What is this crab on my cucumber?

What kind of crab is on my cucumber? He was a hitchhiker, and I am curious to know if he is ok or not

Calico crab maybe they can get quite large 4-5 inch.

Is a calico crab not good in a reef environment?

The calico crab has red spots, not white. I can't identify the crab but I would watch what he does. If he's eating the cucumber, I'd toss him in the sump. If he's just hanging out, I might leave him. Cool crab either way. I'd take him if shipping was feasible.

I picked him and threw him in the sump. He is a pretty cool looking bugger, still don't know what he is for sure. He doesn't move around too much, but hasn't been there long. Mr X I may be interested in moving him, but I am in MT and I think quite a ways away from you!
