Filter feeding crab

[Malolo]

This guy is the coolest hitchhiker I've ever picked-up. So far, he has been completely well-mannered, but his large claws give me pause. I think he could do some serious damage if he was of a mind to do so.

Anyone familiar with this guy? His carapace is about 2.5" wide and growing. I could catch and pull him if I had to, but I would really like to keep him. He's in a large mixed corals system with tons of LR and quite a few fish. He has about doubled in size in the 3 monthes or so I've been tracking him.[

Did you get FL live rock? They are Petrolisthes galathinus, aka Porcelain crabs. I love them!

I had an anemone crab (they filter feed too). Here is a pic of him

Nice crab! Keep him! He shouldn't bother anything.

Yep, lots of people pay good money for those guys! Keep him.

Actually, I'm pretty sure he came in on Fiji LR. There is no Florida LR in the system.

I'm pretty sure this is not an Atlantic critter. Can anyone else confirm his ID?

Looks exactly like a Porcelain crab to me.
