Hey guys, was feeding the tank today and noticed this little guy sitting on my rock, any idea what type of crab it is and whether or not I should remove it. It's only about 1cm long. I don't have any other crabs in my tank, at least ones that I know of, lol.

Gall crab?

Gall crab?

Hmm, could be, I'm gonna yank it just in case.

Gall crab?

I would agree that is what it is.
