@ C Grima: Normally I keep between 10 & 20% of every brood, but unfortunately some of them has to be culled at a much later stage because they stay at wild colour and do not turn black like the others, due to genetics I guess! Normaly they turn black at around 2 to 3 months old.
@ Martin: Woww you were very close man because last night I wasn't in the sleeping mood and I have counted 1608.
@Kristofer: That is a normal brood size before culling but to get quality up you have to get numbers down, That is a breeding tank which measures 3ft by 2ft. and when the parents are ready from breeding I remove them to another tank and leave the eggs alone to hatch, when all the fry becomes free swimming I carefuly lower the water level to around 10 cm, as said above. As from the first day of feeding bbs I start to do daily water changes.
