Ulcer? 4/27/20
Good evening.
<Hey Hector>
I asked my friend about an ulcerative lesion on my clown’s jaw, and he told
me to email you.
Here it goes.
Just noticed it today. It’s not eating because the mouth is constantly open.
I plan on quarantining, but don’t know what meds I should try.
<Mmm; unfortunately there is no treatment for such a situation (that I'm
aware of); on the plus side, having seen and read re similar circumstances I
don't consider that this condition is "catching"... that is, it won't spread
to other livestock>
Thank you for your time.
Best regards,
Hector
<Were it my fish, I'd keep it as long as it doesn't seem to be suffering.
Otherwise, please see Neale's piece here on euthanasia:

Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/27/20
Your replies are always so insightful and they give me confidence with
the choices I’ve made.
Regarding the Bannerfish, I read in a WWM thread where you were
answering another hobbyist’s emails. In that email, the hobbyist
mentions that even the Bannerfish is not a true beginner’s fish. That
it’s somewhat hard to
keep and doesn’t beat in a tank that’s been up and running for at least
six months. Have you found this to be true? Are they a very hardy
species?
<... Andrew; did you get your tank installed, up and running? My
opinions re Heniochus BFs are archived on WWM>
Are they the hardiest among butterflies, or even among marine fish in
general?
<As stated>
Setting up a quarantine system would be difficult for me to do due to
space constraints in an apartment. Are the species I’ve mentioned
generally exceptions to the need for a quarantine regime? Just in case
you don’t
remember, I will include them in the order I plan to add them:
One-Spot Foxface + x2 Ocellaris Clowns
(Wait 1 month)
Either Marine Betta or x3 Pajama Cardinals (3 juveniles 3-4 cm, add them
together)
(Wait 1 month)
Add the fish I didn’t add last time
(Wait 2 months to let tank stabilize a bit)
Add x3 Stripeys
(Wait another 1-2 months)
add Bannerfish
(Wait 1 month)
Add Flame Hawk pair
(1-year mark- maybe a Centropyge angel)
I will make sure to only buy healthy, alert, and feeding specimens from
my LFS. They will be observed in the follow-up period between adding
each new fish or group of fish.
My LFS does treat most of their fish using copper.
From the research I have done, a tank around my size would be 2000-2500
pounds after being filled with live rock and water to the appropriate
amount. That’s a lot of weight My building is a typical service
apartment
that was completed in 2016 or 2017, should it be able to sustain that
weight without too much difficulty?
<I would have a certified structural engineer come, assess your
situation... need to spread the weight out, place near/against weight
bearing wall/s>
Also, I will be putting my tank near the corner of the wall. I heard
that’s where structural strength is the greatest.
<Ah yes>
As for pairing my Ocellaris Clowns, I’ve read pairing a smaller clown
with a bigger clown is the way to go (is it the same for all clowns?
Even captive bred?). This is to ensure the larger one becomes the female
and leads the smaller one (which will become male) into submission. Not
sure how much aggression there is involved, but I plan to get one in the
4-5cm range (1.5-2 inches) and the other around 2-3cm (or 1 inch to
slightly over 1 inch).
I’ll be cycling my tank using clean / cured live rock. I plan to let it
cycle for 4-5 weeks, maybe a sixth. I’ll ensure ammonia and nitrites are
exactly zero, and nitrates at an acceptable level of about 2-5 ppm
(though I heard soft corals like “dirtier” water)?
For me feeding regimen I plan to feed 3-4 times a day, the Marine Betta
will be fed 3 times a week. I plan to feed a combination of dry (Ocean
Nutrition Formula-1 and Formula-2 flakes and pellets, Hikari A and
Hikari S, Omega One Shrimp Pellets, Hikari Seaweed Extreme, Hikari Algae
Wafers), frozen (Dr. Basler Caviar, First Bite Fish Eggs / Calanus
Liquid, Hikari Frozen brine and Mysis, Hikari plankton / Rotifers /
Gammarus, First Bite Copepods). Also frozen bloodworm cubes that I can
get locally. Nori strips, Julian Sprung’s Sea Veggies will also be
crucial for my herbivore (Foxface) and omnivores (Bannerfish, Stripeys,
Clowns).
Live foods unfortunately aren’t an option for me. Marine Betta- I am a
bit worried. The closest I can get to live are fresh / frozen seafood
and seaweed which I plan to include in my fishes’ diet once a week,
every Sunday.
I always write such long emails, must bore you. I apologize, but once
again I’d like to tell you how much of a help you’ve been to me now
taking steps towards making my childhood dream a reality.
Sincerely,
Andy
<As much fun as it is to dream, plan for livestock arrangements,
you should (again) focus on the system itself at this point. Hoping this
is clear. Bob Fenner>
Re: E. Pacific Anemones husbandry
4/26/20
My total water volumes consists of a 35 gallon display aquarium with 1"
acrylic on all the sides and bottom.
<Good for insulation>
I have a good 1/10hp chiller and haven't had any issues maintaining
55.5-56 degrees F, which is currently
my target temperature.
<I'd let this up during the summer/warmer months... high 50's, low 60's>
In addition to the anemones I have many macroalgae and so I have strong
lighting optimized for plant growth, though I've considered switching to
bluer light for aesthetic purposes.
<... the strength of lighting is a relative term... 40-50 PAR, PUR for 8
hours a day is fine>
Plenty of flow between return pump, chiller pump, and two DC Tunze
powerheads. Plenty of bio media. I am planning on drilling the aquarium
and adding a sump to increase water volume.
<Ah, good>
My ph has stayed fairly low around 7.6-7.8- I think the chert rock and
sand (common in my area) contributes to this.
<I'd be adding a commercial supplement here. SeaChem Stability is a
fave>
Nitrates and phosphates have stayed high, especially phosphates
(0.4mg/l, nitrates around 25mg/l).
<Not a worry>
From my discussions with other keepers of coldwater aquaria, these
slightly elevated numbers are not uncommon but I would still like to get
them down. When I add the sump I'll have a lot of options there, so I am
not too concerned.
<Good... DSB there, RDP... BobF>
Glass aquarium on an acrylic stand?
4/25/20
Hello and thank you in advance!
I have an old, scratched up (I believe* 75 gallon) acrylic tank with
a matching acrylic stand (Tenecor). If I bought a glass aquarium do
you think it would be safe to use the acrylic stand for it? The
acrylic stuff seems
so perfectly paired, with so much even contact. I worry the heavier
glass aquarium with its stress points might not match up. Any
thoughts? Thank you again.
Lance
<It should work; that is, all the commercial acrylic, made for
acrylic tank stands I've encountered have been sufficiently strong,
level and planar to accommodate the same size (base) glass tank. IF
you're concerned re the contact points, do consider first testing to
see if (with filling the new tank on the stand), that there are no
gaps twixt the face of the stand and tank itself. IF there are small
ones (like a credit card width), insert a
piece of foam (Lowe's, Home Depot...) between the two. IF there
is/are large/r gaps, put a cut piece of plywood between them. Bob
Fenner>
Re: Glass aquarium on an acrylic stand?
4/25/20
Thank you for your prior answer! I have one more related to tanks.
Is it abnormal for a glass aquarium to bow out, or should it be
perfectly straight?
<Glass does bow... not often perceptibly... but yes>
I have a common 55 gallon (48”x12.5”x21”)
<Okay... I recall the width as 12.75">
that is half an inch wider in the middle (13”, measured on top) than
it is on the ends. And the middle plastic support brace is almost
disconnected now on one side.
<Mmm; well; you DO want that plastic bracing (or a retrofit, like a
Euro-brace) in place. Manufacturers do offer, sell replacements>
I am kind of freaking out, now that I know this. That’s what
prompted my prior question, and am frantically looking to replace
this tank out of fear that it is about to go. It’s an old tank, with
a 17-year-old Ocellaris clown as one occupant. And she’s my baby and
I want no harm to come to her.
<If practical I would drain the water down 5... 6 inches at least
for now. Bob Fenner>
Re: Mature Tanks - Diatom Bloom 4/25/20
Thank you for the response, Wil.
<Welcome>
Not sure if you got my attached photos?
<I did,... are already posted on the daily FAQs. The only way to be
absolutely sure of the type of “Algae”, is to take a sample and see
it under a microscope, many look pretty much alike, that’s why we
have to rely on the antecedents of the particular system.>
A little more info on the timeline...
I had a perfectly beautiful tank and went to Europe for 4 weeks on
vacation while a friend monitored the tank with water top-offs and
feeding. I returned to chaos and a mess of a tank. Algae everywhere.
Some water changes, etc... I had it looking good again and my chaeto
that I had at the time had turned black so I tossed it. I ran
without chaeto for awhile, and my nitrates then increased from 0 to
as much as 30 or so ppm, and it seemed my corals were suffering. I
then purchased some chaeto from the hobbyist and had the bryopsis
outbreak very soon after. I fairly quickly resolved the bryopsis
outbreak with fluconazole, but then started to experience the diatom
algae and had some nitrates in the 20ppm range. I just recently
added the good batch of chaeto and it has resolved my nitrate issue,
and finally my corals are looking good... but the diatoms are still
there.
Thus, I hear what you're saying... but the Dino was present even
when my nitrates were in the 20ppm range.
To answer your questions:
It first looks like a rusty dusting over sandbed and then rocks.
There might be the smallest of bubbles that form followed by green
hair algae. It is not present in shaded areas, no.
<Those are indicators of Dino infestation.>
Ph is consistent at 8.2 since I started the tank
The tank is an Innovative Marine, thus the sump is actually the back
portion of the tank. If I add anything back there, it'll be a bitch
to ever get it out...
<Understood, it’s impractical to add a DSB there.>
but I hear what you're saying. On my old 90g reef, I had a deep
sandbed in my refugium and my setup was pretty slick and trouble
free - never even had to clean the glass of algae.
<That’s why I suggested that.>
If I alter my lighting to 6hrs a day with more blue (on these
Kessils there's only a percentage setting, so I am assume I just
keep my color around 20% or less?), do you think I should keep my
intensity as is?
<The bluest spectrum your Kessils provide is okay, just don’t use
the light spectrum on the lower Kelvins range.>
Do you perceive any coral impact to a color adjustment?
<Not too much as this is going to be temporary.>
As far as equipment, on a scale of 1-10 I'd rank my Innovative
Marine skimmer around a 6.
<Yes, the biggest drawback is that it is very difficult, almost
impossible to fine tune.>
I do get wet skim and bubbles constantly, but then again I wonder if
it's because the tank is fairly clean?
<Could be>
Investing in presumably a better skimmer vs adding a uv sterilizer.
Go with the UV Sterilizer?
<For now, I’d go for the UV to kill any floating micro-organisms
that are causing this issue. Wil.>

