AboutRon 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.

Expert: Ron Coleman Date: 6/20/2008 Subject: blood red parrot fish
Question my fish has started developing black/blue markings on both sides of its body and also its head. they have appeared over the course of about a week and are not on any of my other fish.i have a slighter larger orange parrot and have seen this one bump into the one with spots.it is eating very well and there are no other problems obvious. any advice would be appreciated
Answer Hi Chanel,
These sound like typical fish "bruises" that should heal if the fish is left alone. Keep an eye on things to make sure that the larger fish is not attacking the smaller one.
