Mini Shai-Hulud sand worm?

Am I growing a monster in my tank?

Fell out of a sand tube I dug up think I was grabbing my conch to move him. Was a thick sand tube. Nabbed this guy thinking it might be a eunice, but definitely not. Put him back in the tank.

That’s really cool: appears to be processing the sand like a sea cucumber would. Could be a sandworm though. Better pick up the Hanna ULR melange test kit to be on the safe side though.
