how big are the 204's ??? sorry from those photos i cant really see too much but heres a pic of a couple of my 204's.... male is in the cave and you can see clearly the males have a hairy backside compared to the females smooth backside!!!
so pull your fish out of your tank again and have a close look at the rear of the fish for hair.... normally very clear out of water...
Looking also at the pectorialfins I would guess that the fish on picture 6-8 is a possible female. The rest are all male I'm afraid.
Subdominant males don't display a lot of odonthodes on the tail, not nearly as much as the dominant male. Let them settle down for a few months and then look again. Maybe it is more obvious then
Hi, and thanks for your answers, I hope to have some male and some female, the choice that I had to do was on a total of six fish. Maybe it was better to take them all? Anyway let's see how they develop between several month
