Nudibranch?? ID?

[travisr100]

Are these nudibranch? If so, any idea what kind? I found these on my glass right after the lights came on this morning. Get rid of them?

Looks like Thuridilla sp.

[Calappidae]

I forget the name..

but I'm pretty confident on saying these guys are NOT reef safe. Coral predators.

Yup, they're both arminid nudibranchs, probably Dermatobranchus species that feed on soft corals. At least one of those two is a common hitchhiker on "Clove Polyps." They may be color variants of the same species, though.
