yes, feed it on the regular bases. unfreeze frozen food like cyclopeze, or any other vitamin soaked meaty food, turn off the powerheads, put some food on top of each mouth (I use surringe without a niddle) and let him eat it. if the coral is very sick first few times it will take him longer to eat the food. hope i didn't miss anything in the process. some say it's best to feed few hours after the lights have been off and the coral shows feeding tenticals, but i feed mine when it looks nice and swollen, and it takes food as well. in fact, when some corals are very sick, they might not going to spread their tenticals for feeding at all.
