7 year old Oscar - forgot this!!! &
bacterial dis. f' 10/4/08
The part where the fins connect to his body (the end of the fins - but closest
to the body) is actually really red. And there are white pimple looking things
that have come & gone through this whole thing. Some big, some small, sometimes
some, sometimes more.
PLEASE PLEASE PLEASE help me save my fish!!!! No one knows what to do!!!
Thank you!
Jill
<Jill, it's difficult to be 100% sure, but this sounds a lot like Finrot or some
related bacterial infection such as Mouth Fungus (Columnaris). These cause clots
to develop on the fins, and as the tissue dies, you see red and then white
patches as tissue inflames and then dies. Often the fins become ragged as well,
with the fin membrane retreating from the distal end of the fin, leaving behind
the bony rays. A photo would help. In any case, for now, do two things. Firstly,
treat with a suitable antibacterial or antibiotic medication; in the US, Maracyn
seems to be the drug of choice for this. Make sure you remove carbon while
treating (if you use carbon) and do take care to follow the instructions
correctly. Secondly, review water chemistry and quality: cichlids are very
sensitive to poor conditions, and react negatively to them quite speedily. In
particular, ensure that the pH is stable (Oscars don't much care what the pH is,
but do insist that the pH is stable) and also review water quality, obviously
making sure ammonia/nitrite are zero but also checking nitrate is comparatively
low (ideally < 20 mg/l). Just to be sure, also check the temperature; cichlids
get sick very quickly if exposed to chilly conditions. Cheers, Neale.>

