I am suprised nobody spoke up. I don't know much but I'll try to help. I do know they're zoanthids. They get most of their food from the sun but are not too light hungery, they are also filter feeders and can be target fed. They're one of the easiest corals to care for.
LOL...He said coloration...they have such silly names for them... purple gorilla nipples, green eyed dragon, just to name a few of the crazy names, so I couldn't tell him what coloration these are called.
