Well Andrew Let's figure it this way, my group of Cacatuoides 1male 3 females which have around 70 plus in a brood gives me around 4 to 6 grow out tanks for the fry in a average 6 month period. When I fill all those tanks I stop pulling fry and let happens what ever happens inside the breeding tank. When that does happen, i normally end up with fry growing up in the breeding tank. I once had 7 tanks of different broods of fry from a single pair. Sad part for quite some time I had mostly females in those broods of fry I grew out. My last batch of fry was 95% males, thank god.