Thank you for your response but please read part one to better understand! I
will copy & paste it incase you can't readily find it! Thank you!!! :) Please
help me save my fish!!!!
<OK!>
I am at my wits end!!! I have had an albino Oscar named Oscy for 7 years. He
started out in a 55 gallon and was moved 3.5 years ago to a 120 gallon. He is
about 16+ inches and is in there by himself. He shared the 55 with a Plec but he
didn't make it to the new tank. :(
He has two power filters - an Aquaclear 500 & a Tetra Whisper 3. The water was
checked by the local aquarium store & is perfect. A few months ago, one of his
fins became very red along the "veins" and two of the "veins" were puffed up. He
still ate & behaved normally.
<Classic Finrot symptom. The "veins" you refer to are presumably the fin rays,
the bony supports that hold open the membrane.>
For years (definitely the 3.5 since he's been in the 120 gallon) he's been
eating 10 tetra cichlid sticks with 6 drops of VitaChem at about 7AM. He had
gotten hole in the head years back when the power was out from hurricanes and
the vitamins cured it - also taking out the carbon (I never put carbon in again)
- & he never had a problem with that again. He would
always come to the top at about the same time to eat.
<OK.>
The fin started looking better in Aug, & so I did nothing. In Sept however, he
stopped eating and stayed at the bottom. I went to the store & the owner told me
to try Melafix.
<Useless.>
I put the Melafix in for 7 days as per the directions and then changed the
water. His fin was getting noticeably better and he was swimming around more
normally but still not eating.
<No surprise; Melafix is at best a preventative with value in reducing the
likelihood of infections following, for example, shipping. But it is far too
inconsistent to be useful once a fish gets sick. You really need to use
something that has been medically tested across a range of situations and
species. Maracyn is popular in the US, here in the UK I happen to favour eSHa
2000.>
I still put 5 sticks with vitamins in almost everyday and he must nibble because
he couldn't have survived this long without food!!!
<Do, please, review environmental conditions. Finrot comes from two main
sources: physical damage (e.g., clumsy netting) or poor water quality. What
happens is the mucus layer on the fish is diminished and the immune response of
the fish is weakened. Bacteria that otherwise do no harm can now enter the fish
and cause inflammation and ultimately tissue death. Left untreated there is a
very real risk of Septicaemia.>
I then did a water change - I normally do a water change of a third to a half
once a week and sometimes more frequently. (4 or 5 days) I then did a second
treatment of the Melafix. His fins look basically 100%, but he seemed sluggish
again after the second treatment. Still not eating but I continue to put food
in.
<As I say, Melafix is useless here.>
I waited a week or so to let him recuperate, but even though his fins look ok,
he is more & more sluggish, just sitting at the bottom. I put a dose of Clout
in.
<Why? Clout is a treatment for a subset of parasites. Not the problem here, is
it? Do resist blindly adding random medications -- how scary would it be if your
doctor did this!>
For a while he seemed to be swimming more normally! But now he seems like he's
not able to swim very well at all. And the whole time since he started not
eating he seemed to be breathing heavy at times.
<Treat. NOW!!!>
It's gotten to the point where he looks fine - maybe a little red near the edge
of the fins near the body? - fins look normal, but he just sits at the bottom.
Doesn't eat. Breathes heavy. Spurts of seeming like he's ok, then... And the
recent addition of seeming like it's hard for him to swim. He has his bottom
fins clamped while he's sitting there - but that might be normal? They're
resting on the gravel.
<Not good.>
I love this fish but have absolutely no idea what to do. I only hope he's not
suffering.
<He is; it's the fish equivalent of gangrene. Not nice, so run to the pet store
and get some Maracyn (or whatever).>
Please help!!! If you need any more info please ask. I really don't know what to
do!!!
Thank you!!!!
Jill
<Cheers, Neale.>
Re: 7 year old Oscar - forgot this!!! –
09/04/08
Thank you for trying to help me - no one else seems to be able to or care!!!
<Oh? Well, glad we can help.>
I put the Clout because it listed being for symptoms of heavy breathing, lying
on the bottom... And the guy in the fish store said they use that.
<Pshaw...>
The thing that makes me confused into not thinking it's fin rot is because his
fins look fine! The redness & swelling are totally gone!
<Well, that's a good thing.>
What he has is the redness at the end of the fins near the body. And he breathes
kinda heavy & doesn't swim much. And when he does it seems difficult.
<Bacterial infections weaken the fish, and eventually the bacteria get into the
body itself, not just the skin, causing serious harm, potentially organ failure
and death.>
And he doesn't eat - though like I said I assume he must...?
<Oscars can go weeks without food. Not an issue. Concentrate on treating the
disease. Once healthy, he will eat again.>
And the water has always been tested & good quality.
<Meaning what...? Please, give us numbers: pH, nitrite, nitrate at minimum.>
And the only damage he could've had is from digging holes in the gravel.
<Nope.>
So I don't see how it's fin rot.
<Well, without a photo can't be 100% sure, but it is by far the most common
reason fish get "red fins".>
But as soon as the store opens I will get Maracyn.
<Good.>
I hope this works!!!
<So do I.>
I will keep you posted and if you have any other ideas please tell me!
Thank you!!!!!!!!!!!!!!!!!!!!!!!!
Oh! One more thing! With the second treatment of Melafix they told me to put in
aquarium salt. They told me to do half the dose. Is this useless too?
<Yes.>
I can't find much on Septicemia - but this* is what I found on fishforums.net
He has no sores but the rest sounds close...
????
Should I get Oxytetracycline Hydrochloride Powder? I don't even know what it is?
<No.>
Should I try the Maracyn first?
<Yes.>
*Septicemia: A fairly rare to common in all tropical and coldwater fish. It is
caused by bad tank conditions and is very hard to cure if not impossible.
Bacterial Hemorrhagic Septicemia can be diagnosed by red streaking of the fins
and body and once this disease progresses, ulcerations and body sores start to
appear. There is significant loss of appetite, lethargy, loss of motor functions
in the later stages of the disease.
Treatment: I recommend using Oxytetracycline Hydrochloride Powder obtained from
a vet to cure this disease.
<Septicaemia is simply a bacterial infection of the blood. Nothing more, nothing
less. It's what in humans is often called "blood poisoning". The classic
situation is where an external wound or burn becomes infected with opportunistic
bacteria, i.e., Finrot, and these are able to breech the fish's natural defences
and travel around its body via the blood. With fish at least, septicaemia is
very difficult to treat reliably, which is why treating external bacterial
infections promptly is so critical. Messing about with salt, Melafix and other
half-baked solutions may be cheap and appealing, but because they don't work
reliably (if at all) all you're doing is swapping an easy to treat infection
like Finrot for a difficult/impossible to cure case of septicaemia. Cheers,
Neale.>
Re: 7 year old Oscar - forgot this!!!
10/8/08
Hi there! I put the Maracyn 2 in. He is moving around a bit more but still
mostly sitting on the bottom & breathing kinda heavy. He seems to not be able to
swim very easily when he does get a burst of energy to move.
<If the bacterial infection is severe, it will take time for him to get better.>
I have 2 more doses to put in. I am wondering what to do next!!!
Do I change the water & do another 5 day treatment?
<Yes; at the end of each course, I'd do at least 25% water change, even 50% if
you are able to keep water chemistry relatively stable. Then start a new course
of treatment.>
Do I try something else?
<Nope.>
Do I wait?
For how long?
<Impossible to know. May well take a month or more for him to get to full
health.>
Please help!!!
The fins look fine, and even the redness on the edges near the body are getting
less red.
<Good sign.>
Will he get better?
<Hope so!>
Does it just take time?
<As does everything in life.>
I'm very worried & want him to get better!
Thank you for your help & advice!!! :)
<Good luck, Neale.>
Re: 7 year old Oscar - forgot this!!!
10/8/08
Ok just to make sure - the last dose is Thurs. So do a water change Fri & then
put the next dose right in?
<Yep!>
Thank you sooooooo much btw!!!! I don't know who you are but I hope everything
good comes to you!!! :D
<That's very kind! Good luck to you and your fish, Neale.>
Re: 7 year old Oscar - forgot this!!!
– 10/10/08
One more question - sorry! :o
The very first dose of
Maracyn 2 is double what you put for the next 4 doses.
So since this is the
second treatment, should I just do the single dose for 5 days or start fresh
with the double dose? (That's the one I was assuming...?)
<With antibiotics,
you MUST always do precisely what the prescription or instructions say; unless
you're an MD or a vet (and I'm neither) coming up with your own doses is a very
bad idea, and how things like antibiotic resistance get bred into bacteria.>
And then how long should I continue this? I mean, once I give a second treatment
for 5 days, do I keep on until he's totally 100% better or is there a point
where that's enough/too much meds?!
<You can stop after the second set of
treatments, wait a couple weeks, and see if things are improving or not.>
Like what's the maximum number of 5 day treatments I should do? (& should it
always be the double dose for the first of the 5 days?)
<I do not know the
maximum number of doses. Antibiotics are not available over the counter here in
the UK and I have no experience of using them with fish. Consult with a vet or
the manufacturer; I suspect any answers from non-medically trained fishkeepers
will be nothing more than guesses.>
Hopefully he'll be well after this second
treatment :D but in case not...
I suppose I can judge his wellness by when he
actually starts swimming to the top to eat again! I put 5 tetra cichlid sticks
with the vitamins in every day & it floats to the bottom.
He must be eating
it cause he would've starved by now! He used to eat 10 of those every morning -
always swimming to the top to get them...
Thank you!!! :)
<You're welcome,
Neale.>
Re: 7 year old Oscar - forgot this!!!
8/18/08
I was just reading on your sire & it hit me that I forgot to
mention eating & "going"...
<Going where...? For a walk? To the post
office...?>
I never see him eat - but I put sticks with vitamins in everyday
& assume he has to be eating, though when I change the water there's a lot
there... I just assume he must be eating some!
<Mostly Oscars are overfed.
Anyway, they like variety, and tend to become "hooked" on one brand or type of
food if used too often. Alternate between sticks one day, mussels the next,
snails the next, unshelled shrimp after that, and so on.>
Have no idea if
he's "going or not...
I was also reading about Epsom salt. Should I try this?
<Does your fish look constipated? If your fish has a clean anus and a gently
rounded by not swollen belly, then constipation is unlikely a key issue. If a
fish is sick, it shouldn't be fed much if at all. Oscars can go a long time
without food. Offer him something tasty like an earthworm every few days. If
he's up for that, then try one or two more that day, but then let him fast for
another 2-3 days afterwards.>
I don't know what to do for the poor thing!!!
<Indeed.>
I don't want him to die - and most of all I don't want him to
suffer!!!!!!
<Agreed.>
He's moved a bit around the tank but still lying on
his side...
His body looks fine, fins are better...
<Good.>
One other
thing is that once in a while it'll look like he's "burping"...?
<Well,
obviously fish don't burp. But they sometimes seem to "cough" when masticating
food as they move it around their front jaws and the pharyngeal teeth in their
throats. In itself nothing to worry about.>
There is some medicine I've seen
mentioned that starts with an M...
<Not Melafix, I hope. It's rubbish.>
And Methylene Blue I know of.
Should I add salt?
<Why? It's not a brackish
water fish.>
Medicate more?
<I'd perhaps do a nice big water change (say,
25-50%) and not treat for a week. See how things progress. Do take care water
quality is good and there's lots of circulation.>
What do I do????
:(
Thank you for your help!!!
Maybe you can ask the others there to see if they
have heard of this either?
So many different people say so many different
things!
I'm trying to find a fish dry with not much luck...
I found two
places I'm going to try to call - not sure if I can get them on the weekend...
<Cheers, Neale.>
Re: 7 year old Oscar - forgot this!!!
8/18/08
Hi there! I really need some more advice - the last dose was
Thurs. I changed the water Fri. All day Fri & Sat (today) he was in the corner
(which isn't unusual - they pick their spots in the tank :) - but he was leaning
to one side - his left, which is the side his fin was bad on.
<I shouldn't
read too much into which side he was leaning on.>
Now Oscars do lean to the
side like that, but he just stayed like that. Well now he's out in front, but
still leaning that way. He's not breathing really heavy, maybe a bit more than
normal - can't really tell.
<Do check the filter, and perhaps add additional
aeration.>
It's just the leaning to that side. He's not like lying down, just
tilted that way. What does this mean?
<Without a photo, impossible to say. He
may be weak or just plain tired. Does he look swollen or constipated? If he
does, then treating with Epsom Salt might help. Otherwise I'd review water
quality and water chemistry just to make sure everything was fine, and then let
things be. If he's getting better -- and it sounds as if he is -- then best to
keep doing what you're doing and let him heal.>
I don't know what to do!!!
It seems there's nothing I CAN do... Is there?
<Remember, much medicine comes
down to nixing the source of the disease and then giving time for the body to
heal itself. There's no magic alternative to "time the great healer" for either
fish or humans.
Please advise!
Thank you!!!
<Cheers, Neale.>
Re: 7 year old Oscar - forgot
this!!! 10/19/08
Ok - still leaning, but
now he has a small bubble (looks like the kind you blow with gum or the
kids stuff with the wand) coming out of his anus. It's small - about the
size of your pinky nail area. But I just saw this today. Maybe that is
from gas since I did notice that "burping" motion? What is that? What
can I do???
Please help!!!
<Could be a slight prolapse, which can
be improved with time and Epsom salt treatment. It's really difficult to
make a diagnosis without a photo. Would heartily recommend getting a
sharp photo (not too big, <500 kb). Failing that, take the fish to a
vet. Cheers, Neale.>
I FORGOT THIS!!! Re: 7 year
old Oscar - forgot this!!!
I forgot to mention that he's
almost completely on his side now & his breathing is slow!
<Well this
isn't good.>
If he is on his way, what can I do to make it easier for
him?
<On his way where? Dying? In that case do see here:
http://www.wetwebmedia.com/euthanasia.htm
>
How long would it
take?
Is there anything I can do to try to save him???
<If
all else fails: the vet! There's only so much I can do without a photo.>
Help!!!
:( :( :(
<Cheers, Neale.>

