nudibranchs, they are feeding on the feather dusters worms like I know they don't touch anything else

 

[DukeReef]

Nudibranchs, herbivores. Should be OK.

Vayssierea sp. - Neat little sea slug

I caught this guy this morning. I thought it was a nudibrach and was going to post and ID but I was able to find it rather easily via r2r search. Surprised I have never encountered these guys before. Since apparently the eat tube worms I put him back. Just thought I'd share a video and photos.

Vayssierea felis, I believe. One of the few kinds of good sea slugs. You’ve got quite a few there! I’d take some off your hands for a small fee if you wanted, jsyk if you want to rid them for whatever reason

 

[DukeReef]

i would love to share them for free but im living Toronto Canada

Wrong ID this is Elysia sp not a Vayssierea sp.

Sorry, it's my fault then.
I don't saw the parapodia on the OP photos, and because of the colours I see (Elysia SP - Green/ish, Vayssierea - Orange) , I make it wrong. I don't see any photo from the side of it, and now probably you figure it out by the darker lines on it, I don't look at them.
And reading about, Elysia is reef safe algae grazer.
