Someone on RC is saying stichodactyla helianthus which is the "dreaded" Atlantic Carpet Anenome. Eats everything including clowns. The problem with that is, it doesn't look like stichodactyla helianthus! Those ones clearly look different to me. I could be wrong though.
I don't know but I had a hard time even sleeping last night knowing my new mandarin was hanging out beside it. He made it through the night though. Apparently they should know to stay away from the thing. Maybe the little fish got mesmerized
Brad I agree, it looks a bit different from yours but it is way smaller so maybe thats why? I am going to take a pic today once its all open. In that last pic it was kind of closed still after eating.
