box crab or shamefaced crab? I'm not exactly sure which calappa it is but, it sure does look like one.
hth and I might be wrong.
 
thanks for pointing me in direction, god there is a lot of species. anyone else?
 
Fwiw, if it is one of them they tend to be aggresive and will eat your fish etc. It might also be a shore crab. So, I'd say if you've had a it a while and it hasn't hurt anything keep it If, it's a new intro or if anything is MIA well....... bisque anyone?
 
its a friends, and its been eating some corals, he stayed up to catch it at night. not sure if he killed it or through it to the sump
