A Too-common complaint with fancy-round varieties of
goldfish, is the propensity for "gas bladder"
disease... often curable with low protein foods like peas, rice,
less food period, and Epsom salt addition.
- Goldfish need veggies/greens (partially boiled veggies,
thawed frozen peas, etc.)
- Sometimes, too much dry food can lead to constipation
- Dropsy is a condition, not a disease. Dropsy is a build up
of internal pressure that can be caused by any number of
different things. The internal pressure can be caused by gas,
swelling, tumors, constipation, etc.
(infection is sometimes, but not always, the root cause of
these problems). Whatever the cause, the fish will appear
bloated, sometimes to the extent that the scales protrude and
the eyes buldge.

Please help my lovely Shubunkin! 4/24/12
ETA - don't know if you managed to read the email with the huge
pics (sorry about that!), but if so, please note I had written the wrong
nitrate results (I was a bit panicky and did the test wrong - I
thought 0 nitrate was odd!)
<Did see this; and was going to ask how rendered thus>
I have three goldfish, two fantails and a Shubunkin (i know mixing types
is not ideal, but they were urgent rescues, and they came together) and
my Shubunkin has suddenly become very ill. They are in a 50 gallon tank,
with readings of 0 ammonia, 0 nitrite and 5 - 10 nitrate. There was
another very small fantail who died a couple of weeks ago - he had
always had problems with what I assumed was constipation (they lived in
a brewing barrel when I rescued them, so I think he was stunted), and
for months, on and off, he would sink to the bottom of the tank and stay
there for maybe a few days. Because of this I have been feeding all the
fish very sparingly on pretty much just cooked peas, so it seems
unlikely the Shubunkin would be constipated.
<Mmm, can't live solely on peas for very long>
After the fantail died, I did start feeding them flake once a week and
they had sushi Nori a couple of days ago.
<And these don't have much nutritional value either... I suggest you
feed a completely nutritious pelleted food. I use Spectrum, but Hikari
and other brands are good as well>
The thing is, the Shubunkin has started acting just the same as my
little fantail, only it started very suddenly, about four days ago. On
Saturday we noticed we noticed he had sunk into a corner and wasn't
moving, so on Sunday we changed about 30% of the water, cleaned the tank
and ran one of the filter sponges under the tap. He seemed to perk up
then, and started swimming around much more, only I thought he might be
wobbling slightly from side to side. Then this morning before I went to
work I saw him bump into the side of the tank, as though he couldn't
stop in time, but as he was swimming about more, I thought he was
getting better. Then when I came back from work, he was arched over on
his side at the bottom of the tank (I have attached pics so you can see
what I mean - the tank is not as dirty as it looks btw, we missed one
streak of algae and he happened to land in front of it). His scales seem
to be sticking out a bit, too, which again is like the fantail was.
He does seem to be able to straighten out and move a little bit, but it
is clearly taking a lot of effort, and then he tends to flip over onto
the other side and bump his face into the gravel.
<Mmm, this fish looks very emaciated to me. Too thin>
Honestly, I would have thought it would be constipation, but he is a
common goldfish, and he eats practically nothing but peas! With my
fantail dying so recently I'm wondering if there is something contagious
and I ought to move him (the other two are fine at the moment, but so
was he five days ago), or if there is something I am doing wrong that
has made them both ill. If the latter, I did forget to clean the tank
last week, so it was 14 days between cleanings, and it did algae up
quite a lot, could that have caused something so drastic though? I
really hope I haven't done this to him! The only other thing is, should
I have changed the gravel? I have had them for about 10 months, and some
of the gravel is that old, although most was bought 8 months ago when
they got their new tank. Obviously it gets a good hoovering every time I
clean the tank, but could it still be harbouring something nasty?
<Not likely, no>
Anyway, sorry for waffling on - I wanted to give you all the info
Is there anything I can do for him? He is a lovely fish and I don't want
him to die. I thought I'd have him for another ten years yet!
<The sinking pelleted food; perhaps some wafers as well... fed a few
times a day. Bob Fenner>
Re: Please help my lovely Shubunkin! 4/24/12
Thank you so much for replying so quickly. The only thing I could get at
this time of evening was Tetrafin pond sticks, which float. Will these be
<Mmm, no... not likely that your Shubunkin will be getting up to them>
Analytical constituents are crude protein 28% crude oils and proteins
3.5% crude fibre 2% moisture 7%. I've put him in a tub on his own and held
his head so he could reach a couple. Should I out anything else in? Rice
Please believe I didn't do this through laziness. I genuinely thought i was
doing it for the best, and the sicker the fantail got, the less I fed them.
The vet said he was constipated and suggested peas, but I guess i took it
too far and it hurt the non-constipated fish.
<I am a person of "strong intuition". You and I are both compassionate...
from the Latin meaning "to bear pain with"... Your Vet's
suggestion/direction was well intended>
What do you think his chances are?
<Unfortunately not good... but not zero either>
<Certainly welcome. Bob Fenner>
Re: Please help my lovely Shubunkin! 4/24/12
First, thanks for your kind words. I'd hate for you to think I didn't care
about my fish!
As things are at the moment I have him in a Tupperware tub, with some pond
sticks and blood worm floating at the top, and some mashed up rice with
flake squished in at the bottom, which he is pecking at.
Should I leave him in there with the food so he can graze when he has the
energy, or should I scoop it out and put more in in the morning? Should I
put him back in the big tank?
<I'd leave him there perhaps for an hour, then return the fish to its tank,
dump the tub out>
Sorry to keep pestering, but I don't really trust my judgment now!
<Not to worry>
Thanks so much,
Re: Please help my lovely Shubunkin!
Your advice has worked wonders! I put the fish back in the tank last
night, and he started swimming around! He's still a bit wobbly and
disorientated, his tail is flopped over a bit and he rests on the bottom
occasionally, but its definitely an improvement! He can move from one
side of the tank (1 metre) to another and although he was still curving
over a bit last night, I haven't seen him do it at all today.
His scales are still sticking out a bit, though. Is that from
malnutrition too? Kind of like his clothes being too loose?
I have bought him some Tetra Goldfish Gold Japan pellets, which sink and
some Hikari Tropical Algae wafers. Are these OK?
I have put two wafers in (which he has been all over!) and a few
(possibly too many) pellets, which he has eaten a few of. There are
still quite a few pellets on the bottom. Should I leave these in in the
hope he eats more (he likes to chew on the gravel) or scoop them out to
avoid bloating my fantails?
<Leave the food in place for about an hour... then vacuum out>
I know the usual rule is no more than 2 minutes worth, but I wondered if
that still applies when one fish is starving?
I also put in a plant to oxygenate the tank at the aquarium lady's
suggestion, and bits of that have come loose, which he is also eating.
<This is also good>
Thank you so much for all you advice so far, it really seems to have
Re: Please help my lovely Shubunkin! 4/27/12
It's Amy again! My Shubunkin is still seeming a lot better, but I'm a bit
concerned he seems to be spitting his food out. At first I thought he was
just spitting pellets out with gravel, but I put him in the tub again, with
no gravel and he still does it, even with flake, which surely doesn't need
much chewing! He seems to chew for a good few seconds, but then spits a bit
out again. Will he still be getting some nutrients from it?
<Not likely much>
Is he maybe just taking in too much at once and only spitting a bit out?
<Possibly... minnows, Cyprinids, including goldfish, don't have "teeth", but
do rotate food items in their buccal cavities for trituration>
I'm hoping this is
just me overreacting, but if there is a problem I want to nip in the bud as
early as possible.
<Nothing to be done here>
Thanks again for all your help,
Re: Please help my lovely Shubunkin! 4/28/14
I know I'm racking up quite a thread, so I'll try and be quick, but now one
of my fantails is sick! I have attached a pic of him, so you can see if he
is emaciated or bloated or what, and also a close up of his scales, which
are sticking out.
<... looks "depressed"... environmental, perhaps pathogenic cause/s>
He keeps sinking to the bottom (although he is hovering slightly above the
bottom) and occasionally flashes his fins, like he is scared. He also is
doing some clear poos (as is the other fantail, who so far is still ok),
which I thought was bloat, but I don't really want to assume that now!
