Got my first coral and found a critter (Nudibranch?) stuck to the glass right after adding it to my tank, any idea what this is?

I pulled it out and put in in a little jar when I saw it.

Not sure from that pic, but the "arms" look sort of like a serpent star to me. Typically, these animals (which are not true sea stars) have five arms, but they can break them off, and I think they can regrow them. So you may have one of these who has lost an arm or three.

EDIT: and welcome to Reef2Reef!

Looks like some sort of echinoderm to me. I love the little guys. I have some that hang out in little crevices and stick two or three arms out into the water column when the LED sun goes down.

Micro brittle star. Good hitchhiker (although it appears you aren't dipping your corals?)

Yeah, I'll definitely dip future ones, little impatient today tho, do you think it's okay to leave it in there then?
