About Ron Coleman
Expertise
I am an expert on cichlid fishes, particularly New World cichlids. My broader expertise includes the behavior, ecology and reproduction of fishes in general. (I am NOT an expert on Goldfish). Please do not use abbreviations, such as "my GT has a swollen eye" because I don't know what a "GT" is. The more clearly you can explain your question, the better chance I have of understanding what it is that you seek. I keep fishes both as a scientist and as a hobbyist and I currently maintain about 140 aquariums.

Experience
I am an Assistant Professor at the California State University, Sacramento in the Department of Biological Sciences, and I run a website, called the Cichlid Research Home Page . I also write for many popular aquarist magazines, and I am editor of Cichlid News magazine. I am a scientist and I spend my time teaching fish biology, ecology, behavior and evolution and doing research on the reproductive biology of fishes, particularly cichlids. I do research in the laboratory and in Costa Rica, Nicaragua and Mexico. My main interest is understanding the evolution of parental care in fishes. I am interested in encouraging greater public awareness, understanding and participation in science.

Fish - My fish cannot see!!!

Expert: Ron Coleman - 11/6/2009

Question
My fish, Troy, just had a bad case of fin rot and is recovering (we still are giving him Rid Fungus and Mardel). Last night he stopped seeing his food. We got him to eat 2 pelts but no more. We think Troy can see light and shadows. Me and my mom think that he doesn't have pop eye, but I'm willing to try anything now.
Thank you

Answer
Hi Gabrielle,
Hmm... why do you think that he cannot see his food? He simply might not want to eat it.
Have you been doing regular water changes? You should be changing 25% of his water, once a week, EVERY week to keep him happy and healthy. Have you been doing that? That is the most important
thing you can do for a fish. When water quality gets worse, many fish stop eating.
