Hermit Crab ID

[daisytrail]

While picking up a cleaner crew today, this little guy hitchhiked by hiding in a turbo snail shell. He's fuzzy, cream, and has bright blue eye stalks and facial parts. He's about the size of a thumb nail. I was wondering if he would be worth it to keep (I got him for $4 it would seem) or if I should toss him. If kept, his tank mates would be two fairly large clownfish and a purple stripe dottyback (along with my intended purchase of turbo snails and some astrea snails). There is also some soft corals in the tank.
Thanks for any help!

If he is very hairy, he is most likely a hairy hermit crab, although it is hard to tell by your picture. They get big and can be a problem.
