Ammonia/ CP and Puffers 10/13/16
I have a situation that I'm hoping you can assist with. Tank is a 125
gal Fowlr with Dogface puffer, clown trigger, Harlequin Wrasse and Dragon Moray
<Trouble in future... first w/ the Clown Trigger... be on guard, alert for bite
30 gallon sump
Media reactor with GFO ( not running right now )
Ok so here's my situation. Trigger and wrasse can down with ich. Treated with
Ich Shield (CP%?)
Ich cleared up.
But my puffer came down with a spot on his side ( which we decided was probably
an injury from a hose syphon.
<Ah yes; VERY likely>
I was monitoring the water and doing 20 gallon water changes weekly. But just
yesterday I noticed the Moray breathing harder then normal and not in his usual
location. Water test reviled ammonia at .25
nitrite 0 and Nitrate 0
<How is NO3 rendered thus?>
Oh yeah so the puffers side wound that looked like a bacterial infection spread
to one of his eyes and until yesterday was hiding. The puffer ate last
night without any issues ( krill and squid).
<... see WWM re the nutrition of Tetraodontids. Want to avoid Vitamin B
I dosed heavy with Prime the first day I noticed the ammonia
<Won't solve the issue. You have too much life for this volume, your filtration;
use of treatments.... Need to "thin the herd" and/or add redundant
bio-filtration, circulation, aeration>
until I could do a water change that evening. All was good for a few days.
But today I have .25 again. Do you think the CP caused a die off in the live
rock hence elevating the ammonia?
<Quite likely; yes>
Or do you think what ever is effecting the puffer is causing it?
<Stress could be a factor here too>
I am going to do another water change tonight and add some beneficial bacteria.
Unfortunately I do not have a quarantine tank available to remove the puffer.
Any other thoughts?
<The above... Bob Fenner>
Thank you Brad
Re: Ammonia/ CP and Puffers 10/14/16
Thank you Bob
And yes I agree large bio load. I'm the first to admit that I have an impulse
buying issue. Originally the 6 ft tank was just going to be home for the moray.
<Too small even for just this>
But a 16" dragon looked lonely( I know he won't be arhat diazepam for long) and
the puffer was a rescue from another friends tank. Big regrets. I do enjoy the
trigger for now at 5" but am expecting a monster in the future. Have you seen
them cause major issues with morays?
<Oh yes; Some individuals are not overtly aggressive; some others will tolerate
NOTHING else living in their system>
I plan on thinning the herd to just those two individuals in the near future (
as soon as puffer is healthy and I can find a responsible owner to take them).
One more thing I had a hermit crab that disappeared shortly after the Ich Shield
dose. Maybe rotting away hidden causing ammonia spike.
And to clarify I'm using an API test kit with a reading of 0.25.
<I'd get, use a better test kit brand>
Thank you again for all of your help.
Dogface puffer with infection.... Mmmm
<Five megs of pix; can't upload from where I am. See our instructions re
I have been battling marine ich on a Clown trigger and Harlequin tusk
over the last week using Ich Shield (which seems to be working quite
But all of the sudden my DFP started to show signs of a wound on
<Is the exposure to the Ich Shield likely>
About the diameter of an standard airline tubing.( I know sounds like a
trigger bite) but I have never seen any aggression between the two.
<Still; could be>
So within the last couple of days it has changed dramatically to a much
larger circle surrounded by a dark ring. I'm quite certain this has
become a bacterial infection. What do you recommend for in tank
treatment? (No QT availability)
Here are the stats.
-Tank 6ft 125
And Nitrate undetectable.
18" Hawaiian Dragon
18" Whitemouth moray
6" Harlequin Tusk
5" Clown trigger.
9" Dog face Puffer
I know all of these guys will out grow my tank eventually. And I have
made arrangements with my close friend/supplier to re home all but the
Enchicore Pardalis to appropriate homes.
As all ways thank you for your service.
<Given what you list as livestock, the size of the system... the current
treatment regimen; I'd do nothing specifically to "treat" the puffer.
Just try to maintain good water quality and nutrition. Bob Fenner>
Re: Dogface puffer with infection
Thank you Bob
Sorry about the Picture size.
<Ahh; back home now. I swear this is an "intake wound" from getting
sucked up against a pump, powerhead... Do you have such in this
system... that is not screened? Bob Fenner>
Re: Dogface puffer with infection... A... hickey!
Yes actually he did come in contact with a siphon hose weeks ago.
I wasn't paying attention. Do you still think I should just let him recover
<Yes; this is what I'd do>
Also I have salinity a bit low 1.018 to aid with respiration while getting over
ich. Would this cause issues. Raising it very slow is what I've read before.
Dog face puffer question... Nutr. dis. 6/17/16
<Seven megs of uncropped pix; why?>
I have recently acquired a large dog-face puffer 9". He/ she seems very healthy
except for the eyes, they seem almost swollen/ sunken in but very clear.
<.... if you had read>
I have only had it in my tank (125 gallon) for a few days. It hasn't begun
eating yet but that is no surprise since he's still acclimating to his new home.
I have however tried fresh clams, raw shrimp and squid. I know how
important a fresh varied diet is for Puffers.
<Trouble.... vitamin B deficiency.... from this diet>
Attached are some pictures.
Also He did not inflate during transport or when being placed into the new tank
and actually seemed to adjust quit nicely.
Any advise or insight would be very helpful.
<Welcome. Bob Fenner>
Re: Dog face puffer question 6/17/16
Thank you Bob.
What would you recommend ? I can only assume this puffer was feed
primarily frozen krill for a good amount of his captive life.
<Trouble... possibly reversible>
I thought feeding fresh raw food such as Clams and Shrimp were the answer
until I read the article and the relationship between Thiaminase and B1.
Would this be advisable-
Vita Chem soaked food ( squid/shrimp Live snails ( marine) Cockles
<Sub much (at least half) of the shellfish with whole small fish (not
silversides), nutritious pellet staple. BobF>
Sick puffer 3/24/16
Hey again crew. My reticulated puffer is not doing well at all. He is in
a 120 Gallon FOWLR system(60x18x25) running a Wet dry filter and 20g
refugium. I perform weekly 50g Water changes, Nitrates stay around 20.
salinity -1.023. PH - 8.3. Temp - 77. ammonia/nitrite - 0
Bioload is 11" Reticulated Puffer, 4" Niger Trigger, Skunk Cleaner
Shrimp, hermit crabs and snails.
<Am surprised the Puffer and Trigger have not consumed the invert.s
Yesterday he quit eating completely after a week of showing signs of
appetite loss. He has cloudy eyes with specs that almost look like worms
<I see this... and evidence of... something... protozoan, worm... maybe
Trematodes at the base on on/in the pectoral fin?>
He is much more lethargic and he also is clamping one gill shut almost
all the time, although which gill is clamped has changed at least twice.
His other gill appears to be working extremely hard and the outside is
enlarged. When he was attempting to eat over the past few days he would
spasm like he was coughing or deflating. After several coughs, his gill
would start working and he would eat. Now it clamps back almost
immediately and he ignores food. He also is not coughing to open the
gill as often as he was a few days ago.
I believe he has some kind of fluke and I treated the tank with PraziPro
His condition does not appear to have changed, and I was wondering if i
should do a freshwater dip, or let the medicine have more time to work.
<I would do the dip if you feel comfortable with netting this fish>
I also read a post on here where PufferPunk did a hydrogen peroxide dip
to help a puffer with cloudy eyes.
<H2O2 is a very safe addition to dips/baths>
Am i totally off in my diagnosis or is there something more i can do?
Below are some pictures. Thanks in advance for any advice you can offer.
<The fish appears well-fleshed, so starvation isn't imminent... I would
allow the Prazi to work here, perhaps re-dose in two days. IF you had
another system; I'd move this puffer, treat it w/ Metronidazole AND the
anthelminthic. Bob Fenner>
Re: Sick puffer 3/25/16
Thanks for the quick response!
My plan for netting him was to use a extra large zip lock baggy and guide
him in with my hand. He allows me to handle him and actually comes to my
hand for the attention if it is in or near the tank.
I would then move him to a 30g brute trashcan that I have setup for the dip.
I don't want to take a chance of him puffing up and getting air, so some of
the salt water would be added to the container when I put him in. I plan on
having roughly 20g of freshwater and am hoping this will be enough to dilute
what salt water is added. .
I have a neglected 29g tank that is fully cycled with some crabs, snails and
soft corals. I also have a 180g tank with crabs and snails and soft coral
that recently had a sick clown trigger (We discussed him previously.
He did not end up making it). I can put the livestock from the 29g in the
180 and use the 29g as a hospital tank after I replace the water. It will
not give him much room, he is a very large fish. I found two types of
<Two? There is only one compound>
and am leaning toward General Cure by API unless you think I should use
something different. Would dosing the 120g that he is currently in with
General Cure instead of moving him be a bad idea?
<Possibly... there may be too much die-off; causing troubles>
It did not appear to be dangerous to the livestock or biological filtration
at the correct dosage from what I have read. It is a bit pricey though.
Should the Niger be treated with Metronidazole as well?
<Mmmm; wish there was sampling, microscopic examination.... both could,
should be treated>
<Too much to simply state in going back/forth on the Net. B>
Re: Sick puffer 3/25/16
Quick update on the puffer. he appeared to be excreting white stringy
looking stuff tonight.
<Do you have a microscope? A loupe, magnifying glass to examine this
It appeared to be hard for him to pass though. Upon closer inspection I saw
a clear tube like object sticking out of his anus as well.
<Colon, prolapsing. Use these two words in WWM search tools>
It was sticking out about 4 mm and appeared hollow. After he was done trying
to pass the mass of white stuff and his anus closed, the tube also
Re: Sick puffer
The tube does not really look like the pictures of prolapsed colons. The tube is
just under 1 mm in diameter. I'm not sure exactly how long it is, but it has
extended about 4 mm from the anus. Can such a thin clear tube be a prolapsed
<Mmm; not this small; no. Perhaps a worm... Nematode? B>
I will try and get a picture tonight. I do not currently have access to a
microscope, but I will order a loupe magnifying glass directly.
Dog Faced Puffer fish with cysts on skin.... rdg
<Anne; and I have been to York>
I am hoping someone here can help my puffer. He has what can be described as
boils/cysts on his skin. There is a very small, thin, white, stringy
substance leaking out of the cysts.
He also now seems as if he wants to eat but can't,

