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.

Is pop eye contagious?

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

    It sounds like wounds or a bacterial infection. Are there other fish in the aquarium? If it is bacterial, try a fin rot medication. Although many fungal treatments have anti-bacterial ingredients, I would try something specifically for rust or fin rot. Also he may be scraping against rockwork or other ornaments.

I have two Shubunkin Fish. I have the right size tank, right water and temperature. One just swims upside down all the time. It eats like it's fine, but as soon as it finishes eating upside down it swims. Is this a problem? I have had it for six months now.

    It sounds like a swim bladder problem and is not uncommon in goldfish. I found this article that can help Our Goldfish Swims Upside Down. Good luck with your fish!
