1st Big mistake

yes you should try and feed them now.

 

Never forget that clowns are fancy damsels. Damsels are tough as nails. Just put small amounts of food in, if they don't eat right away just be patient. Small amounts of un-eaten food is better then lots just rotting in there. Post us a pic when they come out of hiding!

 

Sometimes fish won't eat for the first day because they are too nervous from the netting and being in a new environment, etc. I've never had one that wouldn't though. If I were you I would stick a little bit in over them and see if they go at it. I just wouldn't put too much in because if they don't go for it that's food wasted or potentially food for unwanted algae.
