10-11" Male Jag
My female Red Devil was the only thing that kept my Jags and the other fish in check. Have you tried it at least? Female Amphs are great community cichlids if you have the right mixlol my Jag would kill her, and she would give him some battle wounds. I like to keep my bruisers alone so they don't look tore up all the time.
how big is his tank and does it have a couple dozen caves to divide territory and keep them out of their lines of sight ??Ive tried fish with him in the past...always ended the same; he would be "fine" with it until one day I came home to the fish disemboweled with missing eyes. lol