PICTURES!!! Re: I FORGOT
THIS!!! Re: 7 year old Oscar - forgot this!!!
<Right. The
anus is prolapsed, and all else being equal this can be undone over
time. But the fish is quite clearly very, very sick. The eyes are
popping out, and if both eyes are like this, it's a pretty good sign of
a systemic bacterial infection. Almost always this follows on from
chronic water quality/water chemistry issues. The colour is very pale,
and I'm assuming this is some sort of albino. That being the case,
albino fish are invariably weaker than the regular sort, and that gives
you little margin of error. My gut feeling is that euthanasia is the
only option here. Otherwise this fish will need to see a vet, stat.
There's nothing over the counter I can think of that will take this fish
back to good health if it's half dead already. Cheers, Neale.>
Re: PICTURES!!! Re: I
FORGOT THIS!!! Re: 7 year old Oscar - forgot this!!!
His
eyes aren't popping out...?
<Look up "exophthalmia" in your fish
health book, or in Google images.>
He is an albino.
<Yep.>
You
said this prolapse (?) can be reversed - HOW???
<Time, good water
quality, basically solid health. Epsom salt treatment will help. Use the
WWM search tool for this.>
There are no fish vets.
<Sure there
are.>
There is a pond dr - he basically said if the fish isn't eating
then there's nothing I can do.
<Not true, but certainly once fish
reach the point that they're not eating anymore it's often hard to pull
them back.>
I don't know if he's eaten or not.
<Well, assume not,
and don't worry about it. Starvation isn't what's killing this fish.>
But maybe if I can reverse that thing he will get better.
<A prolapse
is a symptom of a bacterial infection of the gut. When the bacteria go,
the prolapse usually reverse. It's a symptom, not a disease, so don't
focus on it too much. It's like when someone has a runny nose, it's the
cold virus that's making them sick, not the mucous. Metronidazole can
help deal with whatever is irritating the intestine. Again, the search
tool will help you review previous comments on WWM re: Metronidazole and
prolapses. Cheers, Neale.>
HELP!!! Re: PICTURES!!! Re: I
FORGOT THIS!!! Re: 7 year old Oscar - forgot this!!!
He's
now standing up...
<Well, that's good, it by "standing up" you mean
he's swimming normally.>
What does this mean?
What do I do?
<Keep up whatever you're doing. Sorry there's no silver bullet here.
Time, use of antibiotics and perhaps Metronidazole and Epsom salts may
provide some assistance. Cheers, Neale.>
Re: HELP!!! Re: PICTURES!!! Re:
I FORGOT THIS!!! Re: 7 year old Oscar - forgot this!!!
He's gone.
Thank you for all your help! We tried. At least he's not suffering.
<Sorry for your loss. As always, try to temper the situation by learning
from it: review water chemistry, water quality, diet and other issues
before you think about buying a replacement. Oscars are lovely "pets",
but the more inbred forms such as albinos and veil-tails are much less
robust than the standard Oscar, so you might want to think about this
issue as well. Cheers, Neale.>
Re: 7 year old Oscar - forgot
this!!!
There are no fish vets here!!!!
You keep saying that! There's no such thing!!!
<I admit not all vets will treat fish. But some do, and with a bit of
telephoning around, or asking your local retailer, you should be able to
find one locally. Treating fish generally isn't expensive, as the vet
will often prescribe stuff you can use at home. Here in the UK there is
a division of the British Veterinary Association that maintains a
network of vets who treat fish. I'd imagine many other countries have
similar organisations.
http://www.fishvetsociety.org.uk/
>
And you can't bring a 16+ inch fish to a vet anyway!!!
<Yes you can. People take Koi carp to vets, and they're MUCH bigger than
Oscars. The "trick" is to use a really big container, like a 5-gallon
bucket or a plastic picnic cooler.>
Do they actually have fish vets where you are???
<Yes.>
The only thing they have here is pond Dr.s - they're extremely expensive
- they only deal with Koi that are thousands of dollars!
<Koi are indeed expensive, and that's why people are willing to spend
money treating them. With aquarium fish prevention is invariably better
than cure, which is why, with things like Oscars, you'll understand why
we recommend big tanks, generous filtration, regular water changes, and
proper food. Live foods such as feeder fish shouldn't be used because of
the major risk of introducing disease. I always stress my preference for
"wild type" fish over inbred albinos and the like because the less
inbred the fish is, the less likely it is to get sick. Things some
breeders find "pretty", such as albinism, rarely go along with
improvements in vigour!>
How do I do the Epsom salt treatment?
<Described elsewhere on WWM; use the Search tool.>
Thanks!
<Cheers, Neale.>
PLEASE HELP!!! Re: 7
year old Oscar - forgot this!!!
I tested the water - it's fine.
He's lying more to his side.
He once in a while looks like he's burping.
The breathing seems normal - maybe a little rapid - can't tell.
I don't know what to do for him!!!
Please help!!!
Thank you!!