food goes in but straight back out again. His mouth seems sore to open.

of the cooper treatment.
He is in a 90L QT and water parameters are:
Any help with this would be much appreciated as I'm afraid I'm going to lose him
as I just can't find any info on such a thing. My local vet doesn't have any
Thank you in anticipation.

Puffer with strange growths 10/15/15
Hi again crew,
First, thanks for the help with my clown trigger. He is doing great.
Currently my reticulated puffer has some odd growths on his fins and skin.
<See these in your pix>
They started on fins, then appeared on the skin where the fin rub. I need some
help identifying what it is, and any info in how to treat would be much
<Mmm; wish i was back at State, taking histology from Rick Phleger.... to
sample, embed, section.... and look at this stuff under a 'scope>
It is definitely getting worse and has been for several months. They are
spreading from both side fins to his body. I finally was able to get some decent
pics. They and tank info is below.
<Well; some of it "looks" like Lymphocystis (viral; see WWM re), the bulbous
bump... maybe an -oma of some sort, possibly (though doubtful) parasitic...
Might just be derived from the Trigger biting the Puffer>
He is in a 120 Gallon FOWLR system(60x18x25) running a Wet dry filter and 20g
refugium. I perform weekly 50g Water changes, Nitrates stay around 20.
salinity -1.023. PH - 8.4. Temp - 76. ammonia/nitrite - 0
<All this is fine>
Bioload is 11" Reticulated Puffer, 4" Niger Trigger, 1" Reef Chromis, Skunk
Cleaner Shrimp, hermit crabs and snails.

