Crab cleaning himself?

[HermitGuy3]

Hello! I just wanted to post about this because it seemed so cute! So my new crab Fizban limes to climb into his water dish and just kinda walk around in it. And tonight I was watching him in his water dish when he started to clean himself I think?( that is what it looked like) it kinda looked like he was rubbing his one leg against his claw/ other leg while in the dish! Then he proceeded to use one of his appendages ( idk what they ate called, maybe I should look at crab anatomy lol) near the antennae to wipe if his eye! It looked super cute and unfortunately wasn't able to get pictures. Sorry if this is the wrong forum! It just seemed right because of the "crab behavior". I was wondering, has anybody else seen their hermits do this?
