My work has a 20gal fish tank it has 5 fish in it. One common goldfish has what looks like to be green stuff/ fungus in its eye. Im not sure if its blind. I can also see a tumor or cyst on its side that has burst about 2 weeks ago and then reformed. The fish appears to be swimming on and i don't see any worms or spots on it. Im not sure what to do. None of the other fish have this problem.

    Good observation! I would first take your goldfish out and put him in a fresh tank by himself IF the others do not start to pick on him. I would get medication for Goldfish ich. The parasites fall to the bottom of the tank, then in a few days reattach when the fish sleeps. At least this is what I am guessing. Cleaning your original tank's substrate really well and treating the tank for ich is a good idea as well. If your other fish are not attacking your goldfish, then you may leave it in there. If it is Ich, remove any live plants. Raise the tank temperature to 80˚F, (speeds the growth and cycle of the parasite) do a 25% water change, (make sure your ammonia and nitrites are 0, if not do a larger water change up to 50%. Add aquarium salt 1 teaspoon per gallon. In 12 hours do a 25% water change, add 1 teaspoon per gallon again and repeat for a total of 3 times (so 3 doses of salt and 3 25% water changes). After the 3rd 25% water change and salt dosage, do not change the water for 2 weeks. At that time do a 50% to 75% water change to remove the salt.

    Fish are dying so there are 3 logical choices. 1. they are aging really fast which is not likely. 2. the tank conditions whether it be chlorine, PH, temperature are off. Check all your tank conditions throughly. Is the substrate been cleaned out. How's the water? 3. The fish have some sort of disease. Animal World Article Fish Disease lists various symptoms that may be occuring in your fish. The corresponding medication/treatment is recommended.

We a 55 gal tank, all fresh water fish. What does it mean when an angel fish twirls around? We had three. One died after twirling around. The other started to twirl now it's fine. We bought some neon fish also . Maybe they brought in a disease?

    Usually behavior problems are a result of tank conditions, temperature, PH, Chlorine etc. This could also be a condition called Swim Bladder Disease which occurs as a reult of too much food, eaten too quickly. Animal World article describes Swim Bladder and recommended treatment Fish Disease.

    One more thing, I fogot, most articles recommend that you stop feeding your fish its regular fish food for a day or two and instead feed it peas to relieve constipation.

I have had several different species of tropical fish that have succumed to a puzzling problem. Initially the fish body appears to be hump backed and crooked. Then I notice that they begin to hide and have trouble swimming. They eventually die. Anyone have any idea what could be causing these events?

    It sounds like one of the symptoms of Fish Tuberculosis. Although there are some treatments for it, most aquarists recommend removing the fish as soon as possible because it is infectious and can spread to other fish. A more complete description can be found here Fish TB

My kids fish are already dead, but i was woundering from what. Someone told me it was ich but I bought the meds for it and it didn't help. They had big grayish/whithish circles on each side of them like ther scales were falling off. They looked like their fins where starting to ripped up. They where always hidding and then had no control on how to swim the looked liked floating sardines pointing staight up and down letting the current from the pump just take them around. I want to buy new ones but I dont want this to happen again a life is a life and my kids where crying and if this happens again I would love to know what to do. I never had fish before so I am kid of dumb on this situation any infomation would be greatly appreciated thank you

    If you have a good aquarium setup, with a good filter and heater, and you cycle your aquarium, then many diseases can be avoided. Cycling is simple, yet understanding it is perhaps the most important thing for successfully keeping fish. You can learn about it here Aquarium Nitrogen Cycle, Cycling Aquarium Guide

    I do not agree that your fish had ich, ich looks like little white spots. A good analogy for ich is it looks like your fish got sprinkled with salt. Big gray/whitish circles indicates a different disease, more likely a fungal or bacterial infection. (Ich is a parasitic infection)

    Check out the fish diseases page above. It has a quick reference chart that lists fish diseases with a quick description of the symptoms... then below that there is an in-depth discussion about each... their symptoms, causes, and how to treat. That should be of great help to you in the future.

    Most often a cloudy tank is a tank condition problem. Has the substrate been throughly cleaned and what is the PH? Check the PH. Scroll up and look at symptoms in this Animal World article and look at what best describes your condition and recommended treatment is listed. Also, found another article which might help White flaky stuff

I have an african brown knife that is starting to get a whitish coating or film over his body and had become very lethargic. Actually I have just been informed he had died. Anyway my second african brown knife is starting to get the same symptoms (yet none of the other breeds appear to have it). Any ideas out there what the problem is and most importantly how can I correct it to save my fishs life ? Please help.

I have two iridescent sharks 14 and 16 yrs old 13 and 15 in long, I have had them forever. They have been in a 55 gal ac. for many yrs but have outgrown it. I tried to re-home them but after leaving them in their new home my husband and I decided we couldn't part with them. So we brought them back to their 55 gal tank and went shopping, of course they stressed and had to be treated for ich. We got a 150 gal tank and about 3 weeks later moved them, they stressed again and we treated them again with melafix. They were fine for about a week and then the smaller one began to fade the grey turning more and more pale and developed a yellow coloring behind both eyes and yellow tint to the fins. Both fish are eating and swimming around fine there is only a school of giant danis in the tank with them. Anyone know what's going on, the change in color has lasted about 10 days.

    Pangasius do fade with age and become more silvery, though I'm not sure about the yellow coloring. They do get very big and are a schooling fish, and are also nervous critters. But it sounds like you are aware of all that and have taken very good care of them. Being active and eating are good signs that they are not stressed.
