Emerald crab eating zoas???

I saw my emerald crab eating a new frag of blue zoas today and had to scare him off. Is this normal?

Yeah, I thought it was really weird. But he was pulling off the tentacles of the zoas. Getting kind of worried. I've also noticed that this guy eats the tubes of the feather dusters in the tank. He doesn't eat the worm itself but all the tubes that the feather dusters live in are totally wiped out.

I thought I heard before that it's rare for them to pick corals, but that some will. Might want to look into taking it back to the store if you can.

Is your tank new or has it been set up for a long time?? I've read that it isn't out of the ordinary for them to pick at zoes and other small corals if they don't have a sufficient amount of algae to feed on. This could be the problem or maybe u just go one that has expensive taste. lol

Yes you`ll need to get rid of him. Maybe put in sump if you have one or trade him back to the LFS. IMO once a coral muncher always a coral muncher. Next time you see him take the oppurtunity to grab him. They are not that fast.

Yeah, it's a relatively new tank. It's been up and running for about 3 months now. Ok...I'll keep an eye on him but if I see him munching on coral again, I'll take him back. Too bad because I really like the guy. He's got a lot of personality. I actually thought I had killed him accidentally by crushing him. But in the end, it was just his molted exoskeleton that I crushed.

Sounds like the tank might be a little too new and lack enough food for him. You can try using a rubber band to fasten an algae sheet to a small peice of rock and put it somewhere alway from the zoas and he should go and much on that. It will supplement his diet from anything that might be missing in the tank and distract him from munching ur coral.
