I got a nice torch coral with 2 polyps for my tank yesterday and attached it to the live rock. The tentacles were not out, but I figured that was because it needed to adjust. I just saw my hippo tang go up to one of the contracted polyps and pull a couple of tentacles out! I thought tangs were OK with coral. Anyone have a similar experience? It's fine with my leather, colt, brain and candy cane corals. Not like it's not well fed; far from it. Not much I can do, I guess.
