get some mysis shrimp. in a separate container, let it thaw in some tank water, rinse off with some RO water into a net, and put it into your tank! make sure no water from the thawing process goes into your tank. my clowns didnt eat for a week when i bought them. i soaked the mysis with some garlic and they gobbled it up right away.
are your clowns ORA bred? if so, try some ORA pellets since that is all ORA mainly feeds.
laying in the sand sounds somewhat normal, but during day time-seems weird. keep in mind that clown fish are extremely strange fish, just look at my avatar. that is my armor of gods zoa frag that my picasso hosts. extremely out of the ordinary. when i first got him and his ex-wife, they never really swam around the tank. since you just got them, chances are that they are a little stressed..have you tested your water?
have you eever owned a pair of clowns before? if so, is their "funny swimming" something you have seen before?
