What is this crab?

[cohojoe412]

One of my Acro has looked a little off and noticed this crawling on it. Looks like some sort of a crab, can anyone ID it?

I pulled the acro out and have dipped it incase there are more, I can’t see anything else on it

Looks like a gorilla crab to me (not Reef safe). Let's see what the smart people say....

Hard to say for sure from the pic, but possibly the Hairy Coral Crab, Cymo andreossyi?

If so, they're somewhat parasitic on their host corals; in small numbers on big colonies, they're helpful, but in large numbers and/or on small colonies, they may kill the colony.

Probably Cymo andreossyi - generally not one you'd want in an aquarium, but at least somewhat beneficial in the wild:

I am leaning more toward Decorator Crab....

Looks like that to me too but @ISpeakForTheSeas is probably right
The crab is kinda cute though

I thought gorilla for sure… but a baby decorator? Gotta give u props on that one… I totally agree.
