I got a bleached goni from my LFS a few years ago. It was completely white, and I figured I'd try bringing it back to life with some TLC. Like Smitty said, the best way to feed them is to cut the bottom off of a soda bottle, then put the bottle over the coral so it won't be disturbed by other animals. Then use a turkey baster to shoot some food into the bottle. My goni always ate... But some corals do, some corals don't, it seems.
