He's kinda cool looking hope I can put him back in the tank, found him in the sump. Might have hitchhiked on some acros I ordered. What do y'all think?

It's not going to live very long but go ahead & put him back, he's harmless. That's an epitoke in the polychaete family Nereididae. At this stage it's not going to eat anything. Epitokes are the sexual reproductive stage. Filled with eggs or sperm the adults swim up from the bottom to release gametes. The spitokes of some species can survive to reproduce again but most nereids can only breed once.
