Friend, Foe, Cucumber?

Can anyone ID this for me please? I wouldn’t have seen it if it weren’t for the stringy substance it was emitting.

Guessing it may be a peanut worm from a picture I found on the what is that thread.

You are correct, it is a peanut worm. It should be harmless, even if a little weird looking.

Thanks. I put him back in the tank and he went off to do whatever peanut worms do.
