reef safe?

I'm not sure what family...maybe Grapsidae or something similar. Definitely not the zebra crab (Zebrida adamsi) which is an obligate commensal on urchins. Whatever it is it's not one of the few truely reef safe crabs like porcellanids. It will be an opportunistic feeder able to scavenge, eat detritus, or prey on other critters - whatever's available. A good candidate for your sump.