Injured Oscar Fish: How to help it
10/1/08
Dear sir or madam,
<Emma>
I'm writing to ask for your help with my tiger Oscar cichlid fish.
My fish is currently in a 55 gallon tank.
Two days ago it had a blood parrot cichlid for a tankmate.
The two fish got into a fight while I was at work.
<Yikes!>
Each fish was de-scaled by the other (don't know if that's the right term for
it).
Basically the top layer of scales in a small area on the Oscar's left side is
gone, and I can kind of see the flesh underneath.
The parrot was also beat up badly. I removed it to a 40 gallon.
<Good>
The Oscar, now by itself in a 55, is now refusing to eat.
<Not a worry... will do so in time>
It doesn't swim around like it use to; just sits at the bottom of the tank
motionlessly.
<"sulking">
Sometimes when I check in on it, I think its dead. I'm really scared. I love my
Oscar.
I keep the water in perfect condition, so water quality is not a problem.
I want to ask you if this behavior was normal for a recuperating Oscar?
<Very much so, yes>
I'm not familiar with fish behavior during times like this, so I'm really
worried.
Is it lethargic because it's in the process of healing from the wound?
<And psychologically, yes>
Or is it suffering from some disease I might not know about?
<Not likely>
Can a wound like that lead to any diseases or infection?
<Possibly>
Please help me with this. I just want to help it get better.
What can I do to help it?
-Emma
<Read: http://wetwebmedia.com/FWSubWebIndex/oscardisfaqs.htm

