Unknown Sea Slug

[TheOtherDay]

I've seen pictures of this before but I forget where and what was said about it. It hangs out on my Star polyp at night, Never around during the day. What is it? Good/Bad ?

Makes me nervous that it hangs out there.

Sorry for the pictures, my camera stinks, and is even worse at night (hence the flashlight).

It appears to be white, no markings or anything.

It has now been removed from the Polyp.. Did I do the right thing?

Yeah. Judging by the morphology and behavior you describe, he sounds like he was eating them.

See if you can find it on seaslugforum.net.

That looks like some anemones I have in my tank, when i first added rock I saw about 3 of these, they looks like slugs because they were kind of scrunched up, now I've got tons of them in my refugium and when they are all spread out you can see they are little anemones, they get to be about 1/4 - 1/3 of an inch in diameter then split. They dont seem to be harming anything in my tank and since I added peppermint shrimp i hardly see them in the main tank. Don't know of this is the same thing the pics are kinda blurry.

Heres what mine look like.
