Keyhole Cichlid Compatibility
I have a 38-gallon tank with various community fish (see below) plus 2 keyhole cichlids. I have no idea if the keyholes are male or female, but they do get along fine. Tank is heavily planted. My question is, do I have room for 1-2 more dwarf cichlids, maybe cockatoos or German Blue Rams? If so, should I get a breeding pair or will that set up too much conflict?
Other fish: corys, bristlenose, clown pleco, otos, platys, rummy-nosed tetra.
