It is living (relatively peacefully with 2 juvenile cichlids, a Green Terror, and a Salvini, and 2 baby cichlids, a Firemouth, and a Convict, and has not really been overall aggressive (any more an any other average American cichlid) to any of the other fish. The fish is colorful, but not overly so, and constantly “digs” pots, as though getting ready to spawn, but has no mate, nor any other unrelated cichlid in the tank of breeding age/size. In light of the relatively peaceful temperament, and the digging, do you think I have a male or a female, also, can this arrangement work long-term? What about if I add an Oscar? Thanks in advance,
