Fish/parrot fish


I recently bought a 75 gallon tank that came with 4 parrot fish. I have had freshwater tanks for years but with community type fish and no ciclids. They do pretty well but the smaller of the four is going very pale and is being picked on by the bigger fish. So not sure what to do here. Feel the pale color may be a sign of distress? Time to rehome this one maybe? And what is the best diet for these guys. The tank also came with two small puffer fish black and yellow guys. Not sure best diet for them either. I am worried that the tank size is too small for what is in there. The puffers are maybe 2 inches each and the parrots are about 4 each. Any info on these guys is greatly appreciated. They are great fish love the personalitys but just want them to be happy and stay healthy. Thank

Hi Melissa,
  Yes the pale color is probably a sign of stress. One solution is to add a whole bunch of structure (rock, wood, plants) to the tank  to break up the space -- that should help with reducing aggression.

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.
