Question Our Red Devil is afraid of the night crawlers we've attempted to feed him. Any suggestion of a different treat for him? He's very aggressive when eating his pellets, but drop a worm in and he hides from it. He is alone in a 55 gallon. We've had him for 6 weeks now, is he maybe still getting used to his new home?
Answer Hi Kim,
I would give him time and eventually I bet he will eat them (and likely love them). Cichlids such as red devils are very intelligent and it takes them quite a while to get used to new things (and yes, he can easily recognize people as individuals, so he is still getting used to you).
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.
