The texture and color doesn't look like any of my other shrooms. It's not a carpet anemone right? Can't get a better picture at the moment because it's still curled up.
I'm leaning toward Rhodactis now but the color really surprises me. The bumps aren't as pronounced as in a Ricordia. Noticed this morning part of its body was torn (the fold on the right side is formed from the rip) so that's probably why it looks so ticked off. Bought it as a loose coral laying on the sandbed for $8 so no complaints here! Best picture I can get of it in the cup.