Red Hairs coming out of my Oscar's anus, reading 08/28/08
Hello,
<Hi there>
I've read through your site (awesome by the way) and found similar problems as
my Oscar, but not exactly. I have a 3" tiger Oscar for 3 weeks now (first time
owner), and he has developed a swollen anus with little red hairs coming out of
it. What is this?
<Likely Camallanus>
What can I do about?
Should I be worried? Please help him!
Thanks,

Sick Oscar - need help ASAP please, env., reading re HLLE 8/26/08
Hello,
<Eddie>
I have had this Oscar fish for over 2 years. He lives in a 60g
<Needs more room than this>
aquarium along with 3 parrot fish, Gourami, Knifefish and a Pleco.
Ever since he developed the hole in the head disease (1.5 years ago),
I've been changing 50% of the water in this tank biweekly.
<... this won't cure this>
He eats dry pellets (3 different types) and blood worms. The development
of the HITH disease stopped as soon as I started changing the water on a
biweekly basis. However, 4 days ago I noticed that my fish started developing
another "hole" but this time it was surrounded by what looked like a bruise.
Today, I saw a white film coming off the spot of the new hole (please see
attached photos). I've also started feeding it with frozen dry krill 2 days ago,
hoping that it might help. I have already made 2 50% water changes in the past
week and have another one scheduled for tonight. Otherwise, he still eats and
swims OK. There are no signs of parasites or visible bacteria nor there are
signs of blood.
Please let me know what you think that it can possible be.
Any help will be greatly appreciated by both me and my Oscar fish.
Thank you,
Eddie

Re: Sick Oscar - need help ASAP please
8/26/08
Thank you Bob for your prompt reply. I will certainly read the HLLE FAQ and I've
been looking into getting a bigger system. Based on the pictures, do you think
that I have another case of HLLE in him at the moment?
<Mmm, not able to discern... looks more like a mechanical injury/trauma to me>
This "injury" doesn't quite look like a hole in the head.
Also, the white spot he had on his back seemed to disappear after a few water
changes and two days of Krill and bloodworms diet.
Right now I change 25% of the water once a day and hoping that the fish can
recover on its own without an addition of any medications. (for the next week or
so)

Oscar Gill Sticking Out
8/11/08
Hi we have an Oscar fish for almost a year and we just changed him to a new
55 gallon tank. My question and concern is that if looking at him
his left gill seems to be coming out further than his right when
breathing. He also seems to be opening his mouth more when he takes
a breath. I'm not sure why one gill is pushed out further than the
other, our other fish/ Oscars are fine. Please help!!! Thank you.
< I think what you mean is that the one gill cover doesn't
completely close and maybe stays out a little more than the other
one. There could be a growth or something within the gill that is
preventing it from closing the whole way. I would remove the fish
and restrain him with a wet towel from the aquarium and hold him
down and gently pry back the suspect gill cover and look quickly
with a flashlight to see if anything was in the way. Without
actually seeing anything then I might suspect gill flukes and treat
with Fluke-Tabs. Flukes could have come in with feeder fish.-Chuck>
Re: Oscar fish
Oscar With Stuck Gill II 8/11/08
Thank you so much for your reply. The Oscar fish seems to be healthy
except for the fact that his left gill doesn't open at all. The weird thing
is that both gills work fine while he eats. He seems to be eating as much as
usual, but his breathing is a bit irregular and a bit faster than usual. Do
you think that taking Oscar out of the tank and putting him on a towel to
inspect his non-working gill won't traumatizing him in some way?
< It is going to be your call. You are correct that this will stress you
Oscar in some way, but not moving water through this gill is like you trying
to breath with one lung. The only way to find out what is going on is to
inspect the area. If he gets worse then it will become more stressful later
on.>
We have already lost three of our oldest fish (when we did the switch to the
new 55 gal tank) and we would really hate to do anything that might put his
life in any kind of danger. The water is in optimal condition, their diet
doesn't include any live fish, and the temp is an even 78°. We do a tank
clean-up once a month which includes a filter and a 5 gal water change (we
only use drinking water since our tap water is way to hard). Please advise,
thanks again for all your help!
Santi & Sky
< Hard to believe that with a 5 gallon water change you don't have higher
nitrates. Another potential problem may be some ammonia burn when the new
tank was changes over. This is caused by an ammonia spike and it actually
eats away or burns some of the gill filaments. These may heal over
time.-Chuck>
Re: Oscar fish
Changing Water In An Oscar Tank 8/13/08
Are you saying that is NOT good to change 5 gals out of 55 gals every month
while cleaning the bottom gravel? Even though it's drinking water? Are you
saying that it has to be a bigger qty. of water that needs to be changed? Could
you please explain that to us, we keep getting different stories from different
people :(Thanks again!
< Oscars are big messy eaters. You are probably changing less than 10% of the
water. It is hard to believe that your nitrates are not a problem. Usually I
recommend at least a 25% weekly water change for such large fish, but you say
the water chemistry is fine. As long as the fish are doing ok then that is all
that really matters.-Chuck>

