?
< Absolutely not. This is a sure sign something is not right.
>
Should it attach to something or will it always float?
< A healthy anemone should attach fairly quickly. >
Is my lighting good for this anemone, or do I need more?
< Your lighting is no where near enough. You should look into a 4
bulb T5 setup. Look for one with individual reflectors. You should also
increase the feedings to help supplement the poor lighting. >
Also my anemone keeps "deflating" and "inflating",
I know this is normal because it has not been in the tank long but do
you know how long before they start to stay "inflated"?
< The inflating in deflating could just be the animal expelling
waste. >
I really love this animal, it is SO gorgeous and want to do anything I
can to make it happier. We are in the process of getting a bigger
tank.
Thanks for any help you can offer!!
< A bigger tank is a good step but lighting is an immediate need. If
a new light fixture can not be purchased quickly , you may want to
consider returning this animal until you are more prepared to care for
its needs. GA Jenkins >

Fish compatibility. Sm. SW, reading 7/11/09
I have a Finnex 20g M tank, and am wondering if the fish I have
selected will survive in that tank. here is the list:
1 Tail Spot Blenny
1 Twelveline Wrasse
1 Griessinger Goby (Discordipinna griessingeri)
1 Bluespot Jawfish
One of my concerns is that all the fish but the wrasse seem to be
bottom dwellers.
thanks,
Randy
<Mmm, maybe the Goby listed but... this system is too small for a
Jawfish, a lined wrasse or Ecsenius species. "Back to the drawing

Condy Anemone 7/2/09
Hello and thank you for such an interesting and informative site.
My local shops are all too arrogant to chat it up, or only
interested in selling, to be of any real honest help.
<Sad and all too common.>
I found this site by Googling, and it is the only one with
specific and informative help.
<Thank you.>
To my problem.
I am including a pictures of my Condy Anemone. I bought a Nano
system from the shop that already had been cycled and had a Condy
and another fish I have since removed. The Anem started out fine,
but the tentacles are all withered and falling off. His body
looks healthy, and he has only moved once. I keep the water clean
and within the parameters you have advised here.
<Can you provide specific numbers?>
He eats a small piece of squid eagerly three times a week, stays
swollen up, but these tentacles are all dying. Please
advise.....
<A few things come to mind, particularly the system size. Most
"Nano" sized systems are really not appropriate for
most if not any anemones. The size alone is an issue, but the
stability (lack of) that comes along with a Nano size is another.
Also, how about lighting, filtration and water flow in this
system? All play into the health of your Condy. Scott V.>

|
Re: Condy Anemone 7/3/09
Just as I said about my local store just wanting to sell me
something. They highly recommended this setup.
<Not good.>
My parameters are
ALK. 180
PH 8.2
NO2 0
NO3 10
It is pretty consistently there.
<Is the temperature consistent?>
Filtration is two sponge cubes, then
charcoal bag in section two. I have about 10 lbs of live rock in
there.
The lighting is the Nano DX hood. Two double fluorescent bulbs, one
white one blue. I started the Anem directly below good light, about
4-5 inches deep, and he moved to a shadier area. The flow is a
power head pointing away from him, but he gets decent tentacle
movement, the ones that are left anyway.
<This system really is not suitable for this anemone. It sounds
on the small side for both growth and stability. The lighting too
does not sound like it is likely enough based on what you have
stated.
See: http://www.wetwebmedia.com/condysysfaq.htm
and the linked files above.
