They mature fast. I have a pair (female 1" male 1 1/2") guarding eggs as I type. By the time you figure out how to vent them they will be large enough to sex with certainty
male or female convicts?

ok guys im back an with my 5th batch i got an eye for this. at like 1/2 inch you can tell which ones are goin to be male an female an i already got mine sperated 
at this length the females will have a tiny orange spot on them you have to look real hard to see it but all females have it. some orange spots will be bigger then others but they all got it. an for the males they dont have the little orange spot. its easier to do this if you have "for me" more then 20 together.
