keeping a red devil and jaguar together?

[pi-eyed]

^^ only thing is that was a growout, i think the OP plans to have these fish in that tank for life (though i could be mistaken

Ahh..Good point..I put those fish together with grow out in mind not for life. You are very correct on each of those cichlids becoming psycho.. The op could always try the crowding technique--however results can be disasterious. So much depends on the individual personality of each fish.
