Little white/grey crab

Drakal · Nov 24, 2021

Hi, saw this guy the other day, but can't catch him. Less than a centimeter at the moment.

Found a mold few days later :

I tried to ID him but can't found something that does really match

Looks bad ?

He's cute - just not sure if he's reef safe (can't ID him).

I am not an expert by any means, but given the black-tip claws, the carapace shape and what looks to be hair in the close up picture of the molt , it maybe in the Xanthidae family; a gorilla crab. My understanding is they are bad news. Any experts out there that can verify this?

Everything looks fine, just a perpermint shrimp is acting weird (slow/not reactive) since few days.
