What is this alien?

[Snotdoc]

I have several of these. What are they? About half a centimeter. Always waving their little antenna things. These seem to clean the reef?

Nudi? A type of slug maybe? Not 100% sure....looks interesting though

Looks like a Porcelain crab, if it is, they're harmless filter feeders.

Defanitly porcelain crab. Very cool. And harmless. Looks like the more attractive kind to. There are also green/grey ones that are not as pretty.

It looks like he's got nice moves, dancing to the music lol

Does it move around? If it's attached to the rock it might be some sort of barnacle.

It's a Caribbean porcelain crab. I have three in my tank as well as the standard anenome crab. They all will fight if they get close but usually back up to some random spot and don't move around much.