When he does move he is as fast as ever and doesn't seem disorientated. All
the fish have been a bit skittish the past couple of days, but I thought I'd
just freaked them out because I kept scooping the Shubunkin out.
I wonder if I have now overfed them?
They don't seem to be going for the pellets (I've ordered Spectrum too see
if those are more appealing), so maybe I put too many in. Do I now have a
starving fish AND a bloated fish?
<Do monitor water quality... perhaps you've accumulated too much nitrate...
When, where in doubt (partial) water changes... I don't think this is a
biological disease... as you haven't introduced a vector in recent times.
Goldfish deaths 4/14/12
Thank you very much for all of the help that wwm has given me over the
years, both in the form of faqs and when I have had to email.
<Thanks for the kind words.>
Unfortunately today I write with great sadness, as over the last month,
two of my three lovely goldfish have died suddenly and with little
I moved house 3 months ago, getting two new 120 litre tanks to house my
goldfish, a 4 inch veiltail and 3 inch black moor in one, and my big
fantail in the other.
I had little by the way of problems when first moving, some small
Nitrite issues in one of the tanks, which quickly went away with water
changes and careful monitoring.
A month ago, the black moor started to show signs of Finrot and
streaking in his tail, and before he could be treated, began to curl up
into a c shape, become obviously weak, and float on his side, within 48
hours he was dead.
All water chemistry was within normal parameters, (0 ammonia/nitrite,
around 10-15 nitrate and 7.7-8 ph, with a much higher natural kH than
before the move, the new place seems chemically the idea natural water
for goldfish.) and around 18 degrees centigrade.
<All sounds ideal.>
I do 33% water changes weekly and squeeze the filter media out in
aquarium water every 2/3 weeks, there has not been any possibility for
disease as there has not been any new livestock in years, and
they were fed exclusively on cooked peas.
<Hmm… they do need more than just peas! By all means use peas 2-3
times a week, but also offer a variety of things, including a good
quality Goldfish flake or pellet food.>
I can rule out any chemical interference, as I had not started my new
job yet, and as I was in the house, regularly checked on the fish, and
would have noticed if there was a chemical smell from outside. I
suspected perhaps septicemia and resolved to be much more careful with
any signs of Finrot in future. Last week I noticed my veiltail have
some red streaks in his dorsal fin, and he was accordingly treated with
ESHa 2000, a medication that Neale recommended on here.
Less than a week later, a very similar thing happened, I came in from
work, and he was floating weakly on his side, and was drifting around
the tank, not really able to do very much, and did not want to eat. I
did a 50% water change and medicated him again. Again testing the
water, the quality seemed fine, but again, he only lasted two more days
and died on Friday night. I was prepared to put one death down to very
bad luck, but two deaths with the same symptoms (although I recognise
fish show pain and illness in similar ways sometimes and does not
necessarily mean they died of the same thing) seems to be more than
that. I now only have one fish left, who seems healthy enough in how he
acts, but has some red staining himself in his tail. Am I doing
something massively wrong?
<How long have you been feeding JUST peas? Do wonder if a
nutritional problem is occurring here; i.e., a lack of some essential
amino acid or vitamin.>
It broke my heart to see two beautiful, friendly, playful little
creatures that I have looked after for over 5 years die like that, and
I want to know if there's something I could be doing better? I
realise from my trawling of the faqs over the last few days that red
streaking in fins and tail can mean a lot of things, stress, bad water
although neither fish acted stressed in any way since about a week
after the move, ate normally until they started showing very bad
symptoms, and as I said before, the water quality in both tanks is
similarly fine. Is there anything you can recommend I do in the future,
or ways to cure this staining/Finrot in my fantail other than keeping
the water clean and hoping for the best? Or anything better I
could have done?
Thanks very much for any help you can give to me,
<Most welcome, Neale.>
Re: Goldfish deaths 4/22/12
Hi Neale, thanks very much for your reply.
I had considered a possible dietary issue being the cause, but whilst I
have fed on peas alone for most of the time, I do have flake food, and
New life spectrum, which I read recommended on WWM. <Good.>
The reason why I had fed on just peas was to avoid causing digestion
issues, due to a propensity for being floaty that I had noticed among my
fish. I will take your advice on board and start feeding more of a mix
with that, and have another in depth read of the FAQs. Thanks very much.
<Hope things improve soon! Cheers, Neale.>
Dropsy and Tail Fungus, GF, env., nutr...
First my basic aquarium info:
I have two Oranda goldfish in a 10 gallon aquarium (Yes, I
realize that this is too small.
<And the source of the issues here...>
This is my first time trying aquariums and I didn't
know. They are getting transferred to a 35 gallon in about 3
months when I move). The largest one is about 2.5 inches without
the tail and the smallest is 1.5 without the tail, brought home at the
same time. The aquarium has been running about 7 months
now. My nitrite and ammonia are both right at 0 ppm and
nitrate barely registers on the test kit.
<Nitrate accumulation? I'd keep this under 20
Hardness and kH, both read somewhat low. The pH is just
over 7. My tap water is pretty acidic, and I sometimes use just a
pinch of baking soda for the entire tank to buffer it up a tiny bit (I
was told this would help general health).
There is currently no gravel, and the only decoration is a hide
with no small holes or sharp edges.
They are fed a mixture of soaked/rehydrated shrimp treats and
frozen/thawed/soaked peas every other day.
<See WWM re goldfish foods/feeding/nutrition... I use Spectrum
pellets for my fancy goldfish... Much better, cheaper and much less
Normally they get along fine, but when it's feeding time the larger
one will nip the smaller one. When I noticed this happening, I
started separating him out in a fry net during feeding, which seemed to
work, but large chunks of his tail had been bitten off. This was
several months ago, and he seemed fine. His fins were healing and
even beginning to grow new tissue. Then I came in one day to see
him clamping one of his pectoral fins to his side and found that a
large chunk had been torn off.
<Again... environment... the too-small system>
I isolated him in the fry net for a few days, until he started
to move it freely again. He doesn't seem to have any problems
getting around with it, and you can barely see new tissue growth.
Then, after feeding one night I noticed that he was slightly pineconed;
his scales were ruffled almost like a bird's feathers. I
panicked, did a huge water change, and got rid of all the gravel in the
aquarium (which is much cleaner now). When I checked him in the
morning, he was pretty much back to normal though. That was about
two weeks ago.
Last night I noticed that the pineconing had returned and his tail,
which had been previously healing quite nicely, was starting to tear
along the old injuries. I thought the tearing was just from the
stress of having to use it to compensate for his bad pectoral
fin. He has been in the fry net for the past two days to avoid
the larger one picking on him due to him not being able to swim very
well right now. This morning, the pineconing had receded again
and is currently barely noticeable.
Just within the last four or five hours, though, his tail has gotten
dramatically worse. The normally frayed edges are now sporting
little white tufts on the ends, and the top of his tail (which was
never even injured) has begun to erode, with the same white fuzz on the
edges. He is still active, alert, and ate well last night.
I'm setting up a 10 gallon Rubbermaid tub as a quarantine tank for
him, and putting aquarium salts in it. This was sort of an
agonizing choice, since I've heard aquarium salts are good for the
tail fungus, but not for the dropsy. This thing is moving scarily
fast though, so I'm thinking that's probably what's been
causing the Dropsical symptoms. I can't be 100% sure that
it's a fungus, but I've had to ID fungi before for coursework,
and that's really what this looks like.
Finally, the larger Oranda had a tiny spot of fungus fluff on his tail
about a month ago. It lasted for about three days, with him
shaking it off and it regrowing, and then never came back.
I'm thinking that's how this got into the water.
To make things worse, I'm going to be out of town for the next
week, starting tomorrow (but still able to check my email) and someone
else will be taking care of my fish. I can have them do whatever
needs to be done, but they won't be able to do as much as if they
actually lived here. I know I just gave you the life history of
my fish, but I didn't know what might and might not be
useful. Any help or advice would be much appreciated.

