What to feed cinnamon clown fry

[Hwyman]

Hello all,
I just found that my clowns successfully bred and hatched a clutch without my knowledge! They have been in their own tank for a month and there are quite a number of fry now inhabiting a rubble pile. So far, they seem healthy. i was just wondering what, if anything, should be added to supplement their diet?
I would estimate they are 3-5 days old now.
