got some live rock while back and this is on it not sure what it is asked a few buddies that know alot about reefs and they drew a blank
but i think it might be a hidden cup coral aslong with the ones to the left of them
Doe's that happen to be Florida aqua cultured rock? If so I believe that animal is the hidden cup coral, "Phyllangia americana" here is a fair picutre of what I believe it is, http://www.sms.si.edu/IRLFieldGuide/Phylla_americ.htm If you search I'm sure there is better. If it's Pacific rock than it's not
ooo? oddity? I think its a strawberry corallimorpharian a full monty mouth shot would help, hard call on keeping it if it is, they are quite invasive and carpeting
Terry? have another look at the first pic, that really looks like a motile foot to me not an encrusting or hard rock attachment, still need a mouth pic heh?