SW Tetraodont, dis... diag. 9/17/15
You have been recommend to me by a person on Devon marina. I have a problem with
my puffer fish and was wondering if you could help. The problem is with some
sort of fungus growth on his fins, at first his fins formed very small white
spots on them but over the last 18 months they have become worse and we can't
seem to get rid of them, it also appears to have spread to his skin around his
fins which are dark coloured and looks like warts! The tank is cleaned daily,
he has regular water changes, all the parameters are tested frequent and are in
good water order and the ro machine which takes all the bad out of the water is
working perfectly! Any advice would be appreciated. I have attached some
pictures of him
<There appears to be some sort of tumorous growth and from the appearance and
description fluke (Trematode) involvement. The first might be excised, or a
purposeful cleaner organism tried that might not be eaten. Flukes are gone over
on WWM (search, read on the site). Am concerned w/ the rotund appearance of this
fish. And concerned re Thiaminase poisoning. What is it fed? See WWM re this as
well. Do you need help using the search tool, indices?

Stressed Dog face puffer 2/26/14
Hello! My name is Kris. I have a 100 gallon tank that includes
dogface puffer 3.5", niger trigger 2", sail fin tang 3" and
recently added a 2" Picasso trigger.
<These Balistids... are likely directly and not harassing the Arothron>
Okay so since the addition of the Picasso , the puffer has been very
dark in color ( almost black) and hangs out in his cave most of the day
( which isn't terribly unusual) He's eating 100% like he always has and
i use garlic on the food as an immune system booster/ prophylactic.
<Not much; better on pastas>
Here's what the scene looks like... the puffer hangs out in his little
cave that he likes and for whatever reason, the Picasso ( Pablo) keeps
coming over to where the puffer is and rubbing his body gently and
slowly against the puffer. There has been no biting, fighting or
otherwise outward altercations.
What does that behavior mean?
<It doesn't like the Rhinecanthus... nor the Odonus>
Will it pass?
<The fish will... that is; die, if not relocated, or the triggers moved
Is it enough to stress the puffer out to death if it doesn't stop? Or
will the puffer just get used to the presence/behavior of Pablo and "get
All other tank mates are just fine and Pablo does this to the sail fin
tang as well and she doesn't seem to mind at all..... what's the deal?
P.S. I have a 180 gallon on order that should be here by Saturday.. (
today is Tuesday)
Thank you in advance for your speedy and thorough response. I
don't have a problem selling Pablo back to the store if he isn't a good
tank mate, but I don't want to be hasty in case the puffer is just being
a "diva" as i have read that they can be particularly "emotional".

Sick Dog face Puffer; new, uncycled sys., NH4OH, Clown
HI everyone!! First let me say that it is AWESOME to have a
knowledgeable resource for answers to my fish questions other than
relying on the LFS for extremely biased advise. <advice> I have read
some of your forums/threads on sick
puffers and have been putting together parts from each story but I
decided to just give you my story and we can go from there.
Here's a snapshot of my tank thus far:
setup started on 1-15-14
<Less than a month ago. Is this system fully cycled?>
60 lbs live sand
70 lbs live rock ( cured or so i was told)
Octopus skimmer BH 1000 ( rated for 125 gallons)
Penguin Bio wheel 350 ( not running the bio wheels, it's just to agitate
the surface and to house any filter media I may want to add in the
future..carbon etc.) Currently nothing is in it but it's on.
3 powerheads ( not sure exact gph right this second)
Water parameters: ( tested today with API liquid test kit)
NH3: almost up to 0.25 ( i know, I know..)
Nitrates: 10 ppm
Tank inhabitants: Dog face puffer 3.5", Clown trigger juvenile 1.5",
Coral Beauty 1.5".
<... the Trigger... will get too large, mean...>
All that said, i think that the ammonia went up because i added the dog
face at the same time that I added 15 lbs of "live cured rock".
I put that in quotes because I think that it had enough die off to alter
So my puffer ( added a week ago) was very active as were
the others . Eating well, being active , no fights, no aggression.
Today my puffer isn't eating and he has changed color to that same dark
gray almost black like he does
when he goes to sleep. He's been hiding all day and hasn't come
out at all. I did a water change ( 15 gallons) and am using RODI
water. I also noticed that today the clown trigger had white speckles on
it's fins but was behaving normally. Coral beauty however is in
bad shape. She has a cloudy eye and rough around the edges looking
dorsal fin. Eating and behaving normally though.
I freaked out and used a little prime to reduce the ammonia to the less
toxic version. I know that the test will still show it so i think
that that's where Im reading 0.25 in ammonia. I have no hospital
tank and since at least one thing was wrong with all of them, I freaked
out and wanted to treat the tank. here's what I've done so far besides
Turned off skimmer
added Dr. Tim's First defense to reduce stress on fishes
added Dr. Tim's nitrifying bacteria because I figured that the live
rock, live sand, and quick start bacteria that I initially used to start
the tank, hadn't quite built up enough of a bio filter to handle the
load that I put on the tank. I read up on his stuff and it is said to
work fast and obviously couldn't hurt the situation. Let me say
too, that before i got my own test kit, that I was getting my water
tested at the LFS every other day and saw my tank go through the
nitrogen cycle BEFORE adding ANY of these fishes. Lastly I was
freaking out about the ICH potential and the cloudy eye of the Coral
Beauty, but didn't want to copper my tank so I bought some stuff called
Microbe-Lift by Herbtana that is supposed to be added to the DT to
combat a host of diseases including Ich. LFS and the bottle say
that it's natural and that it won't affect what little bacteria that I
I know what I did wrong... ( hindsight is 20/20) I increased my load too
fast too soon. But now that Im in this mess, I need to know how to
get out of it and is it too late to save my fishes?
Oh btw, I've increased the temp of my tank to 82 degrees F and am
keeping the lights off too. Is there hope or are my dog face and
the others doomed
to die for my stupidity and hastiness?
<... Don't panic! And stop feeding period... allow this
system to cycle out all ammonia. Don't change anything till.
Serious problem with Dogface Puffer... fdg., hlth. 1/14/14
I think I have a serious problem going on with my dogface puffer and
have absolutely no idea what it could be. I got him about 5 weeks ago
and ever since I got him something hasn't been right. I haven't seen him
eat anything at all and I know that he has to of eaten something bc he
would be dead by now.
<Not necessarily... have you searched, read on WWM re?>
I took him out of my display tank 2 days ago because something isn't right
and hasn't been.
<What other fishes are here? Possibly this fish is being
He has been very lethargic, just sits on the bottom or hides in the live
rock. When he swims around he runs into the glass and looks like he's
trying to eat it. His eyes are completely clouded over with a few little
white dots on them, both eyes are this way. His fins also have white
dots all over them. Sometimes his fins are at his side when he's just
laying on the bottom. These whitish dots make me think that it's either
Ich or velvet but I'm not sure. Some times he is breathing very rapidly
and others seem like he's breathing normal. I've tried feeding just
about every food possible that I can think of but he doesn't eat it. If
I stick a silverside right by it's mouth it bites at it and takes in a
lil bit then spits it right back out and moves away. I have no idea what
to do, what the problem is, and how I should go about treating it. Any
help would be greatly appreciated because I don't want to lose him!

