what is eating my zoos?

[dble_g2k]

Given the following what would you say would be eating a nice colony of zoos?
decorator crab
a pair of skunk cleaner shrimp
a huge anthropod population
a cleaner wrasse
No one else seems to be interested in them, but after enough observation I've narrowed it down to these guys. If you've got another idea plz let me in on it as well
Thanks in advance

hmmm u havent noticed any of those actually eating away at the polyps have you?? how long have you had the polyps??
cleaner shrimp shouldnt do anything i have one in my tank and hes fine.... decorator crab might try to pick some off of your colony and attach them to his back but he wouldnt eat them he would only do that until he is camofllaged enough....
anthropods wouldnt eat them either..... cleaner wrasses are reef safe so i dont realy think its those....
im thinking if your polyps are new that maybe they are just dying off themselves not so much being eaten.... i had bought a rock of green button polyps at my LFS the rock had about 60 of them all were shrivilling up and dying for no apparent reason .... all of them died except 6 of them.... those 6 are still doing fine and this was about 6 weeks ago and now they are starting to multiply.... i can not figure out y they died off i have many corals and many different types of polyps in my tank already (green button, star, orange, yellow, etc...) and all water parameters are excellent.... the only thing i can figure out is maybe they did not acclimate well to my tank.... maybe the lighting maybe the salinity i dont know....
the reason i say this is because i thought something must have been eating mine too but i dont have anything that would eat them.... mighht be the same case for you.... id watch your tank carefully if u dont see anything actually eating the polyps might be that they are just dying....
good luck

well the water is top notch, 8.2ph, 0 nitrites, and super low nitrates. 445 Ca
I do have an alternate theory now, I notice a brittle star sweeping near them alot, as well not all the zoos are slowly leaving, other colonies are thriving, it's just two or three of them... perhaps a very hungry serpent/brittle star?
My success rate is ....up there. I dont lose things easily (unless it's euphylia lol) so I'm just...baffled for the moment I guess.
Anyone else have a thought?
