green acro?

[michika]

It looks like it, but at the same time it looks like the brown tissue and violet tips (which aren't violet today) pealed away. It almost seems like the brown tissue was the top layer and the green was the underneeth layer just prior to the skeleton.

I'm starting to think this second acro crab, the top one in the picture, is to blame. I'm trying to find out if he is actually an acro crab or just some snotty little wannabe who's causing damage to my corals.
