Sea Slug - - Tritonia??? Good or bad?

[MMJ]

I found this in my tank - - must have been in the live rock. I looked in a book I had and it had a very similar picture and identified it as Tritonia. It said that is eats algae and dead cells off of corals, but I'm a little concerned and don't want this thing eating my Xenia (it was hanging around it when I first saw it).[

No idea, but I will give you a free bump so someone else can take a stab at it.....Capo?

The only good sea slug that I'm aware of is a berghia.

All are predators and many are extremely toxic.

If it eats Xenia I want it.

Almost looks like a lettuce nudibranch.
