Porcelain crab doing the backstroke

Last night I saw something swimming around my tank in the dark and then discovered it was a porcelain crab. I had no idea these could swim like that. It wasn’t just fluttering above the sand. It was literally cruising around about 6 inches up. I’m guessing something spooked it.

I’m no crab expert by any means but I do know there are true swimming crabs. I always thought that porcelain crabs weren’t actually true crabs, they belong to the squat lobster family, I know lobsters can swim along with shrimps etc? So maybe they do swim around. Pretty cool if you ask me. Can you get a video of it?

I’ll definitely try to get video if I see it again.