Re: Serious problem with Dogface Puffer
I've been reading and reading on WWM trying to figure out what
the problem most likely is
<Seen your pix... at least some sort of Protozoan; most likely Crypt>
but I haven't been able to figure it out. After reading on WWM it seems
like it is Ich or velvet but it's very hard to tell since it doesn't
seem like any of the other fish are acting strange or different. He is
in the tank with a small batfish & a blue velvet damsel and it doesn't
seem like either of them bother or pick on him at all.
<Well, these other species are more "Ich tolerant"... Likely the
system (most are) is infested>
The batfish swims & stays in one area of the tank. I waited so long
because I'm new to this and was thinking that he was acclimating in the
first week or two and it may have cleared up and also was thinking it
was possibly a bacterial infection so I was treating him with an
antibiotic to see if he would improve.
<... you need to act fast, decisively... Either some hypo route followed
by worthwhile treatment (perhaps a quinine cpd.)... I'd be READING, and
ACTING ASAP. BobF>
Re: Serious problem with Dogface Puffer 1/15/14
Here are some pictures I took last night of him in the QT tank after
putting some food for him to try and eat.
|Re: Serious problem with Dogface Puffer
I will get right on it and do hypo. Should I place all the fish in QT and
leave the display tank empty to rid the tank of crypto? Thank you so much
for your help and hope I am able to save him!

Unknown disease in puffer.... please help
Hello Wet Web Crew,
I am hoping you can shed some light on a very disturbing disease that we
have been experiencing with some of our fish. This puffer is in an
aquarium that has been stable for a few years, with no new fish coming
or going. I have seen these lesions appear on some of our newly
introduced fish in our quarantine systems, and despite freshwater dips
with Methylene blue and an increased copper level in the system
these fish always perish a very gruesome death within 24-48 hours of
these lesions first appearing. It will attack puffers and angelfish
specifically, and doesn’t seem to bother other fish. Please
give me any insight as to what we are dealing with here and how to
handle / stop its transmission. I have a microscope available, and if I
manage to get to this fish I will try to get some skin scrapes.
Any affected fish stop feeding, appear lethargic, have these lesions of
discolored skin, which in the angels progress to bloody open wounds, the
puffers just have expanding patches of discoloration and rapid decline
until dead in 24-48 hours.
Any help appreciated,
<I have witnessed such rapid onset losses w/ this appearance; and have
attributed (guessed) them to emphysematosis ("gas bubble disease")...
Somewhere in your circulation system/s there is a site of air
entrainment... the fine bubbles going into solution, getting into the
fish/es and surfacing as these "lesions"... There are a few techniques
for detecting these sites. Otherwise, perhaps a histological work-up of
the areas mal-affected, thin sectioning, H & E staining will reveal

Puffer Accidentally Bitten 1/3/14
Hi Bob. I have an 8 inch dogface puffer and an 8 inch Harlequin
Tusk in my 300 gallon FOWLR (along with other fish).
Today, during feeding, the 2 went for the same piece of food and the
Tusk bit the puffer on the side of the face. The puffer is acting
normally and continued eating, but there is a pretty large cut on it's
face. Should I leave the puffer alone or remove him to QT?
<I would leave it where it is. These animals ARE tough; will almost
assuredly (self) repair>
I'm afraid of a bacterial infection. Anything in particular I can
<Just the usual good maintenance and nutrition. Do you use (soak foods)
HUFAs, vitamins, iodide-ate? I might double dose all for a week>
Thanks in advance,

Are you joking? 26 megs? Resend in Kbytes.
Puppy the sick Dogface Puffer.... 12/3/13
Good morning.. I have a small dogface puffer now for about 4 months or
so. Purchased from a local LFS store. Starting out he was doing ok in
our 90 gallon (we are planning on a larger tank soon) with live rock
<That its damaged its one eye on apparently>
and lots of inverts (his choice snack). He has gone through a
couple Cupramine treatments
<Tetraodonts don't "like" copper exposure>
at the fish store and one after we purchased him. We are unsure of what he
may have at this moment in time. For about a week or so, he seemed fine,
swimming around and showing his true personality. I did notice that his
BMs changed a lil. He will have a large BM but it seems like a whitish
streamy thing comes out with him. Also, now he is very lethargic and
doesn’t want to come out much. He has been eating a diet of
clams from a local organic store, krill, LRS Fish Frenzy (frozen fish
mixture with some shrimp, clams, etc).
<... see (search, read) WWM re these fishes diets... this one is
His appetite is still really good. He has this white film over his eye now
which started as white dots. It seems to be getting worse now.
My LFS suggested trying Seachem's Metronidazole
<..... no. Of no use here and toxic>
mixed in with his food. He doesn’t really like the taste. He does get a
few bites in at least. My concern is if what I am doing is good enough
or should I quarantine him and treat with the Metronidazole or maybe
<Read on WWM re unilateral eye issues... damage from trauma... No
I also noticed that yesterday, he seemed to be "coughing" a few times. I
do see a few lil tears in his fins too. Could this be evil Ich again?
<... not likely>
Attached are a couple of pics of the best shots I could get. Any
suggestions would be great!

