I think he is a flower crab but not sure? little help?

More commonly known as a shame faced crabs, will eat any fish or motile invert it can catch, digs so may tumble rock work, and I've seen them eating feather dusters in the ocean while diving, so I wouldn't keep it with anything it can hurt.

neat! i'd let him live in my sump. my display, not so much...

Awesome looking crab though. Not your normal "gorilla". I once had a rough box crab that was awesome. he also ate everything.