Re: Dropsy and Tail Fungus (forgive me for channeling you, Bob!)
<<Please do>> 3/18/12
I have a question about how much aquarium salt is okay for his
quarantine tub... I saw directions saying 1 tsp per gallon,
but I only used about 8 tsp for 10 gallons in the tub, since I've
also seen directions that advise for less. Is it okay to keep the
salt at that level for awhile? The fungus on his tail is already
less visible, and he hasn't pine coned anymore. Should I keep them
separated like that until I move and can get them in a bigger
tank? It'll be a pain, but I'm willing to do it. I
already change the water once a week (sometimes more), and I've got
the person watching them doing a partial water change in the quarantine
tub every day since it isn't cycled or anything. I'll try and
get some of the spectrum pellets! I haven't seen them around
where I live so I might have to order them. Thanks for the

if needs be to convert from metric units to those favoured in your part
of the world. As Bob F would say, "WWM is best used to help
yourself"… read, don't write; all you're asking has been

Re: Dropsy and Tail Fungus (forgive me for channeling you,

on both WWM as well as other websites, and had seen some conflicting
information (as well as had a hard time finding specific

fungal infections -- albeit rarely -- and they're swimming around

Now, it is true that strongly brackish water can treat some fungal

for this to happen, most freshwater fish will be dead, or at least

from your first message was that all I should do was monitor the NO3
levels in my tank,

directly, and in itself, isn't especially toxic, with levels as of
20 mg/l being tolerated by delicate fish (like Discus) and of 50 mg/l

That is infinitely more toxic, and levels as low as 0.5 mg/l can cause
disease, and above 1.0 mg/l most fish will be severely stressed, if not

are good), and was just curious if there was anything else I could be

time for research.

what'll work best for your fish is reading before you start

spent roughly four hours that night looking through forums and Google
before I sent an email in to this website. I couldn't find
anything that was specific to my problem; People were recommending one
thing for fungus, another for dropsy, and many of the articles
didn't pertain to goldfish in particular, so I didn't know how
well some of the treatments would work on my fish. It was not a
question of me not wanting to look up the information, but of me not
being able to find information that I felt was both pertinent and
reliable. Sorry, it just seems that you got the impression that I
didn't or wasn't willing to put time into looking these things
up, when in reality I sent that email after several days of forum
postings on other sites and quite a bit of frantic, last-minute
research on the topic.

