What type of crab is this?

Found this guy on one of my acropora corals. Wasn't sure if he was good or bad, but I got him out and wanted to check if he's ok to have in the aquarium or not.

Thanks,
Nate

Yup, acro crab
If you dont want it, I have plenty of acro's for him!

Looks like he came out of the aculeus from the Grab bag - put him back into that acro ASAP

cute little guy. i would have thought fiddler because of the bigger claw but since you said it was in an acro it narrows things down.