Keeping E. Pacific (coldwater) anemones; system
4/25/20
Hi Mr. Fenner,
<Jonah>
I have listened to a couple of your talks and used your website. I
have found all the information you put out extremely interesting.
<Ahh>
I am attempting a cold water pacific-coast setup with anemones.
<Oh!>
I was wondering if you have any advice as to the care requirements
of Anthopleura sola, A. elegantissima, or anemones the Urticina
genus.
<I know a little; have kept the local anemones, studied the elegant
clone in college... histologically; have friends who are coldwater
keepers, and volunteered years back at the local public aquarium
where we kept
Metridium, Tealia... species>
I don't have a separate system to exchange water with to allow new
additions to slowly get to know one another as you have suggested.
<Mmm; not necessary. Do need a chiller>
I'm trying to run a lot of carbon and to match their environment in
terms of temperature and flow.
Are there any specific things that you would recommend I try?
<Well, need to know a bit more re your set up... size, gear make
up... Do tell>
Thanks very much,
Jonah
<Glad to share. Bob Fenner>
Blue Angel (RMF?)<<Nothing more>>
4/24/20
Hi, a friend of mine told me about your site.
<Well, that's nice.>
I was wondering if you could help me out with 1 of my Angels. I thought
she may have been carrying eggs but that was about 2 months ago and
she's still bloated. Others I have asked said it appears to be a tumor.
<Indeed. Much less good news here. Does appear to be a tumour, but
whether benign or cancerous impossible to say. You could lift the fish
out gentle with a net, and using wet hands, just feel the lump very,
very gently. If it 'gives' easily, it could be a fluid build-up, what is
properly called oedema, but widely known as Dropsy. Normally this
happens around the abdomen, but can happen elsewhere. The use of Epsom
Salt in the water (1-3 teaspoons per 5 gallons/20 litres) can help,
along with a suitable
antibiotic. But if the lump feels more or less solid, then it's a cyst
for sure. Be sure not to apply any pressure anywhere other than on
muscles -- pushing down on the abdomen (bottom half of the fish between
the head and the vent) can damage the internal organs and kill the
fish.>
If you believe it is, is there anything I can do?
<No. Benign cysts are not lethal unless they obstruct an important organ
or blood vessel. Since this cyst appears to be on the muscles between
the abdomen and the tail fin, this is unlikely to be a dangerously
located cyst. In some situations these benign cysts clear up by
themselves, perhaps triggered by a bacterial or viral infection, but
more often they're permanent, and perhaps genetic more than anything
else. The more inbred fish are certainly more prone to them than
wild-type fish, so you do tend see them in things like Goldfish, Koi,
Bettas and fancy Angels and Guppies.
If the tumour is malignant, there's no real treatment nor much hope.
Thankfully, such tumours are rare in tropical fish. But if you did see
the fish obviously suffering, then humanely destroying it would be best
(the Clove Oil method is safe, cheap and easy to use). Incidentally,
vets can remove cysts and tumours from tropical fish, but it's usually
only practical and cost-effective for things like Koi>
Any Meds? I started changing the water every 3 days at 65% instead of
every Saturday at 75% (some suggested more water changes )
<Up to a point, optimising water conditions will certainly help
generally, and a healthy fish is one more able to use its immune system
to deal with problems. But benign cysts tend to be very persistent,
though they do, sometimes, subside themselves (indicating, perhaps, a
viral or bacterial component). It's really more about ensuring the
Angelfish is able to swim about and behave normally. If it can, then I
wouldn't be overly concerned.>
Any help will really be appreciated. Thanks so much
Dennis
<Sorry can't offer much more help than this. Cheers, Neale.>

Mature Tanks - Diatom Bloom 4/24/20
Good afternoon!
<Hello Dave!>
I'm frustrated to the point of wanting to take a hammer to my tank (ok not
quite yet)
<Ahh!, been there several times in the past 30 years, this hobby demands
patience>
Going on 18yrs in the hobby, and I had a previous 90g reef tank and 200g
predator tank running beautifully without issues after a 3yr trial and error
period. With a move, I gave up the other tanks and now have a 60g reef. I
very quickly seemed to have that tank under control within the first year,
but at the start of year three I used some chaeto from a local fellow
hobbyist that seemed to be plagued with bryopsis. Within two weeks of using
his chaeto, there was nasty green algae everywhere...
took a while to figure out it was bryopsis, and I soon had that under
control with fluconazole. Since then, I've been getting what appears to be
diatom algae.
It's not cyano. I <It> starts on my sand bed at the front of the tank, and
then shows up on some of the surfaces of my rock where I don't have corals.
<Is it present even on the shaded areas?... have you seen any small air
bubbles on the top of the sand or rocks where it has grown?>
I use RODI, have changed filters on schedule, and my source water readings
are Ammonia, Nitrate, Nitrite, Phosphate all 0 readings.
<What about Ph?>
I was suspicious of the Phosphate test and bought a Hanna, and confirmed it
was in fact a zero reading. I'm confident my source water is good.
<Okay>
Feeding... two Clowns, a Foxface, Royal Gramma, Peppermint Shrimp, Cleaner
Shrimp, Sebae Anemone, Banded Serpent Star, maybe 20 blue legged hermits, 5
Nassarius Snails, and four other assorted snails. Frogspawn, Colt, assorted
Zoas, and a Toadstool. I figure I have a relatively light load for a 60g
tank.
I feed half a cube of frozen 4 times a week, and pellet 3 times a week -
just enough that it's all consumed. I think if anything I am feeding light,
my Foxface could use some additional weight.
Other nutrient control: skimmer that produces some pretty wet skim and it's
hard to adjust properly.
<A good, reliable protein skimmer is very helpful in maintaining top water
quality.>
It definitely could be better, but then again I have a very light load I
think.
I have chaeto in a refugium that grows like crazy I rinse and garbage a 1/3
of this every week during water changes that are 10%/week. My tank water
parameters are ammonia, nitrite, and phosphate 0. My nitrate will sometimes
give me a small reading of 0ppm to 10ppm, which I think is fairly normal and
healthy? I also have one filter sock that I change weekly.
<Well, since your tank seems to have a very low nutrient source, I am
thinking these could be Dinos (dinoflagellates), which prosper in the
absence of nutrients.>
Lighting... I have two Kessil 360's 8" off the water that run from noon to
10pm.
They start and stop with about a 90min blue and 0% intensity schedule, and
the 2hr ramp up/down period hits a peak of 45% intensity and sits there for
3hrs before dropping (7hrs all together), I'm adding 55% color on the same
schedule. I do get about 40mins of direct sunlight on the side of my tank
from a huge window, but I figure in conjunction with a 7hr light schedule
where I apply my color/intensity that this shouldn't result in my diatom
algae? Again, I ran the tank for a year algae free on a similar light
schedule (I wish I had kept the specs on that schedule – it was since
adjusted for various coral placement, etc.)
I remove all noticeable diatoms (that eventually start growing green hair)
with my water changes. I have conducted two full 3 day blackout periods in
the past two months, and still this all comes back.
<Worth trying a 5- day, to a whole week blackout, covering the tank with
cardboard and allowing no light at all, natural or artificial.>
I can't seem to figure this tank out. I was watching 52 weeks of reefing on
YouTube and the clean-up crew video where they indicated too many
snails/crabs can lead to algae because there isn't enough food for them all,
they die, and leads to excessive nutrients. What peaked my interest is that
I have thousands of those tiny little pebble snails (what are they called?).
<Astraea?.>
Could the birth and die-off of these little guys be causing a problem? Seems
unlikely
<Only if they die massively>
The algae starts only in certain spots, and then will slowly spread...
always starting in the same spots. My two return pumps each have a splitter
for two directional flows (4 total) and they circulate my tank volume maybe
15 - 20x/hour. Additionally, I have one MP40 on a random setting. I know
water flow will help with cyano, but it seems odd this diatom algae starts
growing right along the front of my tank in the path of my MP40.
Does anything stand out to you as a probable cause of this algae issue?
<Yes, from your description, and the way things happened, I am almost sure
these are dinoflagellates, which were introduced to your system via the
Chaetomorpha.>
With the algae starting on the bare rock and in the front of the tank where
it receives the most light, I keep going back to my lights. Thoughts?
Dave
<I suggest the following:
1- Trim your chaeto to about half and see if Dinos start to disappear over
the course of a week or two in the presence of some nitrates and phosphates.
2- Siphon out regularly the top layer of the sand, where the majority of the
algae is located .
3- A high ph around 8.4 seems to inhibit Dinos proliferation, I don’t know
your current reading, but it will help if you aim for the mentioned number,
go slow with any changes.
4- Leave only the blue lights on for 6 hrs./day, for one week (Dinos like
the white spectrum).
5- Consider adding a DSB to your refugium
6- If possible add a UV sterilizer.
I hope this helps. Wil.>