Re: Rolling-over Comet; RMF, anything else
spring to mind? (was: Wonder Shells)<<No>>
Hello, I was wondering what may have caused on of my comet goldfish
about 8 inches long , 11 yrs old, to start becoming constipated, I have
been dealing with it about 1 month or so now, I see him sitting at top
of tank in a horizontal position a lot and this is when I know he has
problems, he will swim funny some too, so I give him a cooked shelled
crushed pea and he will then poo and it is a lot, has a lot of mucous
in it and floats to top, I can get it out very easy. then he is fine,
he is actually good after I give him the pea, today I noticed after
giving him half a pea for 3 days he actually passed some of the
He eats good and acts fine otherwise, should I just make sure he eats a
pea every night, I feed them in the morning but by evening I do this
with the pea, just concerned with giving it every night??
<Sounds to me, Cathy, that this comes under the head of "just
one of those things". Wild Goldfish are mud-sifting herbivores,
and they're adapted to a diet that, in terms of bulk, contains a
lot of mud and indigestible matter.
They sift a lot of this out before swallowing, but some is swallowed,
and along with all the cellulose within the plant material itself, they
end up having to deal with what we'd consider a gritty, muddy sort
of diet. So, evolution has given them a gut that handles that sort of
thing well, but captivity and the sort of diet we normally provide them
-- flake -- means that they're not dealing with anything like as
much indigestible material.
The bottom line is that without enough fibre, they're prone to
constipation, and in Goldfish this often reveals itself through odd
swimming angles. Think of them as having extra weights inside their gut
that cause them to roll over like an unstable boat.
You're doing all the right things, but you may choose to go
further: feed exclusively greens, e.g., peas and pondweed, except
perhaps offering high-fibre wheat germ pellets once or twice a
Also wondered if I can use a double outlet aerator for my tanks,
<So long as the water currents produced aren't buffeting fish
around the tank, you're probably fine. Avoid supersaturating the
water with oxygen though: if bubbles stick to the fish, to the glass
walls of the tank, etc., you're overdoing it.>
I would use the one aerator base divided into two twenty gallon tanks,
right now I am using Stella 40 and don't seem to put out enough for
them, I added another to each tank today, added 20-30 along with the
one they have already Stella 40, it is making nice bubbles and they
seem to like it, don't know if this is okay or not, don't like
having to use extra plugs, this is why I want to know what size pump
can I buy with double outlet for them, Also does increasing air hurt
them or the water parameters??
<Nope, not as such.>
I am leaving for a bit and want to make sure all is good for them while
gone and of course in general
<Hope this helps, Neale.>
Re: Rolling-over Comet 11/23/11
Thanks so much I feel better, Looks like the one that always sits at
top is now staying all over, might have needed the extra air! I will
see later, anyhow as far as I can tell with using 4 air pumps, 2 in
each tank rated for a total of 60 gallons, they are in 20 gallon tanks,
no buffeting, I might need a bigger aerator pump?? I want one with two
outlets to avoid using all these stones and plugs!!
<Air pumps need maintaining. When did you last replace the
diaphragm? If the air pump has been running for a few years, the rubber
diaphragm could have perished to some degree, so the "puff"
from this air pump would be much lower than it should be. New
diaphragms are inexpensive and easy to install, at least for the good
quality air pump brands. Cheers, Neale.>
Re: Rolling-over Comet 11/23/11
So no matter what I buy (rating for air pump to aerate) I don't
need to worry about over doing it with too much oxygen, as long as I
watch for bubbles on the glass or fish? So they cant really have too
<No. The fish don't like bubbles. So be sensible. Aerators
don't add oxygen to the water. So more bubbles DOES NOT mean more
oxygen. Here's how air stones work: As the air bubbles rise, they
pull water upwards with them.
This helps circulate water around the tank. Moving water from the
bottom of the tank means oxygen is better distributed around the tank.
But here's the thing: filters and powerheads can do this better
than air stones. That's why you'll find modern fishkeepers
don't use air stones that much. It's often better to add a
small extra filter, and thereby increase water quality as well as
oxygenation, than to spend the same amount of money on an air pump,
tubing and air stones. In many ways air pumps are a hangover from the
past. Useful, yes, but not necessarily the best way to improve
circulation around the tank. Much better to ensure your filter provides
good turnover rates, which in the case of goldfish, should be around
6-8 times the volume of the aquarium per hour, e.g., 330-440
gallons/hour for a 55 gallon aquarium.
Fantail clear poo 7/10/11
I have recently acquired some goldfish that I unfortunately know
very little about. The circumstances are that I work at a letting
agency and some tenants moved out of a house, leaving behind four
goldfish in a bucket. Fortunately they also left a tank (full of
dead guppies when we found it), so I took home fish and tank and
am looking after them as best I can - a lot more complicated than
I first thought, but I have got very attached to them and want to
do what's best for them.
As far as I can tell there are three fantails and a Shubunkin
(the Shubunkin is pretty chilled out though, and doesn't
bully or hog the food).
One of the fantails is very small (2 inches minus the tail), and
without knowing anything about him I've no idea if he's a
juvenile or really stunted. The other fantails are at least twice
the size. For the past three days the little fantail has been
doing long strings of poo with clear sections in it, which
I'm a bit worried about. I read that it might be overfeeding,
and have not fed the fish for the last three days, but all that
has happened is that the poo is now completely clear. Another
weird thing is that he only seems to do it in the evenings.
Finally, and possibly this is unconnected, I've also seen him
swimming vertically a few times. I didn't think this was a
problem, as he seems to get about OK and doesn't do it very
often, but I've heard people talk about 'vertical
swimming' as a thing to be worried about.
I've checked ammonia, chlorine, nitrite, nitrate, hardness,
and pH and everything is normal. The tank is on the small side at
14gallons, but they will be moving into a new 60 gallon one as
soon as I have finished the fishless cycle.
I have attached a photo of my fish and, um, his poo, so you can
see what I mean. Would you be able to tell me if there is
anything wrong, and if so how to treat it? Would I need to
separate him before treating him? Also, if you can tell whether
he is young or stunted, I would like to know that too.
Sorry for such a long and rambling email, but I don't really
know what is relevant and I don't want to miss anything out
if it will help him!
<Hello Amy, and thanks for deciding to take care of these
abandoned animals. Generally, transparent, stringy, pale faeces
from Goldfish indicate nothing terribly serious beyond
constipation. This is easily remedied by providing more fresh
green foods and less dried food. The classic food for Goldfish in
this regard is plain vanilla pondweed, as sold in pet shops by
the bunch. Put in the tank, don't feed the Goldfish
otherwise, and the Goldfish will graze on this stuff quite
Alternatively, things like blanched lettuce, cooked spinach and
cooked peas work just as well. After a week or two of just green
foods, fold in flake and other dried foods into their diet
perhaps 4-5 days per week, the other meals being fresh greens of
one sort or another. You can buy high fibre goldfish foods --
often called wheat germ or winter food -- and this can be used
instead of flake if you find your Goldfish constantly producing
excessively long and stringy faeces. In any event, read here for
more on diet and basic care:
It's unlikely your Goldfish is sick in any serious way, and
odd swimming is likely caused by constipation. It's best to
keep Goldfish together rather than to try to separate them out
into hospital tanks because they're very social fish, and
kept singly get unhappy. Maximum length for fancy Goldfish varies
significantly, and growth rate, though continual through life,
slows down as fish mature. So if a fish isn't kept well
initially, it may never reach full size, even if moved into
spacious and healthy quarters. Even so, you should expect even
"small" Goldfish to get to about 15 cm/6 inches within
3-4 years. Cheers, Neale.>
Re: Fantail clear poo
Thanks so much for your advice. The fish have been on a pea and
cabbage only diet for the past two days and have been doing some
*extremely* healthy looking green poos! I never thought I would
become so obsessed with goldfish poo...
<All sounds very promising. Good luck! Neale.>
Re: Fantail clear poo
I wrote to you a couple of weeks ago about my little fantail fish
and his clear poos. I have been feeding him only vegetables
(peas, cabbage and courgette) for the past two weeks, but he
still keeps getting long strands of mucus hanging out of him.
<If the fish is otherwise healthy, don't worry too much.
Fancy Goldfish are sometimes prone to chronic
Also, he was acting in a worrying way for a couple of days last
week - he kept swimming to a couple of inches below the surface
and then just floating there.
<Odd, but may be indicative of warm water this time of year
(less oxygen in warm water); water quality issues (check nitrite
is still zero, and do a big water change, perhaps 50% and see if
that perks him up); or water chemistry problems (Goldfish
generally dislike acidic conditions).>
Then his head would sink down so he was vertical and he would
just hang like that for ages. Also he kept doing big gasps and
his fins would stiffen (is this fin clamping?). But that only
lasted for a couple of days and he has been fine for about a week
now. I change half of the water every three days while
they're in the small tank, so maybe that helped?
<Goldfish become steadily more prone to "malaise" in
small tanks, and short of upgrading the tank to something
sensible, there's no real cure.>
Could the mucus be a parasite or something, or should I just
stick to the greens-only diet until it goes away? He does seem
fine otherwise, but I am a bit worried about the mucus, as he has
been like this for a while.
Also, is it ok to leave a cabbage leaf in the tank until it is
I have given them a cabbage leaf a couple of times and they shred
it in about two hours!
Intestinal prolapse - please help!
I am so sorry to bother you again but my fish woes seem to happen
all at the same time even though my fish are in different
My beautiful two year old Demekin has prolapsed intestinal tissue
(it looks like a opaque white bubble). This happened about 8
months ago to my young black moor and the fish did recover
(albeit with lingering balance problems).
<Not an uncommon situation unfortunately>
I have moved the Demekin's tank mate in with another fish so
that he won't be pestered. I have turned out the light and
have added Epsom salt at 1 1/2 tablespoons per 10 gallons. Is
this enough Epsom salt?
Is there anything else I can do?
<Good water quality...>
I am afraid to try feeding the fish a pea for fear that it will
not be able to pass and will rot in the gut.

I just did a water change and gravel vac yesterday so the water
I managed to get a photo- it's not the greatest but it was
difficult to hold the fish and the camera at the same time. It
does not show well but the prolapse extends about 2 to 3 mm. I am
sick with worry... thank you again for your patience and your

re: Intestinal prolapse - please help!
Thank you Bob:
I tried a small, chopped pea but the fish is on the bottom of the
tank and isn't interested in eating. It is opening and
closing its mouth regularly but is not fin clamping. The prolapse
has not gotten any worse over night, which is heartening. It
looks like a clear, whitish bubble- I will monitor and

When I returned home from work today the prolapse had turned from
clear to reddish-purple and the fish is still on the bottom of

Intestinal prolapse worse- HELP!!!
It is no longer a time for patience. Please, I MUST do something
for this fish if there is any chance at all that I might save
it's life. It is still gasping and the prolapse is worse and
now: I can no longer see the anal port as it is obstructed by

There is no chance that the fish will eat- I looked through WWM
for other cases and some suggested to feed Metronidazole but this
is not an option.
Would Met in the water help in any way?
<No. Toxic, of no purposeful use here>
I know that people have tried to relocate the prolapse and one
man aspirated successfully but these don't sound like good
options- desperate measures perhaps. I would do anything to save
this fish- he is not looking very good at all and I am just
Bob, are either of the above even viable options? Is there any
chance that aspiration might help clear the blockage enough to
allow feces to pass or do I have to consider euthanasia?

I am a wreck just thinking about it...and I have to be at work in
less than an hour...
I attached a photo of the prolapse today.
Most sincerely: Gina
<As sincerely, RMF>
re: Intestinal prolapse worse- HELP!!!
I will keep adding Epsom salt but I think I may have to
euthanize. The fish was swimming frantically sideways just before
I left for work then righted himself and was sitting on the
bottom. I am terrified to do so incase he might recover but
can't leave him suffering, either.
Okay, I am typing this at work and will start to blubber like a
baby any second now... so thank you again for your help!
<Don't give up hope Gina. "Saying no" closes
your mind and heart to infinite possibilities. B>
re: Intestinal prolapse worse- HELP!!!
Thank you for you kind words and advice. I am very sorry to say
that the little fish did not recover. He died while I was at
work. I am very heartbroken- he had real character and was
trained to do several tricks.
Two years ago I would have thought fish were boring and rather
prosaic but now I know better.

