Crab ID?

He’s about the size of a dime and has only 1 claw. Hitched a ride on some live rock.
Good or bad?

it looks like it could be a pithos crab, which would be a good guy, but I am not a crab expert.

I am also not a crab expert but I think it helps if you can get a picture from the top

I've not had good luck with reef safe crabs. All of mine still nibbled on things causing me to re-home them.

He's a cute bugger.

Unless you know the species of the crab when you buy it, 9 out of 10 any crab has the potential to be a bad crab. Put it in the fuge

I tried but photo wouldn’t turn out.

It was a hitchhiker. 3rd one I’ve found from live rock.
I got a decorator crab, whatever this is and I’m pretty sure the other one is bad because it had black claws. I put him in a QT tank.
