Inch long, lime green worm?

Thoughts on this bright green worm guy? KP liverock from florida. Seen him tooling around a few times now.

some nemerteans move as such when is the most recent tank addition?

 

[MayoTheCondiment]

Tanks about 30 days old - this guy came in on the live rock which was first thing in tank; haven’t added anything else to tank except pair of clownfish and a handful of cerith / nerite snails

Looks like a peanut worm but need more of a close-up.

very possibly a type of nemertea with how the head moves, most are predators feasting on various crustaceans, marine worms, and clams, as for the scavengers they tend to have big big nostril looking slits on their faces and will eat dead prey quite readily. Scavengers are usually pretty welcome, the predators are iffy, some can eat slow enough to never be an issue, some may eat every polychaete until they themselves starve. the predators hunt with a venomous barb and can therefore subdue worms or crustaceans more than twice their own size

predators tend not to eat much that is already dead, they like to hunt with that barb
