ID Please on neon green worm?

[MantisO_o]

Okay i looked up and saw this long line on my tank glass. I thought the tank cracked then realized it was moving. Its a worm? a slug? ain't superman... what is it? Its a neon green to very light yellow thing. the front end seems to look like Nudibranch kinda, shrugs. Any help would be great.

Very sorry for the tank glass being dirty. Bad reef keeper i know ​

Looks like a ECHIURA worm. Commonly called the spoon worm. Look4 yourself.
