Hi I am in need of some help. I have an aggressive blood parrot, 7 in female. She won't stop harassing a red peacock cichlid I have. There is a 5 inch black convict in the tank, yes I know about the pH differences and it's a bad idea and stuff but they do completely fine together. The blood parrot on the other hand I've had to place in another tank in order to keep her from terrorizing this fish. I would like to get another type of bright colored cichlid to get the blood parrot to distribute the aggression evenly amongst everyone. I saw this nice eye biter at the fish store. It is about the same length as the peacock and bp. My only concern is the eye biters mouth, I know they are very large. I have a 6 inch bichir in there as well and was wondering if the eye biter may find him as a treat. Will the bichir fit into his mouth? Will the eye biter maybe help with this situation? I you have other types of cichlid recommendations please feel free to tell me. This is a 40 gallon breeder tank.
