Does anyone know how much to feed these juvenile clowns?

So I got a paired set of black ocellaris clowns, and I'm wondering how much I should feed them... of course every single fish store says something different when you ask how much to feed a fish, but since they are juveniles, does anyone know how much I should be feeding them? I'm currently feeding frozen mysis shrimp. Thanks

Small amounts once or twice daily is all you need to feed. If you overfeed you'll end up with excess nutrients that can cause unwanted algae growth and a bristleworm bloom.
