Sneaker male or colorful female macmasteri?

[Hellfishguy]

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?

Looking at yours and looking at my male, I would guess a male. Do the ventral fins ever darken?

 

[Hellfishguy]

The ventrals are always yellow. The male attempts to court it instead of trying to kill it.

Pict. # three is the other male?

Yep. I don't have any doubts about the sex of that one.
