I have a pair of GB Rams, a pair of Bolivian Rams, a Bristlenose, 5 Cories, and 5 Pineapple Swords in a 60 gal. My GBR male chases everyone in the tank non-stop now, all except the BN Pleco. I'm sure being cichlids this is normal to a degree. Would there be something I could do to slow him down? Maybe add a schooling fish of some type?