Black moor with digestive troubles
I have a two very small black moor goldfish in a cycled 20 gallon
Though they are fed a diet of homemade gel food which is made mostly of
fresh vegetables it seems one has developed a digestive problem. The
fish in question is the larger of the two and the fastest swimmer: he
often reaches the food first.
He has developed what I think might be a prolapsed anus, which I
understand can result from a large intake of food and can result in a
bacterial infection. The prolapse is not severe, but as of this
afternoon the area circling the vent looks very red as if it were
bleeding. I have added some Nitrofurazone to the water and do have some
Metroplex that I can mix with the gel food if you feel this would help.
The fish is active, happy and still eating but the region looks very
sore. The fish is also showing slight beginnings of fin rot along the
edges of his caudal fins.
When I first purchased this fish (about two months ago) he had long,
white stringy feces which I treated with Metroplex. I am wondering if I
halted treatment too soon and this might have contributed to the
Is there anything else that I can do for this fish or anything I should
watch for? He is sharing a tank with his mate as they have been
together since I purchased them and if the fellow is contagious it is
already too late to quarantine.
I normally change a small portion of the water two to three times a
week and will resume doing so once I have completed treatment with the
Nitrofurazone. I have also taken steps to preserve the cycled media by
removing it during treatment. Any advice would be gratefully
Thank you for your time and assistance:
<Hello Gina. A prolapse should recover under its own steam given
good conditions. Antibiotics will fix the immediate problem, and Epsom
salt may help speed up recovery. But otherwise there's very little
you can do.
There's a photo of a prolapsed anus here, about halfway down:
It's worth remembering the prolapse isn't a disease, but a
symptom of a bacterial or microbial infection of the lower gut.
Metronidazole and one of the Nitrofuran medications will provide the
best combination here. Cheers, Neale.>
Re: Black moor with digestive troubles 1/15/11
Thank you Neale, for both the advice and the photo link.
I guess I didn't clear the infection completely the first time. I
will commence with the Metroplex at once. Is it safe to employ Epsom
salts while treating with medications?
<Not just safe, but recommended in situations like this. Cheers,
Re: Black moor with digestive troubles 1/21/11
Hello again, Neale:
Thank you for the advice- the prolapse and the bleeding seem to have
healed up but the fish is still exhibiting signs of an internal
bacterial infection. I have completed the cycle of Nitrofurazone: I am
still adding Epsom and using Metroplex. I stir the into food paste and
feed directly to the fish. It has been 5 days now and there is no sign
of this internal infection clearing.
<I don't know this Metroplex product; what's in it?>
I had this trouble before when I tried to clear the same type of
infection (characterized by long, white, trailing feces). I had the
fish on Met for about two weeks and it seemed to clear up somewhat but
the problem was not fully resolved.
<Metronidazole is that standard medication for Hexamita, which is
the disease that usually produces long white faeces. But the white
faeces are merely mucous, a sign the gut is being irritated. Worms
might do the same thing, in which case an antihelminth will be
Is it safe to keep the fish on Metroplex for longer than two weeks or
should is there a better medication?
<Should be harmless, but do consult the information that came with
I do like the Metroplex because I can feed it to the fish directly: I
have host of other meds including Medigold, which I don't like as
the pellets are so hard, even after soaking.
Re: Black moor with digestive troubles
The Metroplex is Seachem's new name for their Metronidazole so as
you say it should target Hexamita. It doesn't actually say how long
one can use the product safely in one treatment cycle, tough. I can
write to them to find out.
You mentioned antihelminth meds- do you have one that you
<If I recommend them at all, I recommend people get advice from a
vet, because it helps to get the right dosage for the body weight of
the fish concerned, and not all work equally well. But in the US at
least there are over the counter options. Among the drugs used to treat
fish are Levamisole, Piperazine, Praziquantel, Fenbendazole and
Flubendazole. Of these, only Praziquantel and Flubendazole are widely
available as over-the-counter medications. Examples of medications
including either Praziquantel or Flubendazole include Sera Tremazol,
Solupraz and Wormer Plus. Antihelminths do not necessarily kill the
worms, and in some cases only paralyse them, which results in them
being pushed out of the gut and
into the aquarium (which the aquarist will see as the pink or white
worms emerge and detach from the anus). Within 24 hours of medicating
the substrate should be thoroughly cleaned to remove the worms.
Normally three treatments are required, each one week apart. Ideally,
throw out the old substrate at this point and replace with new.>
Re: Black moor with digestive troubles 1/23/11
Ah, good! I do have several of the medications that you mentioned in my
fish medicine cabinet- though I am reluctant to treat the fish unless I
am sure that it needs the meds. Should I continue to treat for Hexamita
and if the fish still presents with trailing feces try the antihelminth
<I'd finish one course of medications, wait a week so the fish
can recover a bit, then start the next.>
I should mention that the fish has a tank mate who is not symptomatic
(so perhaps it is not worms). I haven't separated the fish as they
were purchased together so anything contagious is apt to be shared.
I am actually in Canada and sad to say there is only one vet who treat
fish in the entire province of British Columbia- he is actually retired
but is on call for the Vancouver Aquarium. I know several marine
biologists which does not help much. Sadly, most people here don't
want to spend the money on small animals or fish. I am pretty much on
my own for diagnosis and treatment so I am very grateful for this
wonderful website. It has been an invaluable resource and I have to say
that I have often given advice to people in the LFS who are having
trouble with their goldfish when the staff at the store could not help.
I always direct people toward this site and its excellent articles.
<Glad we've been able to help, and thanks for the kind
Regarding treatment of the fish, I do have a decent postal scale with
which I can weigh him if I need to calculate dosage. As I type he is
staring at me, awaiting his morning feeding so I have to say his
appetite has scarcely been affected throughout this ordeal! As I am on
day 7 of treating with Metronidazole I will continue for a full course
but if the problem still persists I hope you will not mind if I seek
your assistance yet again

Fish with blockage in throat or intestines
I have a young lionhead fish who appears to have an
intestinal blockage. I believe that he ate a piece if pea that, though
chopped into smaller bits, was too large for him to swallow. This
occurred yesterday evening (October 13th at about 5 PM). It is now over
24 hours later.
He has not been able to ingest any food- he dives after the food
enthusiastically but then cannot swallow. He ends up spitting out the
He also has not defecated.
I have picked him up and looked down his throat- it looked clear and I
suspect the blockage is deeper. Is there anything that I could do?
Would Epsom salts help?
<Hello Gina. Epsom salt relaxes muscles so might help. But otherwise
there isn't anything you can do here. With luck, things will
improve in time.
Re: Fish with blockage in throat or intestines 10/18/10
Thank you, Neale:
Just wanted to let you know that I tried Epsom salts and they did the
trick- the little fish was finally able to eat today!
<Thanks for letting me know. Have fun! Neale.>
Upside down GF, reading 10/6/10
My goldfish swims upside-down at the bottom of the tank or simply lies
upside-down. He/she has been doing this for the past week. The goldfish
is one year old and a classroom pet. My students are anxious
and would like to have some info about what is causing this.
<Please have them read here:
and the linked files above. Bob Fenner>
Indoor goldfish, hlth., env. or nutr.....
Hi, I have a cold water tank fish that's approx 4 inches in length
and about 5 years old. The last four days he has started to spend the
majority of his time on his head (vertical) at the bottom of the fish
tank and sometimes almost upside down but more vertical. He still
manages to swim around but soon as he stops he goes vertical again, he
is not eating very well but looks well in his appearance..?
Please could you let me know if there is anything to help him..?
<Could be one of two things. Constipation is one common cause of
swimming problems. Feeding just dried foods isn't acceptable. There
needs to be some green foods on offer. Read here:
The other common reason Goldfish suffer this way is poor water
Goldfish need to be kept in tanks at least 115 litres (30 gallons) in
size; unfortunately far too many people try to do otherwise. Given your
Goldfish is very small for its age, I suspect this could be the
problem. A 5-year old Goldfish should be around 20 cm (8 inches) long.

