I bought four of them today from the LFS, they are smalllllll, I would say 1/2 inch or a tad bigger. They should make it, if they learn to stay out of the Rose Ann. and the Coral banded dosn't eat them. I wanted to buy a frag of zoas or something, but the LFS isn't worth squat and they carry nothing, feel lucky if your LFS carries anything at all.
