Worm with no legs and no tentacles?

[avaneaton2000]

I saw a worm in my tank today and can't find it in any of the ID's. Here are the pics I could get:

To give it some scale: about 4" long and a few hairs thick

It has two brown lines that run down it's body, and even under a magnifying glass I couldn't see any legs, it almost seemed like it moved like a snail.

Any ideas? Good or bad?

Thanks

Could be a nemertean worm.

Points to Roman, it is probably a nemertean. Harmless to anything larger than itself and that includes decorative corals and fish.

Thanks! That sounds like it, I saw that article but none of the pictures look like what I have.

Thanks guys!
