Depends on the size of the fish, their individual temperments and how they get along. I'd say with the Red Oscar, Festae, etc...see how they do and if you have more room you COULD get another smaller cichlid like a convict or FM. I was just looking at Rapps site and he has some awesome color morph wild FM's, and Convicts.
ok, how aggressive are female fesates???? i know this is a stupid question really i know it depends on individual fish but, over all are they really aggressive? and how about carpinte??
"agression will dictate any other stocking. if anything it will have to be small as scubasteve said" wot do you mean by this???? what will have to be small?
