A couple of unanswered questions, I've herd in the wild they can get quite large, I forget (Google may help) but I just remember when I was told how big they can get I was shocked. Do they need to be fed....I would say so. I mean Givin the price and color brightness, I'm not gonna starve mine and "see what happens" all I know is when I put my hand in the tank, tentacles come out. It happily accepts food day or night. They are expensive but I tell u what, not only is it one of the brightest corals in my tank, like seriously catches your eye from across the room it is the most interesting and entertaining coral I have. Everyday when I turn on the lights I'm excited to see what shape it decided to be . Not saying everyday it's a new one but it's shown me new position enough to keep me interested in anticipation. I'll post the pics :) it's been a happy easy coral since day one for me, on the substrate under t5s... I feed it here and there and god bless it.. I love that thing!
