KD,
Again though, the clean-up crew cleans up things that are not doing well...I don't think they would eat healthy polyps. Perhaps something is wrong with the colony that you cannot see, or perhaps there is algae etc nestled in amongst the poylps or underneath the rock? Just a thought.
From what I can tell from the pictures, I do not see anything blatantly wrong with your colony...and sometimes it takes time for a colony to open (up to two weeks). In the last picture you posted, it looks as though the polyps are slowly begininning to open...I can see a little color on a few of the polyps. So even if you lose a few of them, I would not take the colony out...all you need is some of the polyps (hoefully most!) to survive to have a sustainable population.
The last colony I recently purchased, as soon as I put them in the tank, half the colony "disintegrated". No idea why, but the same thing happened to the sister colony at the LFS when I went back to talk to them about it. But, the good news is that the remaining half of the colony stayed closed for about a week and a half, then openeed up...so it turned out OK.
These are hardy animals, so honestly do not stress it....giver them some time, and make sure they get a decent flow on them, as IMHO, zoanthids really seem to do better and propogate faster when they are in a decent flow.
HTH, and keep me updated on how they do.
