Recently added a rock krib cichlid into my 55 gallon community tank. He is in with a school of small tetras, rainbows, an angelfish, corys, pleco, and a few others. So far so good everyone is getting along great. Had issues between the rock krib and my white blood parrot (juvenile) so i moved the blood parrot to a different tank. Am curious if there are other species of cichlid that will do good in my community tank with the rock krib in there? Not sure if 2 different larger cichlids will cause issues for all my other fish. Theres also a bolivian ram in my 55 and he has no issues. Rock krib is about 5.5 inches at the moment. If possible would like to put 1 more cichlid (3-6 inches) in this tank and call it stocked. Thanks