Goldfish... fat 9/22/09
My goldfish, who is about three or four years old now, has recently got
very, very fat. I have looked it up on your site, but the fish is not
floating or anything like that. Other than the large tummy, it's
normal. My other goldfish is completely fine and they eat the same
amount of food. The swelling is slightly larger on one side, and
it's not round, but slightly bumpy. I'm not sure what is wrong
(hence my asking you), but I'd really like the fish to look and
feel healthy again.
Thank you =]
<Hello Sasha. Well, there are three likely problems here. The first
is constipation. Not all constipated Goldfish float upside down!
Indeed, most don't. One sign of constipation are long faecal
threads ("strings") hanging from the anus. Swelling is
another. If you haven't fed your Goldfish green foods, then
there's a good chance this is the problem. Stop feeding
flake/pellets for a while, and offer cooked peas or a bunch of Elodea
Another option is simply the fish is fat, in which case, feed it less.
Cut down the food, and offer the same green foods as you would for
fixing constipation. After a few weeks, it should look thinner.
A third option is some type of abdominal infection, typically called
"Dropsy". This causes the scales to lift from the body, so
that when viewed from above, the fish looks like a pine cone. It's
very difficult to treat
this, and antibiotics are usually required. Adding some Epsom salt will
help relieve the swelling, but it doesn't directly fix the
Hope this helps, Neale.>
Thank you so much =]
I know it's not 'Dropsy', as there are no scales lifted,
and it looked fat all the way around and from above, below,
I'll definitely use your advice and feed them no pellets, just
peas/planty stuff =]
<Most welcome. Cheers, Neale.>
Bloated fantail Hi guys <Hi, Shelley, Sabrina here
tonight> Thanks for being there to answer our questions.
<You're welcome, of course! We love being able to help.> My
fantail Co (yes I have names for them all: Mo, Co and Calico) has
gradually become bloated underneath and to the sides, but more on one
side than the other. The skin appears paler and stretched. This has
been happening for a month or so. Just the last week he has taken to
"swimming" upside down at the surface of the tank. I usually
feed dry flakes, with frozen bloodworms once a week. Co is greediest of
all, and chief beggar of food. I assume from reading your other website
answers today (I only found your site today) <Well hey, then,
welcome! Enjoy!> that he has become constipated from eating the dry
food and this has resulted in a swim bladder problem. <Sounds quite
possible.> I will definitely change their food when they are back on
it. <Great! More greens, less dry stuff.> I read another website,
and stopped feeding them all four days ago, and fed some green peas
(but they don't seem keen on them, and they took days to
disappear.) <Try frozen peas (thaw them) and squeeze the
'guts' of the pea out of the shell (discard the shell), they
might be more apt to eat them if you prepare them so (don't know
how/what you used before). Failing that, try canned peas (try to get
'em without salt, or if not, then rinse thoroughly) and again,
squeeze the 'guts' out of the shell. I'd be impressed if a
goldfish refused that! You can try brine shrimp (frozen or live), as
well, as that may help some, too. And please do not leave the peas in
for more than a few hours - if they don't eat 'em by then,
assume they won't be eaten.> Also I don't know whether Co
ate any or whether it was the others. I also checked water quality etc
so no issues there. <Ammonia, nitrite, nitrate, pH?> Co seems to
be a little thinner, and "floating" less then he was, but
I'm worried about the other fish (who now also haven't been fed
for 4 days). <They're probably fine. Try the brine shrimp if the
peas fail again, and they'll probably all accept that quite
readily.> Do I need to set up a QT tank to isolate Co? All I have is
an old goldfish bowl, which doesn't have any filtration, aeration
etc - would this do? If I do separate him, should I add Epsom salts or
anything else? How long should he be without food, if he stays swelled
up? <If you can isolate him yes, but he'd need aeration. Even a
small-ish Rubbermaid container or bucket (or the fish bowl, if the
goldfish isn't too big) would do the trick in a pinch, and an
inexpensive aerator will be an invaluable device if you ever have to
quarantine again, certainly worth the low expense. Epsom salts at a
rate of 1 to 2 tablespoons per 10 gallons of water will help, and keep
trying the peas and brine shrimp. He should accept them, if he's
hungry.> How long does it take a fantail to recover from swim
bladder problems? <Well, that's tough to say. Sometimes a fish
recovers from problems like this completely, and is healthy and
happily-ever-after-the-end. Some fish never fully recover, and float
(or sink) for the rest of their (often short) lives.> Does one bout
of it mean he will have a tendency for the rest of his life (that's
if we pull him through this time)? <Quite possible. Feed a better
diet, and you'll be on safer ground.> Sorry for the million
questions, <Don't be! This is why we're here!> but
I'm fond of the little guy and would like to fix him up. Shelley

My daughter received a black moor for her b-day last week.
<sounds like the fish came unexpected. Is it living in a bowl? Or in

high waste producers & can poison themselves w/their own waste. Did
you use dechlorinator?> He will come up and eat the flakes I give
him but a few seconds later spits them back out, I tried changing foods
to tiny pebble food, but he does the same thing, I'm very surprised
that he's still alive, he is moving much more slowly. <Animals
won't eat when feeling poorly. This could be caused by poor water
quality, or just stress from being in a new home. Make sure you take
out any uneaten food, as that will just add to the problem. You could
try some of the tastier frozen or a higher quality goldfish food.

Goldfish Swollen behind its Gills What a truly amazing site
you have! I'm overwhelmed by the amount of knowledge here, but in
all my efforts, I was unable to find anything describing the problem
with one of my goldfish, so I thought I'd write and see what you
have to say. <Okay> I have eight fancy goldfish in a 55 gallon
tank. One is about five inches in length, one about four inches, and
the other six range from two to three inches. I maintain a clean
environment for the fish, and feed them pellet food, according to the
recommendations at the pet store. <Not to exclusion I trust. Dried
foods are problematical with fancy goldfish... and I hope you do
sizable weekly water changes...> First, some of my fish tend to
float after they eat. It doesn't happen right away, but a couple
hours after they eat, they float. They're still upright, not
sideways, or upside down, as I've read in many other cases. They
don't have a problem swimming, or eating, and they do return to
their normal buoyancy after a few hours. I've seen this come and go
with several of them. Is there a swim bladder problem here, or is this
something different? <Something different. The food> Finally, one
of my fish, a blue fantail about 2 1/2 inches long is not well.
Immediately behind the gills on both sides, is a small oval shaped
swollen area, the length of the gill, and about 1/4 inch wide. The fish
seems to be breathing okay, however, I would imagine it's a bit
labored. He's still just as friendly, active, and hungry as the
others. Whatever is swollen is under the scales, though they don't
seem to stand out much. I do believe one of the scales was lost on one
side as that side appears bruised. Is this related to gill disease?
<Maybe, maybe not. I would not be concerned with this being a
problem, but I would "do something" in the way of adding
fresh and frozen foods in place of the all-dry regimen> I don't
believe dropsy is involved, because the rest of the fish seems to be
normal. <Not dropsy, but the current feeding practice will lead to
other maladies> Any ideas, and suggestions for treatment would be
greatly appreciated. I have a hospital tank I use to treat sick fish,
so that's not an issue. I just need to know how to treat it. Better
to know, than to use a random medication hoping it works. Thank you for
your assistance. David C. Ware Professional Computer Nerd <Ha! No
worries. The "floating" and likely the swollen area issue
will be "solved" soon by feeding frozen/defrosted foods,
par-boiled vegetables, cooked rice, frozen/defrosted peas... Feed the

