Ed, you will be able to keep the majority of non-photosynthetic LPS corals by spot feeding as long as tank parameters are kept inline. Stock up with Fauna Marin LPS+ pellets, Argent brand Cyclop-eeze, PE Mysis of Reef Nutrition Mysis Feast. Also while you are at it, if you don't have the already; a turkey Baxter and Kent brand sea squirt which will assist you in the direct feeding of the corals.