Does this look like Cyano to you? |
Re: Hi there from a fan, setting up my first saltwater
reef aquarium. 4/24/20
Thanks Bob. You are always so helpful and willingness to provide
guidance.
Well it looks like I’ve got good news. I might be able to fit a
5-foot system into my apartment, more swimming room is always better
than less. :)
<Yes, like a bank account balance, hard drive space, bigger IS
better>
I’ve decided not to mix Hawkfish species after my own research, I’d
rather not risk it.
<Okay>
Now with a 5-foot system (about 160 gallons) I’d be more confident
putting in a Zebrasoma Tang, but I’ve opted for a One Spot Foxface
instead because as a beginner I read on WWM that they’re a lot
“cleaner” in terms of diseases and parasites when compared to their
cousins, the Tangs. It’s also the only Foxface I feel comfortable
putting in because I would only opt for the Foxface Lo or other
species in a tank 6 foot and above.
<All right>
With the addition of the One Spot Foxface (I know a One Spot Foxface
or even a Yellow / Scopas Tang / Bristletooth Tang could work in a 4
foot system but it’s always better for the fish to give them more
room), I thought I would probably not make too many changes to many
original stocking plan. I know they’re a skittish fish at first, so
I thought I’d probably put them and my two Ocellaris Clowns as my
first fish.
Following that, I’ll put in my Marine Betta.
Then after that, my trio of Pajama Cardinals.
Then after that, the trio of Stripeys.
And finally, the two Flame Hawkfish.
Now, I know 12 fish really isn’t a lot for a tank of this size (it’s
really the maximum I can do), but I’d rather start off with fewer
fish of hardy species that make things easier to manage. I might opt
to add some other fish like wrasses, Basslets once my tank’s more
established and I feel more confident. And once my tank stabilizes,
a dwarf angel or maybe even a medium sized angel like a Xanthurus
Cream. Maybe a Tang, but I’m afraid that would be too much bioload.
I’d rather somewhat understock for
the first 6 months or so than have to deal with too many fish at
once. We all want the livestock under our care to be at the best
health they could possibly be, don’t we? :) That’s why I
want to take things slowly.
<A wise approach>
I’ve also selected my first six coral fragments, I’m trying to go
for a low maintenance, Mushroom and Leather Coral only tank. I’ve
considered Green Star Polyps and Xenia but they’re invasive, and
Zoanthids / Palythoas secrete toxins. I am aware that soft corals
use chemicals to fight each other for space and food, and that a
tank some point carbon may be required in my sump, but for now
perhaps regular water changes will do (10% every week).
The frags I have selected are:
An Orange Actinodiscus
A Blue Actinodiscus
A Yellow Devil’s Hand
A Green Toadstool
A Red Rhodactis
A Purple or deep blue Cabbage Leather
I’m not sure about the availability of these exact colors, but do
you see what I’m trying to do here? :)
<I think I do>
These frags I will try to get on average around 2” across, they’ll
be going in with my One Spot Foxface and Ocellaris pair. It seems
that medium flow and medium lighting throughout the tank may be fine
for them, from my research.
I apologize for another long reply, but as always I would appreciate
you taking the time and patience to let me know your thoughts.
You’ve been immensely helpful and I really appreciate the fact that
you’re taking time to correspond with me out of your schedule.
I am truly excited to be starting this journey.
With gratitude,
Andrew
<Beginnings are delicate times; first things first... DO get
the space ready (make sure it can support the weight evenly), start
thinking about live rock and not... BobF>
Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/24/20
Hi Bob, I was thinking today, do you think a Black and White
Bannerfish / Schooling Bannerfish / Red Sea Bannerfish (a single
specimen) would work in a system of my size?
<Better the former; but could>
I’m thinking of getting one instead of 3 PJ Cardinals but only if
they’re a hardier, more disease resistant and trouble-free community
fish compared to the PJ Cardinal.
<... hold off on all for now... Really, I'd just focus on getting
the tank up, going, putting in some initial organisms>
Which Heniochus species do you feel is the hardiest? Are they
suitable for the new system of a beginner?
Finally, as for a QT system, I’m afraid I may not have the room for
a QT in my current place. I’ve read your articles on several species
and it seems you feel that Captive Bred Clowns, Foxfaces, Stripeys,
Marine Betta and Roundheads in general, maybe Hawks and Cardinals
(what about the Bannerfish?) are exceptions when it comes to a full
QT regime.
I’ll definitely set one up as soon as I’ve got space for one, but my
LFS for now has said I can take my sick fish to them and help me
treat my fish.
I do, however, already have many medications such as Metroplex,
Focus, General Cure etc. ready.
Which species would you say most certainly need a full QT regime?
Just so I know when I try them in the future.
As always, I’d love your advice.
Andrew
Need help with a fish problem 4/23/20
Hi there,
I’ve got a problem with one of my wagtail platy’s. Well, I say problem, it’s
dead and I’m not that up to speed with bringing things back from the dead.
i woke up on Monday morning too see it was dead, but there was this huge
parasite looking thing coming out of it. I’ve called 5 different places and
they don’t really have an answers. Made an account on Fishlore.com to see if
they have any answers. They had none. But someone said I should email you
and see if you have any answers I’ve attached a picture to help.
I've been keeping fish all my life and I’ve never had this before.. all
parameters are fine and well within range.
it’s belly was bulging so I thought it was pregnant, I’ve had lots of fry in
this tank.
This thing wasn’t coming out of its gills or through its butt, it was come
out the side of the fish just behind the gills. It’s the black dot on side
of the fish just behind the gills.
I hope one of you lot can help me diagnose/identify what on Earth actually
happened, because I’m seriously stuck here. PS, I apologise for the fact the
picture was taken on an Easter egg box.. it was the first thing I had on
hand. Didn’t particularly want to handle it too much because a lot of
parasites can jump species
Cheers for reading, I hope you can help
<Evidently some sort of 'worm'. The problem is that it's hard to say whether
we're talking about an external parasite (which may not in fact be a true
worm, but a crustacean of some sort) or was this a worm inside the fish that
somehow got out through the wound. Very difficult to be sure without
actually having the fish in front of me, together with a decent dissecting
lens. In any event: certainly a good idea to treat your fish with
Praziquantel (such as PraziPro) or some other reliable anthelmintic.
Internal worms are quite common in livebearers, though rarely anything like
this. It's worth repeating the course after finishing the first course
because worms are difficult to shift. External parasites, particularly
crustaceans, are rare in aquaria and difficult to treat. Mostly, they can't
complete their life-cycle in aquaria, but some, notably Lernaea ("Anchor
Worm") can. Anchor Worms are distinctive because they have a dark, often
fork-shaped attachment head that digs into the flesh, as well as a
semi-transparent worm-like body that is visible outside the fish, often with
two egg-containing structures dangling even further. My gut feeling is that
we're dealing with something along those lines; if not actually Lernaea,
then some sort of crustacean external parasite. Cheers, Neale.>

Re: Need help with a fish problem 4/23/20
Hi there
<Niall,>
That’s absolutely fantastic! Thank you so much for your help, I’ll start the
treatment right away!
<Glad to be offer some tentative help at least.>
Goodness you guys are good.
<That's very kind. But do check your photos against pictures of Anchor Worms
and suchlike, and see if it is a plausible explanation.>
Well you’re definitely better than the 7 fish shops I’ve emailed and the 4
different forums I’ve posted on.
<Oh!>
Can’t thank you enough for that!
Thanks again!

Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/23/20
Would it be OK to mix Cardinalfish species? I’m thinking of mixing my Pajama
Cardinal trio with a trio of these red Cardinalfish (Apogon fleurieu?).
<... if there's room, decor/habitat... I wouldn't mix Banggais w/ other
apogonids in a four foot long system>
Furthermore, for my Stripeys, would a simple float acclimation of 1 hour be
enough for the ones I’ll get directly from the sea?
<Should, though quarantining them for a few weeks would be ideal. B>
Thanks Bob!

Re: Hi there from a fan, setting up my first saltwater reef

Would two trios of PJ Cardinals work in my tank?
<I would stick w/ a single trio here>
Two trips for six fish.
Thanks. My other fish will be 2 Clowns, a Marine Betta, 3 Stripeys, and 2
Flame Hawks.
Just curious. Is mixing Hawkfish species okay?
<Can be done; again given.... space, habitat. B>
Regards,
Andrew
Re: Hi there from a fan, setting up my first saltwater reef aquarium.
4/23/20
Dear Bob,
After some deliberation, I feel it could possibly be a good idea to stick to
only a trio of PJ Cardinals after all. They’ll either be the first group or
the second group of fish to go into my system. If a Marine Betta’s
available at my LFS, the Betta and my Ocellaris pair will be my first fish
in the tank.
If they don’t have a Marine Betta, the three Pajama Cardinals will be the
first fish in my tank followed by the Betta and the Clownfish pair (or the
Betta before the Clowns). My rationale behind this change is that I want my
slow-swimming, slow feeding fish to have time to adjust and settle into some
kind of feeding regimen before I add the fast Stripeys.
The Flame Hawkfish (or Flame Hawk pair) will go in last because they’re the
most aggressive fish, or if I opt for 3 Chrysiptera damsels (in which case
they’ll be the second most aggressive / territorial) the Flame Hawk/s will
be my second last fish to go in after the Stripeys.
What do you think of the Pinecone Fish?
<... an "advanced" choice; best for a "species tank". NOT for you here>
WWM does not have much info about it. I found a seller who occasionally
dives and collects these fish,
I think it’s the Monocentris japonica. Are they suitable for a beginner at
all? Thanks. It’s another interesting looking fish to me.
I would appreciate your patience as always.
On a side note, I’ve opted to go very easy in terms of corals. My tank will
be softies only, with only Mushroom and Leather corals. I find the Green
Star Polyps and Xenia too much of a threat because of their rate of growth.
<Ah good. B>

ADF Tadpoles 4/22/20
Hi Neale,
<Hanna,>
I am the worrywart who wrote to you about the lack of amplexus in my ADF
couple, which was clearly unwarranted concern, as a week or two ago,
they began doing exactly that.
<Yay!>
The male sings every night (and sometimes during the day too), and they
are seen engaging in amplexus almost every single day.
<Do bear in mind this is exhausting for the female. If you have one,
isolating the male for a few days in a breeding trap to allow her to
recover and feed leisurely would be welcome.>
There have been many clutches of eggs, the majority of which unfertile,
but two days ago, I found two tadpoles in their tank.
<Double yay!>
I had just previously completed a 50% water change, so I am guessing
much of the tadpoles were lost as a result of this, but I wanted to save
the two that I discovered left. They are currently in a floating
container in the tank with their parents, and are two days (at my best
guess) old. I know there is a huge ADF tadpole mortality rate (around
80%), but I would still like to try to keep these little guys alive!
<Understandable. Rearing baby amphibians (i.e., tadpoles) is mostly
about feeding them and/or preventing cannibalisation, which is quite
common in some species. In the case of ADFs, feeding is the main
challenge.>
I do not have liquifry, will I need to purchase this?
<No. What you need are small live foods. Microworms, brine shrimps,
Cyclops and Daphnia are the classic options. So long as you can get to a
clean pond somewhere, collecting a starter culture of these shouldn't be
too hard. Indeed, if you have a garden pond, you may well have enough to
keep you
going! Brine shrimps and microworms can easily be reared at home, though
you do need a few days to get them up and running.>
They are fairly active for being so fresh, and I put the tiniest pinch
of fish food into their container in the hopes that perhaps they would
be able to digest this is they were older than I suspected.
<They will almost certainly not eat flake or powder foods, since they
really only snap at moving things.>
Would you be able to give me any advice, or direct me to a page on
tadpole rearing for ADFs?
<Oh, definitely visit https://www.caudata.org and sign up to their
forum.
You will get good advice from those folks!>
Thank you so much, and hope you are staying safe! Best, Hanna
<And likewise to you, too. Neale.>
Re: ADF Tadpoles
Hi Neale,As always thank you so much for the incredibly prompt response!
<Welcome.>
As luck would have it, I have a creek in my backyard, and on my back
porch I actually have a few tanks full of spring peeper tadpoles. Per
your instructions, I used an eyedropper and selected about 6-10 tiny
micro-organisms that were swimming enthusiastically from these tanks (of
creek water), but small enough for the ADF tadpoles to eat.
<Can't imagine why this wouldn't work, but oftentimes best to pretty
much fill the tank with swimming plankton, since the tadpoles don't
really forage so much as wait for food to swim into range. Some
experimentation may be necessary, perhaps using a plastic dropper (like
a disposable pipette) to place food items close to the tadpoles. I rear
Axolotl fry periodically, and they need daphnia for the first few days
at least, and after a week or two, seem to graduate onto frozen
bloodworms without much
fuss. They are much bigger though, so I'd expect ADF tadpoles to need
the plankton for much longer.>
I hope this is alright, as I have not yet had the chance to peruse the
link you kindly sent me. If i continue this process every day for the
tadpoles until they are big enough to consume other things, will this
work?
<Should do. As with rearing any small newborns, the key is "small but
often" meals. Fish breeders often feed 6-8 times a day, replacing a bit
of the water each day as well, just to keep the conditions sweet..>
Thank you! Best,Hanna
<Most welcome.>
Black Sea Cucumber, fdg.
4/22/20
Hey Crew,
<Hey Joe>
I have enjoyed the info on your site and I have a question about my
Black Sea cucumber. I’ve had it for a couple of months. At first he
was hidden in the back of tank in between rocks and we barely could
find him. After a couple of weeks he became very active all moving
around tank ,constantly eating sand & pooping it out in big piles.
<These animals are mainly detritivores, but they also feed on
zooplankton and phytoplankton, requiring a well populated, mature
sand bed to get enough food. Could you please tell us more about
your system; water parameters, tankmates and maintenance routines?>
The last week or so it has taken to climbing up onto the glass.
<Perhaps it was looking for a more suitable spot.>
I’m worried that it’s not getting enough nutrients in the sand bed
of my 50 gallon tank & is doing this because it’s hungry.
<Probably it has consumed the available food source on the limited
sand area of your tank.>
I don’t want it to get stressed & nuke the tank.
<And they stress very easily... are you aware of the toxins they
release when stressed? I have witnessed one of these echinoderms
wiping out an entire, well stocked 1000-gallon tank in just a few
hours!>
Is this normal or should I be concerned. Please let my know what you
think and if I should try bury some food in sand. If so what type of
food.
<Do you have a sump/refugium?... if so, there you can grow small
organisms like copepods and amphipods to provide a constant food
supply for your cucumber, you may also try some frozen or dry foods
like Cyclop-Eeze.>
Thanks for any advice/info you can give me.
Best Regards,
Joe Matranga

