Keri Anne Posted September 27, 2007 Report Share Posted September 27, 2007 How old are they, takes a while for the males to develop their gonopodiums (basically they have to hit puberty before the bottom fin changes.) Quote Link to comment Share on other sites More sharing options...
Guest Posted September 27, 2007 Report Share Posted September 27, 2007 Yeah I have platys about the same size as yours and they all like females I think it takes a while for males to develop a gonopodium. Quote Link to comment Share on other sites More sharing options...
HaNs Posted September 27, 2007 Author Report Share Posted September 27, 2007 3-4 weeks i think Some are hitting 20mm Temp is 24c Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted September 28, 2007 Report Share Posted September 28, 2007 If they're all females they haven't hit maturity yet. You'll get a 50/50 split. The males anal fin will slowly turn in to a gonopodium. Quote Link to comment Share on other sites More sharing options...
Keri Anne Posted September 28, 2007 Report Share Posted September 28, 2007 That's too young to sex for platies. Quote Link to comment Share on other sites More sharing options...
