Found some worms in my tank. ID?

See the attached pictures. Does anyone have any idea as to what they are? Should I throw them in with my scud culture to see if I can grow them up?

I circled two of worms and tried to draw an arrow to a scud for scale.

Very hard to tell what they are based on the pic -- they're not quite in focus.

I’ll try to get a better picture and post it tomorrow.
