Question I recently bought a baby severum chiclid, approx size 1-1.5 inches. I put her in a tank with another severum twice her size. During the first night she sustained an injury to her pelvic fins, one of the pelvic fins is almost gone. I immediately seperated the two fish. The injured one appears to be a little better, she is eating, but hiding alot. Will her pelvic fin grow back? If not, what limitations will she have? Thank you for your time
Answer Hi Jerry,
Whether the fin will grow back or not depends on how far down to the base it was bitten. If the bony elements are gone then it won't likely grow back properly. If the "filmy" part of the fin is gone, that grows back quite quickly and easily.
In the worst case where the bone is completely gone and the fin doesn't grow back completely the fish will still be fine in the long run and this shouldn't have any significant limitations for her.

THANK YOU you set my mind at ease!!!!! That fish is like another son to me, and you responded quicker that i thought.
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.
I am an Associate 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 was editor of Cichlid News magazine for several years. 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.
