Looks like a molt of a green emerald crab. Didn’t know I had one in my tank either. If it is, definitely beneficial for any hair algae, but could be dangerous for any ornamental shrimp.

Doesn’t look like a emerald to me. Might be but might be a gorilla crab or .....?

Definitely not an emerald. That guy has sharp claws, emeralds have spoon shaped claws.
Looks like a gorilla - so sump it.

I have a similar one. Don't think it's an emerald. From my research appears to be a type of bristly crab. Been keeping an eye on it and so far shows no interest in fish or corals. Has been quite elusive but if I can get him I’d sump him just to be safe.

Agree. Sump it and observe.
