i feed my spawning pair...
spectrum flakes 4x per day
mysis,rod's orig,cyclop-eeze, fish caviar 3x per week. dif days for each.
most likely they are new at this, but will eventually stop eating the eggs. if your set up and ready to raise the fry then pull the the eggs as late as possible. if you pull them on day 5 or 6 and blast them with bubbles for 1 or 2 days then you might get lucky. also get rid of any threats to the clowns. i've read and seen if a spawning pair get harrassed enough they will eat the eggs. i guess their thinking is if something is going to eat their eggs then it will be them first. and the same goes for the almighty hand. once my pair lay eggs, i try to keep myself from sticking my hand in the tank as much as possible.