Corydoras slowly dying off one by one, no one has
answers. 4/22/20
Hello. I am reaching out to you with a very strange problem that no
one else seems to have any idea on what it could be.
<Understood.>
This involves my Bronze Corydoras, who all came from a clutch I
hatched in June of 2018.
<Well done on the breeding, by the way!>
Before I go into the details of the problem, I'll do the important
housekeeping of tank parameters. It's a planted 75 gallon, set up
since February 2019, with plenty of caves and nooks for hiding.
Substrate is a
fine gravel that they have no problem with, all have full bellies
and long barbels.
<Still, as you seem to recognise, not ideal.>
Tankmates are 2 adult Bronze Cories, 4 Peppered Cories (I need to
get more) and 15 Cherry Barbs.The problem has gone on for a long
time though, so it is unrelated to tankmates.
<And Cherry Barbs are lovely fish that shouldn't cause any
problems.>
Ammonia: 0ppm Nitrite: 0ppm Nitrate: 20ppm pH: 7.8-8.0 (I added
driftwood yesterday, so this might change in the future.) Temp:
74-76F
<A little on the warm side for this/these catfish. Peppered
Corydoras especially are low-end tropicals, even subtropicals, and
thrive if given a cooler winter period. Around 18-22 C/64-68 F is
ideal. Supposedly, wild fish can be found swimming under the ice on
rare occasions! Bronze Corydoras are not quite so fond of cold, but
still, I'd be keeping things towards the cool end of the range,
maybe 22 C/72 F, and providing plenty of oxygen. Yes, the species is
very adaptable, but if you're struggling with a
certain species, sometimes going back to basics, and seeing what
"ideal conditions" would be can help, at the very least, in the
dismissal of factors that aren't to blame.>
GH: 8-12 KH: 4-6
<Wouldn't expect much of a pH change with this much carbonate
hardness, assuming regular water changes.>
Water changes: Weekly, 20%-40% depending on what is needed.
Filtration: Marineland Penguin 200, Cascade 1000 Canister filter, a
sponge filter
<All sounds fine, but how much water movement is at the bottom of
the tank.
Put some flake down. Does it sit there? Or flap about weakly? Or is
it quickly whooshed away in the current? Remember, slow water
movement at the bottom of the tank means low oxygen levels. Not an
issue for midwater barbs and tetras, which swim into strong water
currents instinctively, and so get
more oxygen. But benthic fish, such as catfish and loaches, may
struggle.
Sure, they can swim to the surface to gulp air, but that's not
something most species are meant to do all the time, and indicates
they're under a degree of stress.>
Treatments: Seachem Prime, Aquarium Co-op EasyGreen Food: Once a day
feeding of any combination of Hikari Sinking Wafers, Omega One
Catfish Sticks, Omega One Sinking Pellets, and Hikari Micropellets.
Once a week I feed thawed frozen Brine Shrimp and Bloodworms, Omega
One brand. Occasional treat of blanched veggies for them and the
Cherry Barbs.
<All sounds fine.>
None of the other Cories have developed this, just these siblings.
The symptoms are always similar. The Cory becomes lethargic, looses
its appetite, and breathes rapidly. They often become dark in color
and
sometimes, but not always, their eyes cloud over and they loose
vision.
They never live for more than a few days after the symptoms first
present.
It only ever effects one Cory at a time, and there's always a period
of time between one showing symptoms. I don't believe it's related
to water quality or diet, their foods have plenty of Vitamin A and
I'm diligent about keeping things clean.
<But do see above re: water movement and oxygenation. If midwater
fish are healthy, but you're losing benthic fish, that's a good clue
there's something amiss "down deep" and your attention should be
directed there.>
I've speculated that this is some sort of genetic problem. Their
parents were chain pet store fish, and though their mom has always
been very healthy, their dad was not the most robust, and he passed
away without any cause or symptoms not too long ago.
<That can certainly be an issue, but if genetic, you'd expect to see
deformities from the fry-stage onwards. While poor genes can indeed
mean a weaker immune system, again, you'd expect to see this from
the get-go, not months or years later. So while certainly a
possibility, it would not be my first choice for an explanation.>
The fry did not have a good survival rate, and there were genetic
abnormalities noticed in some of them as they got older. (Mainly,
some of them developed very long fins, and all of those died from
this condition.)
<Long-fin Corydoras are "a thing" in the trade, and yes, the
inbreeding does make them a bit more delicate. Usually they're more
prone to Finrot and other such afflictions of fish easily damaged or
nipped.>
They also are slow growers, at nearly 2 years old they are nowhere
near adult size.
<Odd.>
I'm down to 11 from over 30 juveniles that grew big enough to put in
with the adults, most of them dying from this issue. I have yet
another one who started showing symptoms last night. This Cory was
absolutely fine the day before.
<Not good.>
At different times for different fish I've used Furan-2 and
Amoxicillin in a 10 gallon quarantine tank. The fish always died
overnight or the day after treatment. I have tried quarantining some
of them and treating them with antibiotics, because the symptoms
show some similarities to a bacterial infection, but they always die
within a day or two of starting treatment. It seems like whatever
this is, by the time symptoms show they're too far gone to treat.
<Understood.>
I'm at a complete loss here, I've asked other places and no one has
any idea other than complete shots in the dark. This has been very
hard to deal with, and I feel completely helpless. If anyone has any
idea what this could be, or knows someone who might, please let me
know.Below are images I've taken over the course of many months, in
chronological order. Each one is of a different Cory who had this
condition, the last one is currently suffering from this. The first
one is one of the long fins I mentioned
earlier. I'm linking them because the images are very large.
<Appreciated.>

<Adam, my instinctive feeling is there's something
environmental going on here. Get back to me when you've
done the flake test on the substrate. If the water is rather still,
I'd go with long-term oxygen stress, which combined with the higher
than ideal temperature, could make the fish more
prone to opportunistic bacterial infections. I mean by that your
fish are almost certainly dying from something like a Pseudomonas,
Aeromonas, or Mycobacteria infection, but all of these are latent in
even the best aquarium, and only cause problems when the fish's own
immune system is compromised. Mycobacteria infections are
notoriously difficult (i.e., impossible) to treat, but then again,
even the more easily dealt with Aeromonas infections aren't going to
go away if too far gone or the environment keeps the fish under
stress. Cheers, Neale.>

<<Hi Bob! When you paste this up, can you add any thoughts of your
own? I'm very open to ideas here! Neale.>>
<Sure; have read over, incl. your reps. First I would ask Adam to
"check the checkers", to make sure the test kits (particularly
ammonia and nitrite) are accurate. When the aquarist stirs, disturbs
the substrate, do gas bubbles erupt? Is there a soil substrate
mixed, in place? Are they using a liquid plant supplement?
Foodwise, I'd skip the bloodworms entirely and the blanched
vegetables for now.
I too suspect the cause of these losses as environmental, perhaps
with a genetic component.

Yellow-Bellied Slider Turtle 4/22/20
Me and my fiance noticed a spot on the top of the head of our yellow-bellied
slider and were unsure what it may be. We need to know if it's something
that can be handled naturally or if we may need to see a vet. I've attached
a picture of what it looks like.
<Hello Ethan. This looks to be an ulcer of some sort. Somehow the skin was
damaged, and a bacterial infection has set in. 'Dry Docking' the turtle will
help (see elsewhere on this website) and you can carefully use medical
iodine solutions (such as Betadine) to clean these wounds once the skin has
dried off a bit. After the wound has healed, which may take some days or
weeks, he can be returned to his normal environment.
http://www.wetwebmedia.com/FWSubWebIndex/treating%20RES%20Dis%20DarrelB.htm
That said, if you're taking this chap to the vet -- which is an excellent
idea -- your vet will give you a suitable treatment to follow. In the
meantime, do try and review the turtle's world to see why he got damaged.
Aggression between turtles is one possibility, sharp objects in the tank
might be another. Check also that family members are handling him right, and
that you don't have any pets (like dogs) that can somehow get into his... (?
the end. RMF)

Re: Hi there from a fan, setting up my first saltwater
reef aquarium. 4/22/20
Thanks Bob. No Soapfish for this setup then. Even though you said
the risk is small, I’d rather not have to deal with their toxin (not
for this setup) and I’d rather give it more room. If I ever think
about getting a Barred Soapfish again it’ll be for a tank at least 5
or 6 foot long (or maybe even that’s too small?).
I’ll stick to a trio of Pajama Cardinals, get them small, and
otherwise sick to my original plan with the Marine Betta, Clowns,
Cardinals, a trio of Stripeys, and some damsels for my 4 foot
system.
I appreciate all the help you’ve given me.
Sincerely,
Andrew

