Anyone know what this worm is?

I’ve been watching this worm grow over the last several months. I am not sure what it is, the tube is soft and telescopes multiple times. The tip looks like a feather duster when extended. Super sensitive to sound and will retract like lightening!

I'm no expert on worms, but the thing I found looking up in the Hitchhiker list on Lionfish Lair that looks the closest to yours is a peanut worm.
