I recently bought a two spot pike cichlid and put it in my 30 gallon tank. right now it is about 3 1/2 to 4 inches long. the only other fish in the tank is a striped raphael catfish that is about 8 iches long. so far the only food that the pike cichlid will accept is frozen bloodworms and earthworms. he wont eat anything else. Does anyone have any experience with this kind of cichlid and do you know if it can be trained to accept prepared foods?
