weird looking critter

[Maxi]

I have some new little thing in my tank that just appeared today. theres a bunch of them. There is currently nothing in the tank but live rock and diatoms, and some hair algea. I drew the things because I couldn't get a shot of them. What are they? They look exactly like that in the picture, except their bodies go more like a teardrop. Really small.

What is it?

Those are good critters.

pod of some sort

great picture. normally when people want ids they just send a really really fuzzy picture that could be anything from a gem tang to a nudibranch you def have some pods (cope- or amphi-) both are good. if it is really really big, then I don't know

the drawing kind of looks like a pineapple sponge, but I assume these critters are mobile, right? if so, likely a pod of some sort.