Dinner-plate Size Redcapped Oranda HELLO : <Hi Magnus to
help> I have read most of the Q&A and it has been very helpful
as far as making me feel as if I were doing the best possible for our
fish. <That is what we hope our FAQs can do.> I have even called
emergency vets to get suggestions. Believe it or not I have even given
her an enema (don't ask). <I won't... though, I'm
struggling not to get a bad mental image.> Now we find our
self's wondering if we are doing the right thing by trying so hard
to keep her going. She seems to be suffering from swim bladder probs.
SHE has stopped eating unless hand fed and is not pooping, along with
floating upside down at the top of the single fish 40 gal. home. <At
least she is not in with other fish that can pester her. if she were
with other goldfish I doubt she would have made it this far.> We
have been using the salt baths, Epsom salt tank water, brine shrimp,
aquatic plants, and the peas. She seemed to have tried to poop
yesterday, but it was a hollow tube with very little noticeable food
partials in it. We believe she has possibly swallowed a rock and is
unable to pass it. <If that is the case then there is very little
you can do for a goldfish, aside from surgery. They really aren't
able to pass stones, some goldfish can bring the stones back up their
throats, but I have never seen this happen, and only heard about it
from unverified sources. The sad fact is that if the fish has swallowed
a stone, and hasn't passed it already, it most likely has an
intestinal blockage. And an intestinal blockage is not something that
can be fixed (without surgery). You can give it a little more time, but
I'm sad to say that I'm not sure if there is anything you can
do to help your fish.> My wife and I and the kids have all cried,
been angry, and stressed. We want to know if "FANCY" is
suffering even though I could not bring myself to putting her out of
her misery without feeling terrible for the next year or so. <That
is quite understandable, but remember that if the fish is starving or
having toxins build up in her system then it can't be called a good
life.> The reason we are having so much difficulty is because we
have had FANCY for almost three years and she talks to us and has a lot
of personality. <I know exactly what you mean, my oldest goldfish
has been with me for years. I can't imagine not having him great me
in the morning (his tank is in my room).> From tip to tip she is
approx. 8 inches. <wow, for an Oranda she is pretty big. It seems
you have taken the best care of her to get so big!> The cable guy
say's she would be good on a shish kabob. <sounds like a nice
guy... so nice that I would probably switch over to DirecTV...> The
heart wrenching thing is that she still try's to swim around and is
very much wanting to live! We hope you might have a suggestion since
this has been going on for nearly three weeks. PLEASE HELP! SINCERELY
FANCY & FAMILY <You can give it more time and try to feed her by
hand, but it's only prolonging the problem. You are probably right
that she has a blockage in there, and trying to get the blockage out
(aka squeeze her or try to force the stone free) will more than likely
damage her internal organs. If this persists you will more than likely
see a decline in her health. Floating and unable to right herself will
slowly work away on her, and she will most likely succumb to a
secondary infection or worse case she has a rupture in her digestive
system. Either way, it will not be a good thing. I wish there was
something I could tell you to fix the problem. But what you have told
me seems to point towards something that isn't fixable. You can
give in a few more days and see if she does pass it, or that she does
expel waste then it might show signs of hope... but please don't
hold out to long for that. If you really want to spend the money, you
can look around for a vet that specializes in fish and aquatic life
(talk to your local zoo or aquarium they might know of one) and see
what they think. Perhaps they can get an x-ray of the fish and
determine the problem. But, this is not going to be a cheap endeavor,
it will most likely cost way more than the fish was initially worth (as
for the emotional worth, that is up to you.) If you don't feel that
the fish is getting better then you should bring yourself to think
about euthanize the fish. There are many methods, the method that I had
found to work the best, with the least amount of pain was to place the
fish and a comfortable amount of water into a plastic bag then place
the entire bag into the freezer. The fish will slowly slip away as the
water gets cold. The fish is gone long before the water freezes and any
sort of ice can form (in or on the fish). I do hope that the fish does
somehow recover. I'll be wishing for it. I would hate to loose any
of my goldfish, let alone my large ones I have had for a while. Good
Goldfish activity levels I have 8 smallish goldfish (various
kinds) in a 96 litre tank - all healthy except one which I suspect has
swim bladder problems .... I am going to take advice from your FAQ
section and amend diet. <Hopefully the diet switch will be
what's needed to help the fish!> However, at the school where I
work, the tank is slightly smaller, and holds only 2 fairly large fancy
goldfish. The rest of the tank is quite full with plants ... so much so
that it can be difficult to locate the fish. <Heavily planted tanks
are quite nice, and goldfish seem to be happier in that case. Goldfish
are bred from carp which like to be in muddy waters, and heavy with
plants. gives them place to hide, and a good source of food.> The
fish do not seem very active (I have not seen them at feeding time). Do
you think they need extra care? <Most likely not, Goldfish don't
need to be extremely active, if they are fed well, and healthy then
most times you see them just sort of "chilling" in the tank.
If they show signs of illness, or swelling then I would be concerned.
But, it sounds like you just have to well fed, and some what lazy
Goldfish. I have a few that are exactly the same way. -Magnus>
Upside down goldfish Hi! I don't know if you've
addressed this problem in your sight before but my goldfish has been
acting very strangely. There are two that are swimming upside down and
I don't know why. They always stay at the surface of the tank. At
first we thought it was cold so we put a heating generator in the water
for it to warm up because the weather was turning colder. The fish are
literally in a vertical position swimming around the tank as though
there was nothing wrong. I'm afraid something may be happening to
them. Could you please tell me what's wrong? Anna Doan. <Yes...
this "syndrome" is borne of two circumstances, genetics and
diet... some goldfish varieties have been bred over generations such
that they easily lose orientation... especially in face of being fed
too much in the way of "dried foods"... At any length there
is some discussion of this archived on the www.WetWebMedia.com site on
the Freshwater subweb, under Goldfish Disease (many FAQs and Disease
article on them). Your fish will likely respond positively to being
treated with Epsom salt, a change in diet, possibly the addition of
some palatable green plants (like Egeria/Anacharis), and maybe the
lowering of the water level in their system. Please see WWM re. Bob
Up With Chuck! Dear Chuck Thank you very much for the advice.
I don't know exactly where to find Spirulina flakes. I went to
PetSmart but they don't have it. < Check around at other pet
shops or regular tropical fish stores. You may need it in the
future.> My fish is doing better now. You have to see him, he is
happy swimming around and going easily from top to bottom. I decided to
change the water and I put some Epsom salt in it. (1 tablespoon per
gallon) I gave him only peas today and he was happy with it. The other
one doesn't seem to like them very much but he ate some. Because
both fish are in the same aquarium, do you think is bad for the healthy
fish to have the same diet? < Peas by themselves may not be good
over a long term because they may not contain enough protein for your
fish to replace damaged tissues and to grow. There are many fine
goldfish foods on the market. Brands like O.S.I., Hikari, and
Marineland have very good foods that are well balanced.> The healthy
fish has done some white poop today. Is it normal? < The fecal
matter from your fish is a indication of its diet. A long stringy
translucent feces is usually an indication something may be wrong. But
your fish sounds like it is normal.> And if I didn't find the
Spirulina flakes soon, could I start to gave them goldfish flakes
instead? < Make sure you get a good quality flake food and not the
cheapest one you can find. Try feeding a couple times a day with
smaller helpings instead of one large feeding a day.-Chuck.> Thank
you very much for your help - Patricia
Sick Moor Hi Gwen, Thank you for writing us back. Our fish
tank was an inheritance...I am more of a dog lover, but I have grown
