Goes well with his eyes!
very cool guy !

Very cool, I've never seen one before so thanks for sharing :biggrin:

Yup we had some in awhile back.....very neat relationship indeed......the shell is actually harder to take of than the crab.....very difficult to keep them in a reef tank, as they get hung up and trapped quite easily, probably would make a better addition to a fuge.....great pic!

Thanks all, he sure is cool.

I've had him for about a month now. In all honesty, I have never once seen him on the rock. He hangs out strictly on the sand, picking away at it.... and seems to prefer one corner of the tank. Although I haven't observed him at night (so who knows what he gets up to!?).

I definitely considered the difficulty level of the coral when purchasing this guy. If I didn't have bryozoans growing already on my live rock I might not have got him. But if my rock can sustain this coral (or a very similar one) already I figured I could give it a shot :D. It is a filter feeder so zooplankton helps. :) If the coral doesn't survive apparently the crab can find a new home in a shell.

I'm pretty impressed with him, but I agree it is not something everyone should try, and for sure not something aquarium stores should bring in frequently.
