Good crab or bad crab??

[dan’s tanks]

Got this little guy In some live rock from Tampa bay saltwater. I’m assuming he’s bad so I isolated him to a cup. I’m pretty sure it’s a gorilla crab, but I just wanted to know if he’s safe to keep.

Looks like a gorilla crab, and yes, it's bad. You don't want it in your tank, but you could always keep it in a sump or separate tank (just beware of them damaging wires).

Agreed. Definitely bad.
