I have a 55g tank with a green terror male,convict male, small jack dempsy male, female jack, a brazillian female, a salvani male, firemouth male, and a red jewel female. they are all under 5 inches. i added a 3 inch fire mouth and it nearly got killed. i am in the works of setting up a 125g will that help?
One thing that might be helpful is to use just regular flake food. a lot of the time cichlids won't eat pellets because the are to shy to come to the top. flake food will sink and float around the tank and catch his attention try that and let me now
