ID Help, I've done all the research I can and cant find this guy... Hitchhiker of unknown type, what I do know. Green has tentacles and will retract into a hard stony base. Was two but killed one then had second thoughts on other after I released it has a encrusting skeleton and cant be an anemone. This one is 3-4mo old and growing about the size of a Zoa as I made sure one was in frame. Second shot (with red probe tip) was after I touched it showing it closed up. It is growing dome shaped and its base keeps adding more tentacles/heads. ID, keep and watch or smite it?
