what's eating my zoa's?

[link81]

just stopped at a lfs on wednesday. picked up a tiny frag of zoa's. neat little redish ones. maybe 6-8 polyps.
looked good. all opened up nicely within an hour or so.
everyone was leaving them alone.
Looked at the tank the next morning and i'll be darned if there weren't a few clean circles on the frag plug.
thought it might possibly be the hermit, i saw him messing around with some other stuff, so into the sump he went.
this morning..... well no kidding. the entire frag plug is picked clean.......

tank is a 40B, 2 emerald crabs, fire fish, six line, 2 clowns, pistol shrimp and watchman goby.
handful of random CUC snails from reefcleaners

Could be emeralds or hermits. Probably not nudi’s because you have a sixline.

no hermits, the only one i had got banished the day before.
i'll watch the emeralds, one or both might get banished as well. they can much on chaeto all they want and re-join the display when there's stuff for them to eat.

stupid crabs lol