Very Sick Oscars 7/9/08
Hi,
<Hello!>
I've read over some of the questions and answers on your site, but I'm still
not positive I've found enough of an answer, so hopefully you can help me. I
have two Oscars that are about three years old and have never had problems
other than a few incidents of HITH which cleared up in a few days. About two
days ago I found one of the Oscars laying on his side on the bottom of the
tank with what looked like a large bubble around his anus. The other Oscar
seemed fine for a few hours, but then she began swimming face down into the
bottom of the tank and just stayed there. She's since been laying on her
side on the bottom of the tank with the male Oscar. Thanks to your site, I
added some Epsom salt to the water and it seems to have helped. The bubble
on the male deflated, but partially came back the next day, but has since
disappeared.
<Well, that sounds promising at least.>
I changed the water completely and washed out the tank and filter with hot
water. I removed the gravel and ornamental rocks in case they were housing
any diseases/bacteria. Water tests only showed a spike in ammonia from 0 to
1.0 which I'm still treating for, and pH is at 7.0. Nitrate and Nitrite
tests show a slight spike as well, and I'm also
treating for this. I've removed the two Plecos that share the tank with the
Oscars so I can treat the Oscars for various diseases. Over the course of
two days, the female has developed swollen gills, but no other visible signs
of illness. The male's fins have begun rotting and eyes have become cloudy.
I've started the Oscars on Maracyn Two along with the Epsom salt.
<Does sound as if these fish are suffering from a range of general
illnesses. Do review water chemistry and quality. Ammonia at 1.0 is
obviously lethal to most fish, but cichlids are especially intolerant of all
the nitrogenous wastes, ammonia, nitrite, and nitrate. Tanks with Oscars and
Plecs demand major filtration, so adding another substantial external filter
could help in the long term and will certainly do no harm. Big fish also
cause pH to fluctuate, a point often overlooked. Review the carbonate
hardness of the water and act accordingly. In tanks with big, messy fish
there's a good argument for artificially raising the carbonate hardness to
at least 5 degrees KH simply because this will neutralise background
acidification between water changes.>
I've never used feeder fish, but have given them an occasional raw,
unshelled shrimp. They usually eat Cichlid pellets, peas, and rarely some
fruit.
<All sounds fine. The golden rule with raw foods is that marine organisms
are safest for freshwater fish because there aren't any parasites that are
likely to come from the sea but could infect freshwater fish. So raw shrimp,
mussels, lancefish, etc are safe.>
Since they've been sick they haven't been eating much. I have to push the
peas in front of their mouths, which they rarely take. They try to become
active when they see me near the tank, or when I turn the tank light on.
I've also added some freshwater salt, and Stress Coat, to help with their
breathing, stress, and healing. I'm wondering if you think this could be a
bacterial infection that has affected their swim bladder since there are no
visible signs (other than the fin rot which has only recently developed) for
why they are not able to swim around?
<More likely simply a systemic "under the weather" reaction to something
environmental, even poisoning, e.g., paint fumes. Do review and act
accordingly. Treating for internal bacterial infections (e.g., with Maracyn)
is not a bad idea at all. But optimising water quality will be essential.>
And I was also wondering if you know of anything else I can do to help them?
I know they're tough fish, so I'd hate to give up on them before it's too
soon. Thanks in advance for any help you can provide,
Brittany.
<Not much more I can say without a photo! Do hope this has helped, and I
suspect you are doing all the right things anyway. Some info on the size of
the tank, filter used, carbonate hardness and water temperature would all be
useful. Cheers, Neale.>
Oscar with skin problem
– 06/29/08
Hi Bob, I was looking at your website for the first time today.
I bumped into it when looking for information about Oscar Diseases.
Congratulations, you are a great resource for the non-sabbi aquarium
people like me. I've had fish tanks since I can remember, and I love
it. I have a 4 year old Oscar, it has always been very healthy. I've
never had any problems until last week when my fish just stopped
eating. I tried feeding him but he doesn't seem interested in
eating, everything else is normal, he seems to be in an excellent
form, except he has a skin problem. Now his skin is peeling off and
I don't see signs of any other problems just the peeling off, and
that's it. He doesn't go to the bottom of the tank or any other
weird behavior. Though, it has a big chunk of skin and flesh exposed
on the side of his head, but it seems it's all caused by the same
thing, there are no other major problems with it. I'm including a
picture. Can you tell me what's wrong with my Oscar?
<Good graphics... do you feed this fish, tank live freshwater
foods?>
I couldn't find anywhere information about these symptoms on his
skin. I read in your website a comment
(http://www.wetwebmedia.com/FWSubWebIndex/oscardisfaqs.htm) by
somebody who seems to have the same problem, and his local expert
says it might be a nutritional problem, am I dealing with the same
kind of problem here, or is it something else? Can you tell by
looking at the picture? Thanks, any kind of help will be greatly
appreciated. Cesar O.
<I can't tell with any great confidence... W/o any further input
than the photos I would guess this was a physical complaint... a
mechanical injury... Could be microbial... Again, please send info.
along re water quality tests, maint. procedures, foods/feeding.
Cheers, Bob Fenner>
Re: possibly dumb explanation for
the sick Astronotus - 06/29/08
Hi Bob, Looking at those photos got me in mind of a goby I kept
that was attacked by Otocinclus sp. catfish. I hadn't thought this
was a problem with something as fast-moving as Awaous sp. gobies.
Anyway, I was puzzled why this goby was developing a rash on its
flanks. Finrot remedy didn't help. Eventually I caught the
Otocinclus in the act, grazing away at the mucous and damaging the
dermis. Is it possible that this Oscar is cohabiting with a Plec or
similar that has developed this habit?
Cheers, Neale
<Is indeed a possibility. Will accumulate your input here, send on.

