Nice fish

I think the 2 on the far right are both females (top and bottom one). Maybe the one on the far left as well (bottom left).
The others are males imo

Top pictures: I think all three are males.

Bottom Picture: I think left two males, one of the ones on the right definately looks like a female, the other looks more likely to be female.
