Not sure if I understand what you are suggesting here.
But if you think that the males have had their wicked ways with the girls, then you haven't understood what JC and I have both said.
The tets are eggscatterers and as such, the eggs are infertile till they come in contact with the males milt as the frenically race thru plants etc, scattering eggs and milt in all directions.
MODS. Do not censor please.
A little sex education never hurt anyone..
After this chase etc, the fish are very hungry, and proceed to cut down the number of babies hatching by eating any eggs that they can find and if left long enough, any babies that get thru, so as you can see you have to be prepared and know what to do and when.
Best to have more than one male too.