I did learn something useful though, which is to transport fish by
putting the bag horizontally rather than vertically. I’ll definitely
keep that in mind!
Is there anything to keep in mind when collecting the Stripeys from
the coast near me? I’ll be going for the smaller ones that are 4-5
cm. What kind of net and bag should I use to capture them, and how
do I acclimate
fish that I caught on my own to my tank?
<You'll likely find a fence/barrier/mist net useful... can build or
buy one... with a float and lead lines. See WWM re>
Would these fish be at particular risk to any diseases or parasites?
I don’t want them (the diseases or parasites) entering my system.
<Not likely>
Also, would my Marine Betta and Hawkfish have trouble competing with
them for food?
<Could be in time>
How do I make sure the slower fish are well-fed in the presence of
the Stripeys?
<Search, read re on WWM>
Thank you Bob and once again I’d appreciate your time and patience.
Regards,
Andrew
Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/21/20
Finally, Bob. Sorry to bother you again. What would be the expected
lifespan of these Stripeys in captivity? Thanks.
<Don't know... likely years>
Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/21/20
Never mind about collecting my own Stripeys or other fish in the
future. :)
I found the article on WWM. Would appreciate you taking the time to
answer my other questions though. :)
Regards,
Andrew
Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/21/20
Thanks Bob. If I get 3 or 5 Pajama Cardinals, will they likely be
aggressive towards each other, resulting in attrition?
<It's a possibility.. hence starting them small/ish and as a trio>
If I keep them with some damsels, would the damsels cause them any
trouble?
<Not likely, but depending on the damsel species, they can be the
same way w/ each other. >
I came across this fish called the Barred Soapfish on WWM. It looks
pretty cool. However, do you feel it would be suitable for my 4 foot
system? I’m imagining it’s a big but fairly sedentary fish like the
Comet,
though I could be wrong.
Can it be trained to eat flakes, frozen foods and pellets?
Is it very hardy, disease-resistant and long-lived? I’m worried
about their poison but, according to WWM they rarely excrete it.
<Am not a fan of Soapfish species in small captive systems. Bob
Fenner>
If I can include that Soapfish, my build could possibly be:
x1 Marine Betta
x1 Barred Soapfish
x2 Ocellaris or Black n White Ocellaris Clowns
x1-2 Hawkfish
x3 or 5 Pajama Cardinals
Thanks!
Also worried about the Barred Soapfish eating my smaller fish (does
that usually happen?) and having a big bio-load.
Oscars 4/21/20
Sent from my iPhone hello my name is Jeannie my husband has Oscars and he
changes the water frequently It looks like the Oscar has a protruding anus
as of what I was told my husband feeds them Oscar pellets and they were
fine.
<Correct. This is a prolapse, and Oscars are more prone to these than most
other fish. Partly it's their size and the difficulty people have ensuring
the right water quality, and partly it's their need for a much more varied
diet than some people imagine. Let's pick both of these apart. In terms of
care, Oscars need a large (100+ gallon) aquarium with robust filtration
(water turnover rates of at least 8 times per hour). Water changes should be
weekly. You're aiming for 0 ammonia, 0 nitrite, and, crucially, nitrate
levels below 40 mg/l and ideally below 20 mg/l. All cichlids are sensitive
to nitrate, but unfortunately big, messy fish will raise nitrate levels very
quickly. Having a big aquarium helps dilute nitrate, which is why the 55-75
gallon tanks often recommended in the past for large cichlids don't really
work in the long term -- at least not without much more frequent water
changes. As for diet, Oscars are omnivores in the wild, consuming small
fish, insects and crustaceans as well as fruits and the usual organic
detritus most fish will nibble on when bored. So while something like Hikari
Cichlid Gold makes an excellent staple, it should be augmented with, in
particular, sources of roughage to keep the digestive tract in good health.
Cooked peas are a good choice, with most cichlids eating them when hungry
(feel free to starve them for a week or two if needed) but suitably
gut-loaded insects and crustaceans work well too. Frozen brine shrimp with
added Spirulina are good, as are small crickets. Earthworms are a superb
choice if you have access to a clean supply of them. The foods to avoid are
anything with fat (chicken and beef, for example, though beef heart, using
sparingly, is fine) as well foods known to be unsafe (feeder fish and
Tubifex).>
I seen this happen after he changed there food please tell me what I can do
to help the Oscar get better.
<Three things to do. The first is to add Epsom Salt to the water. This is
NOT the salt we use in the kitchen, but easily bought online or in
drugstores. Use 1-3 teaspoons per 5 gallons/20 litres. What this does is
work as a mild laxative. Secondly, stop feeding for a week. This will do no
harm to any of the fish in the tank. This gives the digestive tract some
time to recover. And finally, after a week, introduce sources of roughage
into the diet, and only use those foods -- no dried foods or pellets! --
until the fish recovers. Do, of course, check water quality. If you don't
see any signs of improvement, medicating with Metronidazole and an
antibiotic may help, as this combination is widely used with cichlids where
we're dealing with unknown parasites and pathogens.>
He was feed them cichlids gold for about 2 years and about 1 month or 2 ago
he changed it to jumbo minis and that happened
<Hope this helps. Cheers, Neale.>

Fish QT question 4/20/20
Hi Bob and gang,
<Hi Danny>
I learned my lesson (the hard way) a few years ago and set up a
dedicated 29 gallon quarantine tank in the basement. It’s made a
huge difference.
<It certainly does!>
My question is this. After a few days, when the fish have settled in
and are eating, would you advise beginning a prophylactic copper
(Cupramine) treatment even if the new fish don’t show any signs of
Crypt or Velvet? Or would you treat with copper only if they show
signs of disease?
<I would not treat unless there are visible signs of disease, I
suggest watching your fish for a couple of weeks and if everything
is fine, just move them to the DT, perhaps just giving a 5-min FW
dip/bath (temp/ph adjusted). Cheers. Wil.>
Thanks,
Dan
Re: Fish QT question 4/20/20
Makes sense. Thanks a bunch!
<You're most welcome. Wil.>
Re: Hi there from a fan, setting up my first saltwater
reef aquarium. 4/20/20
Thanks Bob! I don’t think I’ll get it for my tank as I already have
a Marine Betta as the large fish. I’ve decided to go with the 4 foot
tank and I found out that I can collect these Stripeys really easily
from the coast
near where I live (southeastern China).
<Neat!>
My new stocking list will be:
x1 Marine Betta + x2 Ocellaris / Black and White Ocellaris Clowns
(First
group of fish to go in)
(Wait a couple weeks)
x2-3 Stripeys
(Wait a couple weeks)
x3 Pajama Cardinals
<These may have a hard time competing for food w/ the Stripeys>
(Wait a couple weeks)
x1-2 Flame Hawkfish
Will this work? Will it massively overstock my tank and impact the
bioload?
<Should be fine. B>

Thank you very much, I will try my best! Tilting this tank is a
whole project in itself.
<Mmm; thought about this; yeah. Tilting up a ten foot high tank...
Maybe just on the edge will do; be better than just vertical>
Would you recommend Weldon 16 with a high gauge needle for this?
Thanks again, Anthony
<Yes to the #16 and small gauge needle. It REALLY flows into small
gaps. Bob Fenner>
Bolivian Ram bottom sitting and not eating after being shipped to
me. Pix 4/20/20
Good afternoon, I write to ask for help! Bolivian Ram that I recived 2 days
ago in shipment is not dooing good.
<I would immediately claim this against whatever insurance policy the online
retailer provides. While this fish may recover with appropriate treatment
(i.e., Metronidazole along an antibiotic) and good conditions, it
is in a very bad way. Cichlids do become stressed when exposed to cold, and
can recover if kept properly afterwards. But this fish looks very thin and
dark, so there may be something else going on.>
Fish is sitting on the bottom, not reacting to food and struggles to swim
from time to time with its tail down. Shipping took almost 2 days. My tank
is established for 11 weeks now. I house In it 7 Honey Gouramies, 2
Bolivian Rams, 5 Panda Cory's. It is 29 gallon planted aquarium with
Canister and HOB filtration. I use heater, air stone and LED lighting.
Bolivian Ram that I did recive looks mature, fish is big but I don't know
how old it is?
<Likely 6-12 months old if this is a farmed fish sent out to you not long
after being received by the retailer from the wholesaler.>
Please help me to bring it back to life. Should I use aquarium salt for few
days?
<No.>
Will it help?
<No. Good luck, Neale.>

Re: Bolivian Ram bottom sitting and not eating after being
shipped to me. 4/20/20
Thank you for your response Neale,
<Welcome.>
I've just ordered Metronidazole for fish.
<A good call, and the best general purpose cure for cichlids because they
are so prone to things like Hexamita that only Metronidazole will treat.>
I hope that my Bolivian Ram will make it. There is no chance to get any
response from the farm I did order my fish. I tried already...
<Oh dear.>
I just have one more question about it's gender. I did order boy but this
fish looks like female to me. Can you confirm it?
<Not from your photos, no. This species is quite difficult to sex. Males and
females are almost identical, with only a few differences: males are
slightly bigger, tend to be slightly more colourful, and have slightly
longer fins (especially the tips of the dorsal, anal and tail fins). Beyond
that, younger specimens of both sexes can be easily confused. Cheers,
Neale.>

Need help to identify a worm 4/20/20
Hi,
I found a worm outside of my house, just near to my dog, when I accidentally
step on it. After looking it I found this so weird because it is first time
i have ever see worm with glowing blood. I have attached pic
of it, with flashlight and without flashlight. Is it baby millipedes? So
confused.
<Hello. That's quite the find! It appears to be a polychaete rather than a
centipede or millipede. I say that because the body appears to be soft, with
no obvious exoskeleton, unlike those two arthropod groups. A
polychaete ('bristleworm') seems more probable than an oligochaete
('earthworm') because of the fleshy appendages on each segment. However,
terrestrial polychaete are very rare, unlike oligochaetes, which include
numerous terrestrial species. So my guess in the absence of any other
information would be that this is a marine polychaete, perhaps dropped by a
bird onto dry land somewhere near your home. Of course if you live near the
sea, this makes sense -- but if you're more than a few miles inland, that
would be an unlikely explanation. There are freshwater polychaetes, but
they're mostly quite small and unobtrusive, and not at all common.
Fluoresce in polychaetes is quite well documented, though again, to the best
of my knowledge only among marine species. Better photos of the head end of
the animal would help -- polychaetes usually have obvious jaws complete with
sharp pincers in many cases, as well as eyes and tentacles, all of which are
absent from most oligochaetes. It would also help to know where you live. In
the Southern Hemisphere, velvet worms might also be considered, but you
wouldn't find these in Europe or North America, and again, they only live in
specific habitats such as rain forests. Cheers, Neale.>