very attached to our black moor since having it for a year now. Since
writing you, I followed through on the steps when signs of distress and
disease show. It has helped tremendously. I have also made a point to
read more about the fish and the upkeep of eclipse aquariums. Our fish
is now swimming around like normal, still eating, and seems to be doing
fine. However, I am concerned about the deterioration is his fins. The
very tips of the fins have small holes in them. Also, his bowel
movements are now up to every day since the cleansing of the tank.
Yesterday, it was more clear and thick instead of the light brown
yellowish color. Is that a bad sign? My last question for you...how
long do I leave out the carbon filter when I am treating him with
medicine? Thank you much, Eeon <<Dear Eeon; Glad to hear! The
fins will take some time to heal, up to a week, maybe more. Keep doing
the water changes to get the quality as high as possible, and feed him
the good stuff, Spirulina flake. Goldfish's bowel movements can
change when their diet changes, or water quality. Do not fear, he
should do just fine now :) as long as the clear poop stops in a day or
two. Poop can be a disease indicator, but don't overreact if it
changes color now and then. Leave the carbon out for the duration of
the treatment. You can put it back into the filter when the treatment
is done, and a water change at that time will help as well. Half the
battle is good water quality :) -Gwen>>
Goldfish Waste Color In a site on buying a goldfish it said
that the waste should be dark in color not light. Why? <<Hello.
Goldfish waste is generally the color of the food they eat. Long,
stringy, light-colored waste can indicate an internal bacterial
infection. Watch the fish you want to buy to see if they have trouble
swimming properly, if they gasp (breathe too fast) or if they seem
lethargic. Fancy goldfish are susceptible to many problems due to their
compact body shape. Feel free to read our Goldfish FAQ's here at
Strange behavior in Goldfish I have 3 goldfish , I have had
them for 10 months , they were about 1 1/2" long when I bought
them, everything was normal till this week, one of them is acting
strange, hiding and laying on its back and when you probe him he rushes
around hitting the sides and splashing the surface and then retreats to
hide in a log or foliage. hope you can help me. thank you Bill Pich
<Hi Bill, if there are no other signs of illness (white spots,
fin-rot, body swelling) then I think that your goldfish might be
suffering from a swim bladder problem. There are a number of reasons
why the fish might have swim bladder disease. 1.A virus or bacteria
that attacks the air sac which causes inflammation and makes it
difficult for gasses to diffuse across. So, the fish is stuck at a
specific buoyancy. This is why water quality is so important.
2.Anatomy. The ornamental goldfish that are breed today are predisposed
to problems with the swim bladders. This is because threw years of
breeding the normally stream-lined body is now much more compact, which
literally scrunches the organs. This arrangement predisposes to food
impactions, which in turn clog up the pneumocystic duct. And causes
unbalanced body to bladder ratio. 3.Diet. Feeding dry foods which tend
to take on water like a sponge and expanded food can run the chance of
impaction. So, now we know what causes it. How to fix the problem.
Check your water chemistry. Make sure that ammonia, nitrite, and
Nitrates are at zero (or close as possible (especially the nitrAtes).
Keep the water clean and do regular water changes. Add a airstone to
makes sure the water is oxygenated properly. The next magic trick to
try is feeding your goldfish peas! Just feed your fish a couple of
store bought peas. Just get some frozen peas, thaw them, and feed them
to your fish. Not only is it good and healthy, but veterinarians thick
that the peas also help break up food impactions. Which will help
regain the buoyancy. Hopefully that will offer some help, keep the
water clean, and make sure the other fish don't start harassing the
sick one. They will pick at the fish and nip the fins. Good luck and if
you need more help might I suggest www.goldfishinfo.com. Hope the
goldie gets better. -Magnus>
Another Bloaty Goldfish - 10/30/2004 Hi <Hi, Julie!
Sabrina here, this afternoon> I have a calico fan tail gold fish,
about 3 mo.s ago he started floating upside down a lot. He can swim
right side up but only for a little while. <More than likely this is
a very simple dietary issue, but may possibly be the result of
damage/disease of the swim bladder.... My bet is on the former, as a
swim bladder issue won't usually cause the fish to float
*upside-down*. What are you feeding him?> He has all of his fins and
there is no ick in the tank. <Good, and good. How large is the tank?
Any tankmates? Are you testing ammonia, nitrite, and nitrate? What are
the results of those tests?> I don't know what to do to help him
stay right side up. If you have any ideas or answers PLEASE pass it on
to me. <Glad to do so. "Fancy" goldfish (fantails,
Orandas, etc., etc.) have pretty deformed innards from having been so
selectively bred for so very long; these genetic issues are not
curable. The result of this is that too much of the wrong kinds of food
will very easily make them constipated - Bloaty, floaty goldfish. The
very best thing you can do for this is to stop feeding him flaked and
pelletted foods exclusively, and instead use those items as a much
smaller part of his diet. For now, offer him some thawed frozen pea
(squeeze the shell off of the pea), put a few stems of
Anacharis/elodea/egeria (a water plant, available at most fish stores)
in his tank (he'll happily graze on these). You can blanch veggies
(drop into boiling water for a few seconds) like cucumber, zucchini,
squash, romaine lettuce, spinach, and more to give to him as regular
foods, too - he'll love these. I remember my goldfish when I was a
kid - they were always rescuing me from my asparagus at dinner time! If
you offer canned veggies, make sure there are no "weird"
ingredients on the label, and rinse them thoroughly before offering
them to the fish. Also, it is very easy to overfeed goldfish, so be
careful only to feed him every other day or so; even just a few times a
week, if he has some plants in the tank to munch on. Keep doing this,
and he should soon make a recovery, provided the tank is a good size,
and his water quality is good!> Thank you very much. <Any
time.> Juile Casman <Good luck with him, Juile! Wishing you and
your Bloaty pal well, -Sabrina>
Orandas with impaired equilibrium Dear Mr. Fenner,
<Kim> I have had 2 Orandas in a 55 gallon aquarium by themselves
for the past 2 years. All has been great with water changes weekly and
all ammonia , pH , nitrate levels correct. About one month ago my one
large Oranda started swimming upside down and had trouble righting
herself. She now stays at the top of the tank upside down. My second
Oranda about 2 weeks ago almost stopped eating entirely and has lost a
lot of weight. I have tried an all vegetable diet, peas, green beans,
etc. but to no avail there has been no improvement with either one of
them. I have tried the over the counter medications from the LFS for
swim bladder disease but this has not helped either. <They almost
never do> I have also tried the Epsom salts in the tank. Is there
anything else I can do? I do not want to lose them and I really need
help. Thanks, Kim <This condition is truly a heartbreaker... and
all-too-common in "roundish" breeds of goldfishes... The best
one can do is to prevent such by good maintenance and avoidance of
exclusively dried food diets... once the condition occurs, placing the
affected specimens in shallow water (still filtered...) adding Epsom
Salt, waiting and keeping trying foods is about all one can do as far
as I'm aware. Once the fish/s loose enough body fat, they often do
right themselves. Bob Fenner>
Bloated Goldie I am desperate. My 5 year old 9 inch goldfish Wiggles
is very bloated and has not eaten for about two weeks. I just don't know what is
the best thing to do for him. He has always been very active and we feed him
goldfish flakes. He has been like this before but never this long. I am really
getting worried. I read where one guy fed his fish peas and I've also heard
about putting Epsom salt in the tank. We occasionally give wiggles small pieces
of bread. Is this all right or could this be part of his problem? Please tell me
what to do for wiggles, I am desperate. Peggy <Well if he's not eating the peas
will not help. If you can get him to take one or two, go for it. Try the Epsom
salt at one heaping tbls per 10 gallons. Also, do several large water changes,
replacing the salt with each at the same concentration. If this does not help we
may have to medicate. Meds are always more effective in pristine water. They
will also cause the water to no longer be pristine, so we do that last. I would
not feed bread. Sinking pellets and veggies are ideal goldfish foods. Don>
