The first spawn, I am told, fares poorly. But given that these clowns have spawned before and are in a routine, there's more to keeping them alive than just feeding the rots to the tank.

First, and there are experts here that can correct me, you have to be aware of which night they will hatch on... turn off your power heads and dangle a little LED light source over the eggs so they will swim to the light after hatching. Then you place them into another tank where you will feed them a couple times a day, at the least, rots until they grow larger. There's a whole process to keep them alive. If they spawned on a rock that can be removed then half the battle is over, simply remove the rock to another tank where they can hatch and grow unmolested.

There are quite a few folks on here that have raised them, I've had mine spawn once... but I don't have the will/ability/time to keep the fry from doing much more than becoming food for the other fish.
