Bunch of boogers (slug)

[reefbabe]

A week ago, I noticed some new sea slugs in the tank. Now...there are about a hundred of them (that I can see). They seem to be herbivore because they are hanging out on the backside of the aquarium. They look like the things that my 4 yr old pull out of his nose (BOOGERS) and move like an inch worm. Does anyone have any ideas on the ID?

Sounds like (and looks like in the one picture) stomatella varia. Harmless algae grazer and known to reproduce in the home aquarium.

Keep an eye on that thing. You might have a nice nudi that eats algae. It looks like a sea hare in some pictures. Probably not though.