Oscar Issues hlth. - 06/08/2007
Hi,
One of my Oscars has recurrent white circles that come and go, mainly on
his head. They typically clear up with water changes, but this time
nothing has helped. The tank is a 115 gallon.
Today I added a little aquarium salt and have made the water more
alkaline, but it's too soon to know if it will help. The pic I've
included is a little large, but it's hard to photograph the circles. I'm
guessing it's a fungus and maybe this Oscar has a poor immune system
because all the other fish in the aquarium seem to be fine. He has had a
deformed head since birth, but he's about 10" now and hasn't had any
other problems.
I am reluctant to medicate because I don't want to compromise the
biological filter. Any suggestions?
Thanks,
Steve
<Steve, although I'm not 100% sure (the photo is a bit blurry) my
immediate feeling is that these are bite marks. Since you have more than
one Oscar in the tank, it's likely they're fighting. Bit marks typically
consist not of a single ring, but rather a pattern of tiny scratches
(the teeth marks) arranged in a circle. If no serious harm is done, you
may as well leave them to it. Medication shouldn't harm the biological
filter if used as directed on the packaging. In this case, an
anti-Finrot remedy might be in order, just to make sure nothing serious
developed. Salt is neither here nor there really, and won't stop a
bacterial infection though it may help against fungus. I personally
wouldn't bother with salt, and instead would use a proper antibacterial
of some kind. Given the fish is otherwise healthy, and these wounds
shouldn't have damaged the skin too badly, even something as lightweight
as Melafix might have a role. Cheers, Neale.> |

Oscar in need of help. - 05/31/08
Hello,
<Hi there>
We have a 10+ year old Oscar that is in need of assistance. My girlfriend and I
have been treating the Oscar for a bacteria infection.
<... how? With what?>
The symptoms were scales pealing off and bleeding, redness in the gills and
throat, fin rot and body slime. We have got all of these symptoms under control
using T.C. Tetracycline by API (under direction of the local fish store). He has
responded well to the medication and these symptoms have subsided. The side
affect is that the tank is now pink (all water levels are fine we have been
keeping up with this at the local pet store) Unfortunately it appears that there
is now a white cotton ball coming out of his colon and he is floating listlessly
on his side at the bottom of the tank. On your blog we have found the words
"Prolapsed Colon". When this started we were able to feed him some medicated
pellets about 2 days ago (Pond anti bacteria medicated fish food) Since then he
has lost his appetite and has not passed any food through him. It is our guess
that the food that he ate last is rotting in his stomach.
<Perhaps>
Today we have tried to feed him peas with no success due to his lack of appetite
and our limited knowledge on how to force feed a fish. Some of the questions
that cross my mind are: Is there anything that we can give him to help him pass
what is in his stomach?
<Maybe the addition of Epsom Salt...>
Is there any remedy for a prolapsed colon?
<The above and time going by really>
Or could it be fungus coming out of his colon that we need to pull out to help
extract what is in the stomach? Please send any advice that you can as soon as
you can. We will be waiting eagerly on either email address this one or the CC.
We fear he does not have that much time left.

Oscar On The Decline
5/27/2008
Hi: My son brought his 2 Oscars
home from college a year ago, where they have stayed even after he returned at
the end of the summer. When they first came home, they were both very aggressive
and were fed feeder fish. I changed their diet to Tetra Cichlid Sticks and both
fish were doing fine. They became much less aggressive. Around March we changed
their tank to a 55 gallon tank, but didn't change anything else. By the end of
April, I noticed a big difference in the female. Her skin was rough & she
eventually developed 2 perfectly round holes in front of her gills. She always
seemed to be having difficulty breathing & even her side fins looked feathery
and had rips in them. She died and now the male fish has the same symptoms. I've
been researching the internet and have asked for help at the pet store. Last
week we changed around 25% of the water and removed the carbon filters and
treated the tank with Metronidazole. He seemed better afterwards and even
started eating again (Another symptom I forgot to mention was loss of appetite).
By the end of the week, however, he's worse. He has developed a perfectly round
hold beside his mouth. He also looks like he's struggling to breath and even the
insides of his mouth look white on both sides. His side fins are ragged and
feathery. The female was white, but where he's black, I can see little white
places on his body. Even his top fin is looking white at the tips. There is a
cichlid and a catfish in the same tank that seem perfectly find. Please help or
give me some suggestions. I'm afraid he's going to die too and it's hard for me
to watch him wasting away with each passing day.
Please Help ASAP Beth
< Your Oscar sounds like it is being affected by stress and is generally
breaking down and succumbing to all kinds of diseases. First get the tank
healthy. Do a 50% water change, clean the filters and gently vacuum the gravel.
The ammonia and nitrites should be zero and the nitrates should be under 10 ppm.
Maintain these water quality parameters with water changes. Increase the water
temp to 80 F. Treat with both Nitrofuranace and Metronidazole. Treat every other
day and do 50% water changes in between treatments until his appetite comes
back.-Chuck.>
Oscar In Decline Part 2
5/27/2008
So sorry - I forgot that I
bought a testing kit and ran a test on the water. pH = 7.4; nitrate = 3.5 ppm;
nitrite = 0; ammonia = .25
I know the ammonia should be 0, but I didn't think .25 was bad.
< The medication may have wiped out the biological filtration so this could
account for the ammonia reading.>
Also, I can see little white flecks on the side of the tank near the filter, but
I read on the internet that this can be a helpful parasite that feeds on the
feces. Please help Beth
< Hard to identify little white specks as parasites. Usually parasites stay on
the fish.-Chuck>

