I have this decorator crab that always tries to be Fresh to Death and steals any small frags I introduce. Now, as this is what happens in the wild, I am assuming they wont die, unless they crabs don't care about the coral polyps and will settle for just their skeletons. Will they die? or is the reduced amount of light they receive living on this dude be enough for them to multiply? I have a stock Biocube 8, and the crab hides fromt he light, although I do see the GSP and zoanthid extended at times, at least daily, just not constantly as it would be if planted.
