We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
nr1 I believe is a female. The crecent shaped Pelvic fins, the small pectoral fins, together with body and head shape indicates this to me, even though there's more odontodal growth than a female should have
Nr2 and 3 are obious males. Straight pectoral fins, large pelvic fins, lots of odontodes and broad heads.
1 - female - fat body shape, more rounded head and shorter odontodes
2 - male - pointy head - angular body shape - long odontodes as clearly male as number 3 if you ask me
3 - male as above
