So, I'm not sure if it actually did or not, but it looks like my emerald crab may have ripped a few of my zoas off their rock... there's little zoa-shapped holes where there once were healthy little corals, and the emerald was sitting next to the frag eating. I thought they only ate algae? How likely do you think it is that the emerald would eat zoas? Just trying to figure if I should take this guy back to the LFS before my corals are decimated....\n\nthanks!!