Copper Banded Butterfly changing appearance...
4/20/20
Hi gang,
<Hey Chuck>
I have kept a copper banded butterfly for 3+ years in my macroalgae
display tank (connected via common sump with my reef tank)
<Chelmon rostratus is not one of the easiest BF species to keep; it
requires top water quality and a varied diet.>
... it's a low intensity tank, with just a juvenile scopas tang for
company.
<What are your water parameters?>
He feeds almost exclusively on frozen mysis, and whatever else he
gleans from the seaweed.
<This diet is not varied enough.>
Recently, the gold vertical stripe underneath the 'false eye' near
the tail has started going dark... almost black. It's symmetrical on
both sides of the fish. No signs of trauma... appears to be a
pigmentation issue. Is this a sign of stress... or advancing age...
or anything else you can think of?
<Not because of advanced age, no... these fish can live up to 20
years. I think this is more environmentally stress related.>
Thanks in advance for any help on this...
Blessings,
Chuck
<Cheers. Wil.>
Re: Help Bob Fenner; PBT
4/19/20
Hi Bob, sorry to bother you again. This has gotten me nuts. She looks
twice as worse since putting her back in my main tank. Although the
water that was in my qt came from my display....its not the water
irritating her..I’m assuming. I give up. She’s now %85 covered in those
lesions.
<Do send along another pic. Do you have, use purposeful cleaner/s?
Cleaning organisms...?>
Hiding and swimming erratically. I’m having a hard time just watching
her get slowly worse. Should I remove some fish?
<Maybe... do you have another established system to place this fish? IF
NOT, DO change all the water out of the quarantine and refill it, do
daily water changes (20-25%) with the main/display system water>
I’m pretty sure the three Anthias I last added are the contributing
cause for her stress. I’m at a loss.
<Cheers, BobF>
Re: Help Bob Fenner; PBT
4/19/20
Here's a great pic. Are you saying put my PBT back into qt?
<Yes>
Using my main tank water? And doing daily waterchanges?.
<Yes and yes>
If I'm using my display water for qt water changes...isn't the water in
qt staying the same? I was going to pull the 3 Anthias and take them
back to my LFS. Something in my main display is Stressing her out.
<Can you tell what it is... the fancy bass?>
She was fine before adding the three Anthias. I do have a decent
CUC...if that's what your referring to. She looked so much better in Qt.
<BobF>

Re: Help Bob Fenner 4/19/20
<Please change the title of your emails... they're all going to our "Junk"
folder... Just Re: PBT will do>
3 Anthias square backs. One male and two females. Should I treat with
anything once she’s back in? Or just water changes?
<Just the water changes, though I'd drop the spg a few hundredths... will
make it easier for the fish to breath, shed mucus>
I went through a 5 day treatment of Maracyn already...and was going to do
that again, until you told me to put her back in.
<I'd skip any antibiotic administration. BobF>

Acrylic Repair 4/19/20
Good morning,
<Anthony>
I wanted to reach out and thank your whole crew for helping organize a lot
of great information on this site!
<Ahh! Thank you for your kind, encouraging words>
I recently purchased a used 1200 gallon 10x4x4 with 1.25” acrylic walls.
<Mmm; I'd rather 1.5" material...>
It was on a horribly uneven and rusty stand,
<Yikes>
but still holding water, and I’m worried about this one seam on the tank
along the top center wall.
<I see this "white out" area in your pic>
All the other seams hardly have a single bubble, and it’s on a new level
stand. Can I just use Weldon to strengthen this top seam if all the other
seams are near perfect?
<This is what I would try... tilting the tank so the open slit of the seam
is facing upright, putting some sturdy tape along the panels to disallow the
wandering of the low viscosity Weldon, saturating the gap, allowing the
solvent to fill this area... waiting a day to see if this has helped
sufficiently>
Thanks in advance,
Anthony
<Certainly welcome. Bob Fenner>

Re: Hi there from a fan, setting up my first saltwater reef

Thanks Bob, as always. You always give great advice and info. Would you mind
helping me ID this fish? I can’t seem to find it anywhere. Once again, I’d
really appreciate it.
<Oh! Appears to be a Nemipterid; likely Scolopsis vosmeri (Bloch 1792), the
Whitecheek Monocle Bream.>