Puffer with White Pimple looking thing on Eyelid
Good afternoon! Ok, so it appears that our Dogface puffer has developed
a white pimple spot on eyelid. I see no other marks or bumps on him or
any other fish.
<Mmm, just the one fish and one zot...>
Currently he is in a 90gall tank with a snowflake eel and a coral
beauty. We had an outbreak of Ich a few months ago and fallowed the tank
for about 45days. We just introduced the fish back in the 90gallon tank
and everything seemed fine. But now, puppy the puffer fish has developed
this white spot on his eyelid. Is there any way to determine what
<Well; yes... but not worth doing in my opinion... take the fish out,
sample some body slime, perhaps the dot itself, look under a 'scope...
study up re what you're seeing...>
He is eating normally and acting fine.

conditions and good nutrition>
Thanks so much!

Puffer parasite?? 12/7/12
We have a new golden puffer for about 4 months now with no issues..
All of the sudden tonight when we went to feed them he had these rice like
"parasites" all over his body and one of his eyes.
None of the other fish in the tank have any signs of this and he is acting
normal so far.
<Have tried enlarging some of these "zots" and enhancing the image... They
look like congealed spots of body mucus more than anything discrete; not
like a live organism. Tetraodonts are quite slimy and often particulates
will adhere to them... I'd review what your water quality, any supplements,
treatments you've added to the water... and not treat this fish/system in
any way. Bob Fenner>
Dogface puffer missing his tail 11/4/12
I have been searching your site of late but have not been able to
identify exactly what is going on with my Dogface Puffer. The puffer is
about 3.5 inches long and resides in a 180 gallon FOWLR aquarium. His
tankmates are a Maculosus Angel, an Annularis Angel, a Lunare
Maroon Clown, a Flame Hawkfish, and a Coral Beauty. He is fat, active at
feeding time and at night, eats just about everything I put in the tank,
and seems to be pretty healthy with the exception of his tail.
My puffer looks like someone chewed off his tailfin.
<Might have... it wouldn't have disappeared on its own... The prime
suspects are the large angels and Premnas>
From what I can tell he does not have fin rot, as his entire tailfin is
gone. There appears to be rather extensive tissue damage (ragged, torn
tissue), although I have never seen another fish biting or harassing
<Going on when you're not looking>
Does this sound like a bacterial infection/Finrot, or is it more likely
the result of aggressive behavior from a tankmate?
<Almost assuredly the latter>
Should I be worried about a secondary infection from the tissue damage?
<Not if the animal is eating/healthy and there's no evidence otherwise;
but it should be moved elsewhere, lest it be the recipient of further
The puffer's behavior seems very normal, but his tail really looks
horrible. Is there anything I should be doing other than regular water
changes and providing a proper diet?
<Move it; or the perpetrator/s>
Thanks for your help,
<Welcome. Bob Fenner>
Hi crew! I've been having a problem the last few weeks with my dogface
puffer and some of my other inhabitants. We'll start with the tank. It
is a 220 gallon FOWLR with a 40 gallon sump/refugium with miracle mud.
It has been set up for three years. Temp is 79, ammonia 0, nitrite 0,
nitrate 20, ph 8.4. Inhabitants are a dogface puffer, passer
angel, and an Australian harlequin tusk. About a
week or two ago, my puffer started lying around more and stopped eating.
<True puffers (Tetraodontids) "do this" (lethargy, feeding strikes) at
times; sans known cause>
I checked water quality and nothing seemed out of order. So I just kept
offering food with no luck.
<Mmm, what foods specifically? Some fed too much, too often, exclusively
are trouble. Read here re:
The only thing that seems out of order with his appearance is that his
fins are a little tattered even though he is not getting "picked on" by
any of the others.
<Mmm... then wherefore the tattered fins? I'd be watching the Passer...>
Around that same time, my angel started to do the same thing. Only it
looks like he is getting hole in the head like I have seen on Oscars.
<See WWM re... vitamins, HUFAs, perhaps a cut-back on GAC use:
and the linked files above>
My last angel came down with HLLE and this looks nothing like it. The
tusk is doing great. He eats like a pig and is always gliding around the

Re: Sick Puffer 10/25/12
Hi Bob. I forgot to add that I do not use carbon in my systems. In my
experience that seems to cause more harm than good. I use no chemical
filtration. I just use 100 micron filter socks and a sponge filters that
get changed weekly. That in conjunction with my refugium and biological
filter seems to work well for me.
<Ah good. B>

I doubt the passer is the cause of the puffer's fin damage. He hasn't
moved out from the live rock in about 5-6 days now. Should I try
to treat them with Melafix or anything?

Help with my puffer 10/25/12
I have a mappa puffer. I came home and found him
hanging upside down by my overflow. It seems he inflated or
gulped some air somehow. He is having buoyancy problems.
What can I do to help?
<Mmm, at the low end, nothing, to the higher, secure all such intakes
and even massage the belly area toward the mouth (underwater) in an
attempt to expel the air>
I tried to "burp" him but it didn't work.

and sink him to the bottom of my tank with a rock on top.

