Is it my emerald crab?

[Bougie]

I know there's lots of posts on do emerald crabs eat zoas. Sounds hit or miss. I have 3 zoa frags. Just got an emerald crab and a purple dottyback. Ever since the zoas have looked like crap. The frags weren't glued down well and I keep finding them on the bottom of the tank and I have to pick them back up. Now one looks like it got part of it eaten. Is it the emerald crab? I also have 2 clownfish, 1 diamond goby, 4 hermit crabs, 1000 snails

Hard to say for sure unless you catch them in the act. Crabs in general for me have always been hit or miss. In my current tank I have removed all hermits and emeralds as I find they do more harm than good.

I have never had a emerald mess with my zoas other than walking on them just keep a eye on the. Check ur tank at night time

Well I caught the SOB (emerald crab) in the act. He wasn't eating the zoas per se, but he was aggressively picking around them and kind of squeezing the polyps. So I think he has to go :_(

Ive had emeralds eat zoas. I usually find them dead on the zoa…
