Does anyone know what this might be bought a piece of coral and it had a bunch of these. Looks like some type of anemone. Sizes range from a half of inch to a quater.
no dont get a peppermint shrimp. there are 2 types of peppermint shrimp; one type wont even look at aptasia( i know its not an aptasia) the other type might possibly think of looking at aptasia to eat it. but both will eat corals. Just kalk them, they might be rbta but rather safe than sorry.
