ID a crab

Hi Guys,

Can you help me to id this little ugly hitchhiker. Someone was eating my zoas one by one and I suspect this guy. (I had 2 of them coming with live rocks). Both are in the sump now, but wanted to check if anyone can identify it. (first time see a crab like this).

Looks sort of like a decorator crab. If so I dont think hes your culprit. @KJ

Cool, thanks! I did some research and it looks like a one called as spider decorator crab. It’s definitely not reef safe as people had it eating recordeas. I do still suspect he is a culprit. I will put my colony with 2 remaining zoas (used to have 15 :-( ) back and see how it goes.
