I'd this crab please

[Dodgy Russian]

It has hairy legs and a smooth rounded carapace.

I got it from the lfs as a freebie for my clown trigger to eat

I don't know if the crab will be reefsafe or not if not it's trigger dinner

 

[MikeandNicole]

Not reef safe.

Looks like a mithrax to me.

Should be an Chlorodiella nigra. A very harmless (mainly) algae eater.

That crab just ate half of my orange cycloseris tenuis. The crab can now dine with my triggerfish. Do you think the cycloseris could recover with half it's skeleton exposed, will it produce babies on the dead half?