Re: Hatchling Eye 4/18/20
Thank you so much for your help ,
<Most welcome.>
I think I will see the nearest vet.
<Good call.>
Would you recommend eye drops until I can get him there?
<If sterile, possibly. But if a vet is taking a look, perhaps best to
wait.
There are specific eye drops for turtles available, and these should be
safe. For example, Zoo Med Repti Turtle Eye Drops which retail for
around $5-10. I would not use human eye drops without checking with a
reptile expert or vet first. Cheers, Neale.>
Re: Guppy colony issues
4/18/20
Thanks so much Neale,
<Welcome.>
I medicated them again with Prazi per the instructions.
I notice his tail is whitish on the ends does that make fit rot or
nipping more likely?
<Finrot. But the two are often linked. When the tissue is damaged,
any dead tissue goes white. If blood vessels become congested, they
may turn pink or red, and this is often a good sign you're dealing
with Finrot. Because repeated nipping makes fish vulnerable to
bacterial infections, there's a link with Finrot (which is a purely
opportunistic, and not a disease that you can stop from getting into
a tank).>
Its 70L I was supposed to sell or give away half of them but
couldn't due to corona virus.
<Understood. Do keep on top of water changes, do ensure aeration is
good, and do avoid overfeeding.>
I could remove all or most of the rams snails to help as there is a
lot. I add rift lake cichlid salt to the tank
<Snails won't make much difference so wouldn't be too bothered about
them.
Cheers, Neale.>
Re: Help Bob Fenner, PBT
4/18/20
Hey Bob, I forgot to ask this before. These lesions that did not
come off in a dip are still very much attached to her. She’s not
looking much better than when I first took her out. Obviously this
thing is not life threatening right now. I’m continuing to soak her
foods and monitor. In your experience with this, will she heal from
this? And how long can I expect her to be like this?
<Likely will heal in time, weeks to a few months. BobF>
High nitrate levels in pond and aquarium
4/18/20
Hi Bob and Friends,
<Hello Annette.>
Recently my platys have been dying. All my other
fish seem ok. I did a water test kit from API and the pH was 7.6,
but the nitrates were at 160 ppm, which was the
highest level.
<Yikes! That'd be the reason. Fish vary in response to nitrate.
Cichlids and Mollies are very sensitive, and long-term, anything
above 20 mg/l can cause health problems. Most community fish will be
fine up to 40-50 mg/l, and characins and catfish seem to be, on the
average, among the least sensitive fish (which probably explains why
they were old favourites for community tanks up to the 1970s, when
people avoided water changes).
Platies are likely to be more like Mollies, so your high nitrates
could easily be the problem.>
Is there anything I can do?
<First up, a water change. Do a series of changes across the next
few days, such that you change 30-50% of the water each time. Try
and keep water chemistry and temperature steady. After a few days,
nitrate should be close to whatever your tap water level happens to
be. Secondly, review stocking, tank size, and feeding. The old rule
that says "an inch of fish per gallon" is pretty good, so if you
had, say, 10 platies, these are about 1.5-2 inches long, so you'd
need 15-20 gallons to keep them. Any additional fish would be added
to that, so if you had, say, six Corydoras catfish, each about the
same size, they'd be another 9-12 gallons, so together your tank
would need to be at least 24-32 gallons in size. This rule is
conservative, but works really well for small fish in the 1-3 inch
size range. Feeding should be moderate, and as a rule of thumb,
small community fish need a 'portion' of flake about the size of
their eyeball each meal. Feeding once or twice a day is fine, and
for fish like Platies especially, just letting them graze on algae
(or softened vegetables, such as spinach, peas or
cucumber) is a fine way to round out their diet. Overfeeding fish
doesn't kill them by poisoning them or blocking their stomachs or
something, but too much food does mean the filter is working harder,
and as you can see, the end product of filtration, nitrate, isn't
non-toxic. That's why we do water changes every week or two: to
dilute that nitrate. Fast-growing plants (such as floating plants if
you have indifferent lighting) can be
really helpful too, since plants absorb nitrate.>
The pond was the same. I saw a De-nitrate water additive.
<Don't waste your time with additives. Water changes do a massively
better job, for much less cost. Honestly, while there may be niche
applications where denitrification is relevant to freshwater
fishkeeping, there's
otherwise no reason to get bogged down in this side of things.
Instead limit stocking, ensure the tank is nice and big, don't
overfeed, and do regular water changes. That's all you need to do,
and it not only works well, but doesn't cost anything!>
Annette
<Cheers, Neale.>
Golden Apple snails (and goldfish)
4/18/20
I have been enjoying the section about the Apple snails,
and it has been helpful especially in regards to calcium levels and
possibly supplements.
<Glad you've enjoyed!>
Over 7 years ago (I am not sure of the time span so it may have been
longer) I acquired a Golden Apple for my 50 gallon goldfish tank on
my patio. I named it Grover and it was the first Snail I ever liked.
(I live in California USA where the escaped escargot has not only
adapted well but is a bit of a pest for rabid gardeners like myself,
so I wasn’t able to Ohh and Aahhh over them and call them cute).
<Well, they're native here in England, or at least the very similar
and equally edible Helix aspersa is, and my cottage garden is
infested with them! They're interesting animals though. And Escargot
snails are very delicious! Or perhaps it's just the garlic butter?>
Grover, however, was not only very attractive in color, but
fascinating to watch. “He” and the 2 standard goldfish lived well
together, neither bothering the other in any way. I knew about how
to care for the goldfish but never even thought about finding out
about Apple snails. I guess I just figured that he was a snail and
would be as adaptable as all the other water snails I ended up with
no matter how I tried to clean new living plants before adding to
the tank.
<Alas, Apple Snails can be problematic. There's a range of species
and hybrids out there, which means some people find them easy, and
some people not so much. The average specimen lasts maybe a year or
so, but I've seen some specimens that were many years old and almost
the size of tennis balls.>
I had a plethora of “pond snails “ (small almost rounded brown
snails), the larger rounded snails and lastly the darn trumpet
snails which polished off all the other snails and took over.
<Now hold on a cotton picking moment! Melanoides snails need some
decent PR, and I'm the guy. Yes, they multiply rapidly if there's
lots for them to eat. But they are detritivores, and will not ever
kill live snails or healthy plants. Indeed, if you can see them at
all (at least during the daytime) there's something amiss because
naturally they hide in the sand during the daylight hours. If you
see them on the glass, especially near the top of the tank, during
the daytime that means they're coming up for air, and that in turn
means there's something wrong with the substrate and/or water
column. They're the miner's canary in that regard, being the first
sign of trouble.>
Took me years to get rid of them.
<Indeed; Melanoides are best controlled rather than eliminated.
Individually, they're short lived, and in tanks with minimal algae
and organic muck, their numbers should stay low.>
I had 5 indoor tanks of various sizes indoors and 2 tanks outside.
The weather allowed me to do that. The only problem was the
expletive deleted raccoon that raided my smaller 10 gallon and ate
my bristled nose Pleco early Thanksgiving morning.
<Brutal.>
Grover lived to become almost as big as a baseball and died at
approximately 5 years of age.
<That's actually not bad at all! Five years is a good age for an
Apple Snail. They rarely get that old without a cooler/warmer cycle
through the year, so a patio or conservatory tank at ambient
temperature is likely better than the usual indoor tropical tank
that's kept constantly warm.>
The goldfish lived 7 years and would have lived longer if we hadn’t
gone on vacation and left my cousin in charge.
<My advice with fish is, unless you're gone more than 2-3 weeks,
just leave them unfed. Fish can go weeks if not months (in the case
of big fish) without food. But overfeeding and the resulting water
quality crash has killed many, many pet fish over the years.>
Grover and the fish (I kept on changing their names but nothing
settled) always knew when feeding time was, and I still remember
watching him come up to the water line and put his foot thingy up to
catch flakes with. I used to also feed him algae wafers and
zucchini.
<Sounds good.>
That all being said, tank care is a lot of work so I am now down to
one 70 gallon tank and my Corydoras finally all died off, so I
bought 5 Golden Apples. I bought 5 in order to attempt to insure a
good population level and in hopes that they would clean up the
algae.
<They can do, but they're more plant-eaters than algae-grazers.
Certainly when compared to, say, Nerite snails, which eat nothing
but green algae and diatoms.>
They have been very busy. I have 6 or 7 egg clutches that I can see
on the glass, and I have seen them in the midst of their snail
orgies for days. Who knew snails would get that horny.
<They will certainly breed readily given the right conditions. Eggs
need to be above the waterline to be viable though. Often laid on
the aquarium hood or, if you're going for the _au naturel_ approach,
vertical plant stalks and leaves that stick out above the
waterline.>
I seem, however, to be missing 2 of them.
<Broody Apple Snails will leave the tank if they can to find a
suitable egg-laying spot. In the wild they ascend plants anything up
to about a metre above the waterline, and once the eggs hatch, the
baby snails drop into the water below. Unlike your dratted Helix
pomatia, which have a strong homing instinct, Apple Snails easily
get lost. Look around the back of the tank, anywhere dark and
hopefully damp. Apple Snails can survive out of water for some days,
provided they don't dry out.>
I had added some little calcium ball things to the tank, but I
haven’t checked the parameters of the water yet. Couldn’t find the
test kits. I expect the new test kit to arrive tomorrow! I also
noticed the 2nd clutch is gone and I have a lot of little snails in
the tank. I am really not sure what type of snails they are. The
shape of most of the shells look like the Apples, but some are
brown, some gold, and others are white. So I am worried about that,
too?
<No, quite normal. I fed my baby snails on floating lettuce leaves,
which they enjoyed.>
Snails can remain dormant for some time. In addition, many of the
small snails accumulate on the filter intake tubes. I think I
resolved that problem by placing cleaned window screening over the
ends and securing those with a rubber band.
While doing that in the midst of cleaning the intake tubes, I
removed a long stream of what appeared to have been a snail head and
feelers. Argh. Yesterday I noticed a Golden Apple with no apparent
head that I could see, and it was covered with the little snails who
looked like they were eating it. I picked it up and shook 98% of the
snails off, but it appears to have closed its door way, so I put it
back in the water in a different place. Today I saw a portion, about
an inch, of it slid out from the shell and covered with many of the
smaller snails. I am afraid that they are eating it.
<Apple Snails, like most snails, are opportunistic, and if a snail
is dying, may try to feed on it. It is wise to remove ailing snails
at first sight, and either humanely destroy them (sticking them in a
bag and in the freezer will do this) or quarantine them for a few
hours or days in something like a large plastic tub so that you can
see if they're dead, alive, or somewhere in between. Our
understanding of snail healthcare is rudimentary, to say the least,
but sometimes isolating sick snails for a few days allows them to
get better under their own steam.>
They don’t have the striped coloring of the assassin snails shown,
so I am really not sure what they really are. I thought that they
were either golden Apple snails just not golden yet or possibly a
form of previously dormant pond snails. The week before last there
were at least 4 Golden Apple snails.
Questions as follows:
1. What are the best KH, PH and Nitrate ranges for Apple snails ?
<They are not fussy, but I'd tend towards moderate hardness and a
slightly alkaline pH; say, 10+ degrees dH, pH 7.5 simply to avoid
pitting in the shell. Nitrate, as per fishkeeping, should be below
50 mg/l, and ideally below 20 mg/l.>
2. What would you recommend to use to supplement the calcium level
in the water?
<No real need in hard water unless you have a lot of snails. Look
for signs of pitting on the shells. If present, then yes, extra
calcium would be a plus.>
3. Is it normal for snails to eat each other IF one is dead, or do I
have a problem here?
<Yes, normal; whether problematic depends on the causes, but as I
say, remove ailing snails regardless.>
4. I need to do another tank cleaning water change anyway, so I can
just vacuum up most of the little snails if I have to. Do I need to
do that?
<Yes, as with any breeding project, the more small water changes you
do, the greater the numbers of offspring you will rear.>
5. Do you need photos?
<Not especially but feel free to send some along if you'd like to
share. But do try and keep them to below 1 MB in size.>
Thank you
Amy O.
<Most welcome. Cheers, Neale.>
Re: Hi there from a fan, setting up my first saltwater reef
aquarium. 4/16/20
Hi Bob, once again. Thanks for all the great info. I’ll try my best to
get the 4’ tank then. Would having a 3’ tank somewhat reduce the
lifespan of my fish?
<Likely not much>
Also, I read that if I keep fish in trios (which I plan to do for my
Pajama Cardinals and my Chrysiptera Damsels), would it be very likely
for either or both species that one will be singled out and killed off?
<Might happen, better to have small odd numbers>
I’m also very curious as to what this fish could be. I’m pretty sure
it’s a Chrysiptera
<No; another genus>
damsel but I cannot identify the species. I’d be glad if you could
identify it for me and tell me what you know about it.
<A Pomacentrid of some sort. Perhaps review all genera, species listed
on WWM>
Regards,
Andrew

Re: Hi there from a fan, setting up my first saltwater reef

that to be true?
<Mmm; yes. >
Re: Hi there from a fan, setting up my first saltwater reef aquarium.

<Ok>
Re: Hi there from a fan, setting up my first saltwater reef aquarium.
4/17/20
Hi, Bob. Would an Australian Stripey in place of the angel or the
Cardinalfish or the damsels work in a 4 foot tank?
<Might>
Do you know anything about the longevity, hardiness, and feeding
requirements of these fish?
<Are usually quite hardy, eat most anything. To me, sort of like
Scats/scatophagids>
Also, if I really want to try keeping a pair of Marine Bettas in a 4 foot
tank, can that be done?
<... Please don't keep asking the same questions>
In that case I plan to get a smaller one and a larger one that’s about 50%
larger, I’ll observe them at the LFS for two weeks. I’ll also provide a cave
for each in my tank. Can it be safely done, having 2 Marine Bettas in my
tank?

Andrew
