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 ask me questions about why your goldfish are sick -- they are almost always sick due to the way that they are sold). Also, 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. Thanks.
Experience
I teach 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.

Question
about 3 weeks ago i was given 12 African cichlids ( I'm not sure of exact kind ) i have a 40 gallon tank most of them are baby's except 3 the other 2 are doing ok i guess but the one stays by the filter and i noticed its tail and fin is chewed up i haven't seen them be aggressive towards him and also he hasn't eat in days. so that was my first worry!! also i noticed my fish are not how they say they should be they don't go to the top for food they seem stupid!!! and they are not very aggressive like i had heard so what's wrong with my fish? is it me or them?
Answer
Hi Stacey,
The fish are not stupid, they are just frightened and confused about now living in a new home. It is also clear that one of them is beating up the others.
