Is this a bad hitchhiker

I was checking out my GBT that has been hanging out in the back of my tank and I saw this:eek: at first I thought it was my sea serpent , but no that not him. Sorry about the pictures, not so hot. It's about 1.5 - 2 inches. Thanks.

Could it just be a bristleworm. It's OK, if it is.

I kind of thought that I just needed reassurance :D thanks.
