My brother found this in his tank, can anyone confirm if it is a peanut worm, or if it isnt, does anyone know what it is? Thanks in advance.

90% certain it's cryptoplax larvaeformis from the link above.

Awsome, thanks guys for your speedy responses and great links. I'll be sure my brother (coreyskylar) checks it out.

Thanks for the link. We have a couple of stomatellas in our new 10g that pretty much only come out at night.
