What is this? A Nudibranch?

Just saw this purple thing on my glass as we were cleaning the tank. Any ideas what it is and whether it is ok to keep in the tank?

Looks like some sort of Nudibranch or snail to me. No clue where it came from!

looks like nudibranch to me, and a pretty one, too. Have you had any mysterious coral tissue death or regression? If so, it's probably your culprit.

I just took it out and it looks more like a snail on closer inspection (it has a shell). I put it in a QT tank that is full of wrasses so let's see how long it lasts!

Any chance of a pick of the "shell side"? Looks pretty cool.

 

[whippetguy]

wow, if that's a stomatella snail, I'd like some for my tank for sure.

Very very cool HH

Stomatella, confirmed. Unusal colored one. I have dozens in my tanks. WHen my snail poplation gets low, these guys multiply rapidly. I think they do a better job too. I only keep a few turbos, just to ensure clean glass.
