+one for two males.
Adding just one female at this point, is likely to result in one of the males getting bullied by dominant male seeking to claim breeding right's.
For such a small fish,, they can be nasty with each other during battles over breeding right's to just one female.
Adding two or three females if floor space in tank permit's, would be the way to go otherwise,, I would leave thing's be or remove one of the males should you decide to place but one female in the tank.
