I have always let the clown pair take care of the eggs until they hatch. On the night they are suppose to hatch i turn all my pumps off and put a brite flashlight on the top of the tank. As they hatch they will start to go towards the light. Then i remove them from my main tank and put them in a smaller tank that has no flow what so ever. For the first week they eat rotifers after that you have to hatch brine shrimp everyday for the next two weeks and then slowly try to get them to eat frozen food
