Need An Id On A Slug / Worm Thing I Found In My Aquarium:

[voycey]

it is about an inch long - i found it in my sump the other day, sorry the picture isnt too clear - it has red diamond shape markings on its back and the underside is similar to that of a slug's!!

Shape looks like a peanut worm, but I've never seen a peanut worm with those colors

hey, cheers for the reply - its not a peanut worm

any other ideas?
