I have a 2 year old female Angelfish, it is about 3.5 inches and in the last month I noticed a bulge that protrudes on the right side of its body in the center. There are no damaged scales, my fish is still eating normally and swimming fine and doesn't seem to be in any distress. Does anyone know what this could be, is it an enlarged internal organ, parasite, or disease? And what can I do to try and help this fishy out.

    It's possible it could be a tumor, but it's also possible it could simply be constipation, try altering it's diet for a few days, feeding blood worms for a couple of days should help flush out any problems, however if it's a tumor i'm afraid there's nothing you can do.

My electric blue dempsy is acting very strange we have had them for 4 days and they seem to be just at a stand still in the corner of the tank it's either at the way top or in the middle. I don't know why they are doing that they started doing this tuesday.

We have a pond with koi and comets. The comets are varying ages from 1 yr. to 3. In the last week we have lost 9 comets. At times they are at the top of the water doing what looks like gasping for air. Then at times, they look like the are sleeping on their side. Don't know what to do help?

My Goldfish is 2 years and a half year old now and he has been healthy for the last half a year, today, which means these defects just grew visible overnight, I see that he has cloudy eyes, 2 red streaks in his fins, white dots on fin, and his scales on one side of his body seem to have clear white skin hanging all over it, and it is kind of red too. What could be wrong?

Is it safe for a larger cichlid to eat a smaller cichlid with a swim bladder issue?

I have a jack Dempsey that I had for about 6 or 7 years and he is not swimming correctly. He lost weight but still eating or trying to at least. His color is still there but a little pale on the under belly. Could he be getting old or is this a disease.

My one year old Butterfy Koi have stopped eating over the past 4 days and tend to congregate in the corner. One has a slight fin separation. They are 10 to 14 inches in size. Their PH is 7.0, there is no ammonia ( I've scooped out the uneaten food) and they even left their favored blood worn uneaten. I changed their filter but am at a loss of what to do next.

My daughter's tank was used for sick tank a couple of times. Cory's threw eggs in a community tank and eggs were moved to the uninhabited sick tank (no medication at that time). Shortly thereafter, something black (looks like swimming black pepper) appeared. Tried a magnifying glass but they move too fast to see. Cory fry are about 3 or 4 weeks and the pepper keeps on multiplying. Fish seem fine and healthy. Afraid to move to new tank.

One of my fantails was sick--kind of a big bulge on one side and swimming a little crooked. My pet store sold me Maracyn. I put the fish in his own tank and treated him, but the bulge is getting bigger and he's barely swimming...hangs by the filter most of the time. He still wants to eat, but it's a struggle.

I read your chart of diseases and think it could be a tumor or dropsy? I know for a tumor it said destroy the fish...I hate watching my fish suffer, but I don't know how to help him die....

    There has always been controversy about the best way to help a fish die in a humane manner. One that I have tried is to put them in the freezer. Check out this page for more information Euthanizing Fish