Re: Help with my puffer 10/25/12
Thanks for your reply. I just came home from work and everything was
<Ah, good news>
It was like nothing happened. According to my LFS, putting him in a
container at the bottom of the tank helps to work the air out due to
increased pressure. Also, I put Mysis in there for him to eat that also
helps to move stuff around inside him. Im not saying I know why it
worked but it did and just wanted to let you know for future reference.
As always, thanks for helping me.

Strange air bubble in puffer
Bob, I need your expertise. This morning I woke up and noticed my
puffer has a HUGE air bubble on it's side. See the attached

No new fish have been added. Water quality in check. The only
thing different is that I fed a crayfish last night. Could this
possibly be the cause?

Dog Face Puffer in Potential Trouble
I have been using your site since first purchasing my tank, its a great

The puffer has been acting a little strange since purchased. He
began eating immediately, but only live ghost shrimp, muscles and clams
in the half shell.
<Spoiled... and likely Thiaminase poisoned. Read here:
and on WWM re Tetraodont foods/feeding/nutrition. You need to widen the
diet... Spectrum pellets are a fave>
He is very shy, usually hides, and only comes out for food. My water
parameters last week were Ammonia = 0, Nitrites= 0 Nitrates = 40ppm
<Too high by twice... due to crowding, foods/feeding and likely
types of filtration employed and not. See WWM re NO3 control... Keep
under 20 ppm.

salinity = 1.024, and Ph= 8.2. Due to the nitrates i did a 15
gallon water change, which lowered the nitrates to 10 ppm.
Unfortunately, when i awoke, sweet potato ( dogface puffer ) looked
unhealthy, and was acting stranger then normal. I see no physical signs
of Ich, or problems, but he has occasionally been slamming his side
into the tank wall. He stopped eating, looks to have thinned out,
darkened in color, and now is literally hiding in a cave breathing
heavily. I went to the LFS with a description and photos, and was told
maybe he was stressed ( it seems to be something more).

Anyway Puffer instead of being very light grey has darker
speckled grey spots. Skin looks a bit like when he has blown up

He is also staying in front of powerhead flow.

up against the intake...>
Then he might hide away in a cave.
Just doesn't look or act the same.
He has flashed against rocks a few times. Not a lot though and no
sign of itch.
He is eating as much as ever and looking for food every time i
approach the tank.

Water levels are normal but nitrate/nitrite/ammonia could be present,
since I haven't done a water change in 3 weeks. So my pufferfish
rectum is actually out and exposed, and you can see the waste in his
rectum. It is like a lump where his anus is. This has been going on for
2 days now. His stomach doesn't seem bloated and I didn't feed

Re: Reticulated pufferfish is constipated? 10/4/11
Hey, thanks for the info, the pufferfish just pooped out the waste that
was stuck in his rectum. The waste was a solid piece (not usual) and it
was kinda hard. Does this mean that his illness is starting to
alleviate? Also about his diet, what should I feed him? My pufferfish
would only eat shrimp or mussels. I've tried squid, fish, and other
stuff but he refuse to eat anything besides live crab/crawfishes or
frozen mussels and shrimp.

Help. Dogface puffer swimming
Hello, I've read through a lot of questions trying to find a
issue, but can't seem to find one. I have a 60g
FOWLR with a 4" dogface puffer,
<This is way too small a volume for this fish>
3 damsels, and a clam. I've had the puffer for about 3
<"Dwarfed", "Bonsai'd"... made and kept
small here from metabolic feedback (living in its own wastes so to
speak). Read here: http://wetwebmedia.com/FWSubWebIndex/GrwLmtChems.htm
Just recently (about 2 weeks) he has been acting differently. On a side
note, me and my wife just had a baby (2 months old), so for a bit some
of the care I put on the tank was slipping. I checked my levels a week
ago and found my pH was low, about 7.6-7.8.
<Whoa! This scale is base 10 (log)...>
I did a 20% change and added the pH buffer
<Needs to be done very gradually... from pre-mixed new saltwater
additions, NOT added directly to the tank>
for 2 days after that and the levels went back to 8.2 - 8.3 within 2-3
days. Ammonia was 0, Nitrite was 0, and Nitrate was about 20. So back
to my puffer, he seems to be swimming a little lopsided and recently
was even upside down.
He can't swim and stay up anymore either, he is always cruising the
bottom of the tank and when he does force himself to swim up, he
immediately drops down to the bottom. He used to always hover around
the middle or close to the top swimming back and forth, now he just
swims circle around the bottom. He still eats, but only if I physically
put the food in front of his face with tongs. Before he used to come
get anything I put in the tank. I feel him a variety of squid,
silversides, krill, and clam.
<Not a good diet... read here: http://wetwebmedia.com/ca/volume_6/volume_6_1/thiaminase.htm
and here: http://wetwebmedia.com/trupuffdgfaqs.htm
I mix it up. I went to the LF store and asked what to do. The owner
said I should QT the puffer for 3-4 days and gave me EM Erythromycin
and Triple Sulfa,
<? Of no use here whatsoever>
which I medicated him with for 4 days. I just put him back in the
regular tank and he is swimming around a lot more, but still looks the
same, not able to go to the top. Anything you can tell me would help.

re: Help. Dogface puffer swimming issue
Thanks for the reply. After reading your reply, I guess I haven't
been treating my puffer well and I didn't even know it. I am going
to do my best to make things right for my puffer.
I have a 150g tank in my garage I have been building a stand for. I am
almost finished and will set that up ASAP to give him a bigger home. As
far as filtration, I have a Fluval FX5 I will use along with a Fluval
I read I should be shooting for about 10 time water volume per hour
with a puffer, so I'll do the math and add another canister if
needed. I also have and will be using a skimmer.
As far as the pH, I did add the buffer to new water I had made, not
directly in the tank and am maintaining the levels were they are now.
Ph 8.2-8.3, Ammonia 0, Nitrite 0, Nitrate 20.
After reading your response about his diet, I was shocked. I had never
heard of Thiaminase and everything I always bought for him to eat was
frozen and what I listed before, which apparently was all Thiaminase
based food. My LF store had always told me it was a good diet for

diet to Tilapia (fresh from the food store, I'll freeze it as
needed and soak it in vitamins, mussels (maybe a few times a week), and
cockles. Once a week I will give him a silverside or some clam since he
does like them, but again I'll soak them in vitamins.
Do you think this might get him better,
any other suggestions as far as anything else I might be able to

