I hope I have posted this in the correct place. Kindly point me in the right direction, if not. Can anyone help me identify? I think it is Rhodactis, but not 100% sure. I just bought it the other day, but can not remember what it is for the life of me. During the day, she opens up and spreads almost entirely over the frag. At night she shrinks up to nearly half her size. I want to make sure I have her placed correctly in my tank. (I don't think I do at the moment) TIA!
