I found this little guy in my live rock, and he seems to be some type of Eunice worm. He also seemed to build his own lair, kinda like a spinoid worm. Also, it doesn’t seem to be an ambush predator like a bobbit worm- it just munches on the area around it like a caterpillar. Should I try to trap it or is it not one of the predatory Eunice worms?
