Back when I had an assortment of corals, I didn't feed the smaller polyped species anything. I did, however, feed the larger ones small pieces of fish and/or shrimp.
I believe the main cocern is just getting them into the tank and placing them on the bottom first..work your way up durring the week as they acclimate to the lighting.When receiving coral via UPS or FedEx, how soon after should you try to feed?