<Mmm, really, this puffer (should by now, through growth) needs a
much larger volume>
Have not introduced ANYTHING new to tank, not even live rock or gravel
Recently noticed Puffer rubbing on the live rock. Thought nothing of it
because he's a bit of a "spaz", but now see a skin
eruption on his jaw line about 3/4 of an inch from his mouth. The spit
is a perfect dark ring with a dark center spot with five white speckles
inside of that (definitely not Ich). I thought, at first it was an open
wound, but under closer inspection see that it is completely smooth
like the rest of his skin.
Eyes clear; appetite great, activity level is as usual.
What is this and what medicine can I apply to the water?
<... likely environmental stress as a term... Again, this fish has
been 'bonsai'ed' by life conditions>

My panda puffer has swallowed a rounded piece of dead
I am concerned for my panda puffer; it has swallowed a rounded piece of
dead coral that fortunately was polished. I hope that it will not make
him internal injuries. How can I help my fish?
<Really only being patient, time going by>
Do you think that it will expel naturally. The piece was large enough
to pass by his mouth! Yesterday, the fish has eaten normally but today
it is a little lethargic. Today it has done a little poo.
Thank you for your support
<This too should pass in time... I've seen puffer species eat a
bunch of hard, unusual materials in the wild... Bob
Puffer with "skin growths" --
Hey WWM crew,
I have a question that pertains to my yellow-belly dogface
puffer. He has numerous small circular growths all over his body,
they look almost like "freckles."
<I see these>
I have searched extensively and asked several forums without any
pointers in the right direction. These growths don't appear
to bother him at all. I have enclosed some pictures to see if you
guys can identify what it is. Thank you!!!
<Some sort of skin irritation (not Neuromast/HLLE trouble)...
likely something to do w/ water chemistry... which you proffer no
data re. Could well be summat that there is no simple measure of.
Do put the string
"puffer skin trouble" in the search tool here:
and read some of the cached views for the saltwater queries. Bob
Dogface Puffer won't eat
I recently purchased (almost 24 hours ago) a Dogface puffer.
He/she's about 3" long including the tail and is in with a
harlequin Tuskfish (4.5"), niger trigger(4"),
<May not "get along" with this fish>
Goldbar wrasse(5") and a yellow tang who is 6"
in a 150 gallon tank(US) with protein skimming. The yellow tang
threatens the puffer when he/she(the puffer) goes near the tang's
territory with his acanthus. Also the puffer won't eat anything. I
know he/she probably won't eat anything in the next 24 hours when
you acclimate them but also seems to have slightly overgrown teeth. The
reason I assume this is because he/she goes to the side of the tank and
seems to be "biting" the glass or his/her reflection.
<Likely interacting w/ its reflection... but perhaps trying to
The others don't bother him/her. Also when the yellow tang
threatens him/her, his/her tail goes to the side of the body, like a
submissive gesture I suppose.
Thanks a bunch!

Dogface puffer, hlth., sys., nutr. --
I recently moved from a 25 gallon to a 115 gallon tank.
and bought a dogface 2 weeks ago.
<Will do much better in a bigger tank than 115 Imperial gallons.
Realistically, 200 gallons is nearer the mark. These fish do grow very
big, very fast. They're also very active.>
Everything been fine until today. He looks really ill, not eating and
keeps screwing his face up....and moping about behind the live
<Indeed. While Arothron species are extremely hardy in many ways,
they're easily stressed by the poor conditions they themselves
create thanks to their large size and massive appetite. Review aquarium
size relative to the Arothron specimen you have, with a fish bigger
than, say, 15 cm/6 inches needing a much bigger tank than you have. Do

<Stop feeding! Check filtration is matured and working. Maintain
filters as required, adding secondary filters if necessary. Let's
say you're aiming for a turnover of 10 times the volume of the tank
per hour, the minimum for this sort of puffer, you'd need a pump
rated at 10 x 115 = 1,150 gallons/hour. A protein skimmer is essential
because of all the nitrogenous material dumped into the tank whenever
you feed your pufferfish.>
Realised my external filter which I moved over from last tank (while my
trickle filter matures) had been unplugged.
Did water change and have filter running again now.
All other fish well.
Thought it may be food as he eats prawns and dillies that others
<Hmm'¦ earthworms and prawns are reasonable foods, though
Bob F. would probably warn you away from terrestrial protein sources on
principle. As for prawns, while fine as a treat, they are rich in
Thiaminase, and shouldn't be used more than once or twice per week.
Gut-loaded live river shrimp are better. Otherwise, concentrate on
Thiaminase-free foods: cockles, tilapia fillet, certain types of
Maybe a prawn was off ?
<Possibly, but usually fish reject rotten seafood.>
Any ideas of what it could be or any treatment I could use ?
<More likely environmental. Review the tank, tankmates, filtration.
Check water chemistry, salinity is adequate. Oxygen is a key limiting
factor, and external canister filters remove oxygen, so without
sufficient circulation in the tank, you can easily end up with low
oxygen conditions likely to stress your puffer. Their small gill
openings mean they find it hard to breathe "deeply", yet
their oxygen demands are very high because they're so
Also is it true that if he died he can pollute the whole tank fatally
<Potentially, but any dead fish can do that. If you're asking if
the poisons in a puffer's tissues leak out after death and kill the
livestock, no, that doesn't normally happen. Boxfish can secrete
toxins through their skins, but puffers don't.>

Thanks for the rapid response.

