I have 14 inch long peacock bass, a 10 inch long maneguense/jaguar cichlid, and a 9 inch long jack dempsy.. my jaguar cichlid just absolutely bullies my peacock bass and beats him up, i thought adding the dempsy would help the peacock bass by putting enough aggressive fish in there so the jaguar cichlid backs off a little but the jaguar cichlid is just a complete bully to the peacock bass but doesnt even touch the dempsy.. any thought to a new tank mate to help balance out the tank to get the jaguar cichlid to stop? maybe more bass the same size? or even a different more aggressive fish?
