so I rarely breed, but I am raising my own Tilapia fingerlings for next spring... even on bigger fish, harvested this fall, I didn't do a very good job sexing my breeders, & ended up[ with extra males fighting over one female...
to sex Tilapia, you apparently examine the fish, fish with 2 vents are female, fish with one vent are male... somehow the distributor is able to sex them at the fry stage... it's said, that on smaller fish, you should use a cue tip with blue food coloring, on it, giving it a swipe over the vent area, I'm thinking a magnifying lens would make this easier...
my understanding is that all egg layers should have this same physical trait... live barerers I believe would usually have a special shaped fin, that is used to impregnate the female...
so on something like angel fish ( they would require actual handling ) but assume they could be dyed at the vent, & be able to tell if they are male or female???
