ID a crab

[ecybers777]

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 like a decorator crab.

It looks like a type of spider crab to me.
