I've had this pair of Apistogramma macmasteri for about a year, or at least I assumed they were a pair when I first obtained them. The fish I thought was the female has become quite large & colorful, with somewhat extended fins, although not to the extent of those of the definite male. The "female" would occasionally disappear into a cave for several days, but there were never any fry; this hasn't occurred for at least 6 months. Just what do I have?