don't be overly trusting in what you've got going on here. Keep
a close eye on oxygen concentration and nitrate level.>
He now seems to have gone a really dark colour and looking pretty grim
<Arothron hispidus will change colour dramatically when stressed. I
bought my first specimen as a FRESHWATER fish, and while they were a
very subdued colour under such conditions, once moved to a brackish
water aquarium they perked right up. These are very hardy animals. What
are its tankmates? How are they behaving? On paper at least, Arothron
spp. are among the tougher marine fish, and some of the few species to
be kept successfully for 5+ years in captivity back in the 70s and
early 80s when marine fishkeeping was still in its infancy. If the
other fish look happy, then yes, consider diet and/or poisoning as
possible issue -- note than puffers tend to be acutely sensitive to
copper, perhaps more so than most other commonly kept fish. On the
other hand, if everyone is off their food, then something else
is likely going on.>
Has been fed almost exclusively on prawns....About 2 a day....not
<Indeed not. Tilapia fillet and cockles are the two ideal staples
for bigger specimens. Very young ones enjoy bloodworms, but the degree
to which these are healthy for marine fish is debatable, though
it's worth stating that juvenile Arothron hispidus live in
estuaries and rivers, so insects probably are part of their natural
diet. They're also herbivorous, so some green foods, e.g., cooked
peas, should be provided.>
Thanks anyway and I'll see how he goes but gone bad very quickly so
not overly optimistic.
<Good luck. Cheers, Neale.>
Re: Dogface puffer -- 12/20/10
Yes all tankmates healthy and eating
<That's helpful to know.>
Scared to tell you what they are , as due to some bad advice I am
overstocked. All very small now (1-2 inches) but will be doing some
rehoming in the future.
<Ah, yes, it would indeed seem so.>
<To about 20 cm; not a bad aquarium fish for rough-and-tumble
systems alongside large puffers.>
<Not a great companion for the wrasse, but might work with the
puffer, given space. Do bear in mind these angels are strongly
herbivorous, and their diet needs contain lots of fresh greens as well
as sponges, rather than generic fish foods.>

Actually left a small part of his prawn yesterday which I had to fish
out. Maybe bit dodgy.
Surprised at the speed of illness though....Keep thinking he s dead
then his eyes move....Nothing else at all and he s not changed position
for a couple of hours.
<If he's eaten something bad, there's not much you can do
beyond ensuring optimal environmental conditions. I'd expect him to
recover, all things being equal, though it may take a day or two before
be perks up again.>
Re: Dogface puffer - 12/20/10
Cheers Neale thanks a lot.
He has actually moved now so fingers crossed.
Yes jam sandwich goby. Only got him today as I cant have a clean up
crew due to wrasse and puffer so thought this might help a bit.
<Redundant. Clean-up crews are specifically for use in reef tanks,
where it's difficult or impossible to move rocks and siphon out
detritus. In EVERY other type of aquarium, it's ALWAYS better to
physically remove waste because that'll reduce the amount of
nitrogenous material in the water.>
Do feed frozen tablet greens and also Nori on a clip.
Struggling a bit for Angel food but got some ocean nutrition formula 2
pellets which seem to be good.
<Yes; do look at specific Angelfish frozen food mixes. Sponges are
an important component.>
All fish are eating variety of foods and well. Mysis brine shrimp krill
Nori formula 1 and 2 plus live brine and a marine mix tablet. Will eat
flake too but don't tend to use it.

Thanks again Neale
Puffer as normal this morning , Made up really thought he was a goner
till I spoke to you.
Just fed him 2 dillies (all I have at the minute ), Snowed in now but
think LFS does a frozen cockles.
<Good. So do many supermarkets; Waitrose for example has them
regularly, and buying a batch from there will usually be cheaper than
buying them at the pet shop. Ask for some that are still frozen, pop
them into an airtight container in the freezer, and defrost as
required! You could actually get everything you need from Waitrose:
cockles, tilapia fillet, mussels, squid, prawns. Be sure the
Thiaminase-containing foods are used sparingly, and that's a
balanced diet right there!>
Prawns will become just an occasional treat. Tend to struggle a bit
with selective food. Have seen an ocean nutrition one containing
sponges on the net but cant get any in England.
<Ah, while sponges are nice to have in the diet of Pomacanthus
species, it's the green component that's essential. Look at the
marine fish foods like "Vegetarian Diet" from TMC that
include cooked spinach and algae alongside various small invertebrates.
Sushi Nori sheets can be picked up in British grocery stores very
inexpensively, and if you happen to have an Asian supermarket nearby,
10 sheets will only set you back about Â£1-1.50 (supermarket
prices tend to be slightly higher, Â£1 for 5 sheets being
typical). Anyway, this stuff is readily accepted by Tangs and
Angelfish. Asian supermarkets will also have other types of algae on
sale, and these can be experimented with as you wish. Organically-grown
lettuce and spinach may be useful foods, though their nutrient content
are probably not very high. Bob is somewhat hostile to the use of
terrestrial plants in the diet of marine herbivores, but my experience
and observation is that used sensibly softened, organically-growing
plants cause few problems; they do at least contain fibre and some
vitamins, so while not a substitute for marine algae, they are useable
supplements that helps to keep marine herbivores "regular",
and avoiding constipation probably has a big impact on how well such
fish absorb nutrients from their other meals. In other words, even in
England, it should be possible to get ALL the foods your marine fish
need from the supermarket, even if your local pet shop doesn't
carry everything you need!>

Blind Dog Face Puffer 11/14/10
I have a problem with my dogface puffer. He seems to be blind.
<Does happen in captivity. Perhaps nutrition-related>
He has never had a problem seeing anything before. Every time I fed him
he rushed right to the food. Now, it seems like he knows I'm there
but when I drop the food he has no clue! Every time I feed him now, I
have to feed him by hand. It seems he can not see or smell it! I have
to rub the food on his nose, then he swallows it whole! I feel awful!
He was perfectly fine before!
