    I included the article on Fish Disease and Treatment. It might be Fin & Tail rot which is a bacteial infection. He could have had it when you brought him home. He could have hurt himself somehow in the tank and it caused a bacterial infection. Another fish could have nipped him. It happens. Anyway, look at the article and find the symptoms and check out that disease and just look at symptoms in general. The recomended treatment is there.

My puffer is sick.....I think! He has gone from a white belly to a gray belly back to white and back to gray. I have tested the the salinity and the ph and I think it was ok. He is not eating and there are ghost shrimp minnows and snails in the tank. His teeth don't look long.....that is if I know what I'm looking at. I think he was cold too so I warmed the water. Please help!!!!!????

    Don't panic - at least not yet. Puffer fish do change colors. They do it in their natural enviornment with some degree of regularity and they also do it in an aquarium situation but less frequently. The color change is many times due to stress - temperature change in water or condition of water or too many fish in the tank etc. Obviously, it can also be because he isn't feeling all that great. I have included an article "Fish Disease and Treatment" from Animal World. Check the tank enviornment throughly. Also, what size is your aquarium? It is recommended for 1 puffer that a 20 gallon be used and if there are other fish to go to at least a 50 gallon. Good news it is not unusual for puffers to change color, but the YUK news is that it is usually do to stress. Check the tank conditions and do the recommended treatments. Not eating is also a sign of stress.
    Read the article on the Puffer because the tank enviornment required is there. Also to be careful of amonia and nitrates as they don't necessarily eat all their food so tank gets messy. Also article says to change 30 - 50% of the water per week. Bunch of little things that can be happening here but let's just check them out one at a time. OK?

    You are crazy, warming up the water sometimes makes matters worst....
    It's normal 4 a green puffer to change colour of the belly. It's a healthy little guy, except if it stays with grey colour.....

    Well my black moor eyes are cut up and are about to fall out.:(
  • Charlie Roche - 2011-07-05
    There are several things it could be. I have cut/paste the eye problems from the Animal World Article on Fish Diseases and Symptoms. This might help but also read the article for further description as to what your little guy might have. The recommended treatment is also there.

    Eye Problems
    Symptoms: Cloudy cornea, opaque lens, pop eye, swelling, blindness.

    Cloudy cornea can result from a bacterial invasion. Antibiotics may help.
    Opaqueness can result from poor nutrition or a metacercaria invasion (grubs). Try foods with added vitamins and changing the diet to include variety.
    Pop eye (exophtalmia) can result from rough handling, gas embolism, tumors, bacterial infection, or vitamin A deficiency. Gas bubble or bacterial infection can be treated successfully with penicillin or amoxicillin.
    Blindness can be caused by poor nutrition or excessive light. Lowering the light level and a change of diet to include lots of variety may help prevent it.

I have a red beta... he has lost half of his upper jaw... what could have done this? He's in a tank by himself. I tx the water for fungi, and Ich. It seemed to stop the progress of the loss of his head (it's to the point you can see his skull ). Any ideas ?

    Included is Animal World article on Fish Diseases and Symptoms. Scroll down to Symptoms and ICH is there but there is another called Ulcerations on head (hole-in-head). See if the symptoms match anything your little guy has. It would seem to be ulceration, parasite or agression but you have no others in tank. Anyway recommended treatments are there.

    I see that disease is mycobacteriosis.

Hello, I have just brought 2 fish, the one (Sorry can't remember what it is called) has big sticky out eyes. He has fallen on its side and wont straighten up! I have taken it from tank and placed him by himself. He is still breathing but is not swimming. He was fine this morning and this arvo I actually thought he was dead on the bottom of tank. Is he a lost cause or will he come right? I have changed water in other tank to just incase.
They are cold water fish.

    Attached is article on Fish Diseases and Treatment from Animal World. Sorta sounds like you might have something off in the tank. Check tank enviornment and also look down at the symptoms in the article. Could be something like swim bladder disease and treatable. There are many things to check in the tank from temperature to PH and those are also included in the article. You can try - no harm done by trying.

    Then add salt solution or anti-stress to the water.

I've had two angelfish and a gourami start hiding in the last few days. One of the angelfish looked like it had a swollen belly, but the other looked fine. I put them both in the hospital tank and was going to search and find medication today. Unfortunately, the swollen angelfish died during the night and the other isn't looking good. It's fins are looking ragged and its swimming sideways sometimes, but no other obvious signs of anything. I've also noticed that my gourami has red, swollen gills on one side that extends to under his chin. There are no other signs of anything, no heavy breathing, red streaks, mucus. I was thinking some sort of parasite? I do regular weekly water changes and watch all levels. I just did another 30% water change and intend to retake the levels in the morning. Any ideas on what it is? Oh, side note... I had a bully female blue german ram, but she got moved to one of my other tanks about 2 days ago.

    There are several things that it could be and without additional information all I can do is attach the Fish Disease and Treatment article from Animal World. Scroll down to symptoms and look at those and then scroll down farther where various diseases and symptoms are explained. I thought possibly Dropsy because you state the angel fish is swollen and that is a bacterial infection and treatable. It sounds as if you know what you are looking for so I am confident the Animal World article will have what you are looking for. Good luck.

    Sounds like you have a bunch of stuff going on there. Do the white spots sorta look like salt? That is probably ich and treatable. Black nodules on the skin sounds like Ichthyosporidium and is also treatable. It might be some other things but all symptoms of fish diseases are described in the attached article from Animal World "Fish Diseases and Treatment". Scroll down to where the symptoms are listed and provide your guys with the recommended treatment.

    The characteristics of the affected fish is the white patches on the skin of fish. Squirt metapen alcohol treatment in place as much as 2 drops in one gallon of water / 4 1.12) liters of water. The next step give the salt and let some time. Give the hydrogen peroxide to kill bacteria that are attached to fishing nets for 15 to 30 seconds. Or it could also be used malachite green or blue or acriflavin methyline as a disinfectant.
    How to fish treatment that bacterial infection should be given additional space before treating.

Could anyone tell my why my electric blue ram has turned almost white? It has also pretty much stopped swimming and kinda just hangs out on the bottom. Is there something i can put in the water to help it get better? or is it doomed?

    Sounds like it might be a fungal infection. I have included an Animal World article on Fish Diseases and Treatment and turning white cloudy is one symptom of a fungal infection and the recommended treatment is listed. Scroll down the article till you get to symptoms and then treat accordingly. Good luck... hope all is OK

Hi, I have two catfish, around the age of 25 but recently rather quickly the smaller one has developed this weird fungus type..thing. I can't really explain but over his back and sides its scales look like they are just covered or ripped away and replaced with white. I have been told by my uncle it's a fungus but its fins have also been rotting like it has fin rot. The other cat fish has recently showed this as well. I noticed its rays were showing. I took a closer look to see the same kind of fungus on its stomach around the fin. We have had to separate them in the tank as the bigger one keeps viscously attacking the one with the fungus.
I am worried as his eyes have sunken into his head and he dosn't really swim. He just kinda flops down on the floor of his castle then lays there looking dead. I am worried. I dont want to loose my catfish =( they are older than I am
please help what can I do????

    It sounds like a fungus and so you would treat for the fungus and the secondary treatment would be with an antibiotic (which would work for Fin Rot) as well. I have attached an article from Animal World "Fish Diseases and Treatment" which lists the various symptoms and the recommended treatment. Scroll down and see if FUNGUS is explaining the symptoms and then do the recommended treatment. OK? Hopefully the one will stop attacking the other when you get rid of the fungus. Might be something else and various symptoms are identified so check them out. OK? Good luck.
