What kind of crab is this?

[Just John]

Wondering what type this is and if it's reef safe.

 

[ChiCity]

nope, not reefsafe

(looks to be a type of gorilla)

 

[ReeferHD]

not a gorilla crab, its a purple porcelain crab and it's 100% safe

Flat claws? + Hairy...

no; it’s a porcelain crab…
i hastily looked at the picture,
but if you look close,
you can see the purple banding…
and the claws match too.

Agree porcelain and while not welcomed in my tanks , not a killer crab

Thanks everyone and I appreciate all the links! It came as a freebie with some gulf live rock I just picked up and I wanted to be sure I wouldn't regret putting it in the tank.

its a filter feeder so its harmless. You just rarely see them as they are flat and hide.

You'll see two 'fans' pop out from infront of it.

"Polyonyx gibbesi, the eastern tube crab, is a species of porcelain crab in the family Porcellanidae. It is found in the western Atlantic Ocean."

I agree it is a porcelain, just trying to nail down which one.

The one OP has is petrolisthes galathinus, you can actually buy them from some suppliers.

Here's another thread of one: https://www.reef2reef.com/threads/porcelain-crab-petrolisthes-galathinus.83587/
