I have two peacock males. I have multiple types of corydoras, bichirs, featherfin squeaker (lace catfish), rosy barbs, pleco, yoyo loaches, petricola catfish, rainbow sharks, pictus catfish and baby garras.
I love peacock cichlids. So totally chill. I have not seen mine pick on any fish or each other. My bichir got moved because even if he was well fed, pictus catfish and petricolas came up missing.
