At what age/size have you been able to sex swordtail fry? I have been reading that male development can be delayed in swords (which I have personally experienced when my M/F pair ended up being M/M!) These fry are right around 6 months.

6 months is right about when you should be able to sex them. Sometimes it takes a little longer but by 8 months there should be no doubt as to sex.