Oscar health
issue parasite or fungus? 05/15/08
Hi Crew,
I have attached a picture of my male (confirmed) Oscar's problem area. I
don't know if this is a parasite or fungus or what! Overall he seems
very healthy, eats well, but has suffered the loss of his mate. Not sure
if that has anything to do with this.
<Likely so>
But my question is are you able to identify this? and if so can you tell
me what I need to do to get rid of this? Any help would be greatly
appreciated.
Dominique
<Mmm, the white "peg-gish" matter under this fish... could be simply
resultant from physical trauma. Do you feed live material that might
carry worm parasites? Bob Fenner> |

Re: Oscar health issue parasite or fungus? 5/17/08
Thank you so much for your response, I woke up this morning and it was
gone! I don't feed Mickey live food. I haven't added any other fish to
the tank in a year but he does have two rather large rocks in the tank
that I am going to take out. I think it is possible he could have bumped
them.
<Ah, yes>
I did however clean out his tank with a 50 percent water change the day
before it disappeared.
<Mmm, best to limit such water changes to about a quarter of the tanks
volume maximum>
I am going to keep any eye out and if I see it returning the pet store
said to bring in a water sample and a bit of what's hanging off him and
they can check it out for me. Again thank you for your response.

My Oscar hurt bad, poisoned
4/29/08
Hello,
<Hi there>
I just found your website and I'm hoping that you could help me. My
Oscar had HITH and I went to PetSmart and got some medication.
<What exactly?>
His head seems to be getting better, but he is going crazy! He's been
swimming rapidly and hit himself on the gravel, side of the tank and the
log on
the bottom of the tank. He scrapped a chunk of skin off his head, his
gill and some on his side. Last night he banged himself pretty hard that
he chipped his bottom lip. He's still eating some freeze-dried
bloodworm, but he spits out the pellets. I'm very worried about him and
I don't know what to do. He keeps hurting himself and I don't think he's
going to heal if he keeps it up. Please help, I feel so helpless with
him. Thank you.
Resy
<Something toxic going on... likely related to the Neuromast destruction
treatment. I'd quickly change about half the water (treated to remove
sanitizer...) and run some activated carbon in your filter/circulation
path. Bob Fenner>
Re: My Oscar hurt bad
4/29/08
I treated him with anti-parasite tablets twice,
<... Please... specifically... this term means nothing. What active
ingredients?>
48 hours in between treatments. I changed 25% of the water after the
second treatment and put back the carbon filter. I also put the stress
zyme and stress coat as directed in the box. Should I change 50% of the
water again?
<I would, yes. B>
Re: My Oscar
hurt bad
4/29/08
This is what's on the box: Active ingredients: Praziquantel;
N-[[(N-Chlorophenyl) amino] carbon 1]-2,6-difluorobenzamide;
Metronidazole; Acriflavine. Wont' changing the water again stress him
more? It was only two days ago.
<Better to be stressed than die from toxic reaction... Likely the
Flagyl/Metronidazole is at root here. B>
Re: My Oscar hurt bad
4/30/08
Thank you. I will change his water again. How often should I change
his water afterwards? Should I put a new carbon filter again, also?
<See WWM re water changes and yes to the chemical filtrant. B>

Oscar Fish
Hole in the Head??? 4/4/08
Good Evening
I have attached a photograph of my Oscar Fish and wondered if you could
help.
I'm not sure if my Oscar has hole in the head disease. I have studied
several photo's of Oscars with this disease however the holes in my
Oscar look much bigger and deeper. I haven't seen anything like this
before.
Are you able to advise??
Any thoughts greatly received.
Regards
Julie
<Julie, yes, that's Hole-in-the-Head disease. Options for treatment in
the UK are limited unless you contact a vet. Metronidazole is the usual
recommendation by American aquarists, but it isn't freely sold here in
the UK. One new product on the market is eSHa Hexamita Discus Disease.
Their other products are excellent, so that'd be one product I'd
recommend. Follow the instructions carefully, in particular remembering
to remove carbon. In any case, the underlying cause of HITH is water
quality and/or diet, so review those factors. Do see here:
http://www.wetwebmedia.com/FWSubWebIndex/fwhllefaqs.htm
Cheers, Neale.> |
