Possible flatworm? Need ID

[JosephM]

I fed my frozen food and then reef roids and this bugger was just out swimming in the open. My clowns took interest and were chasing it but I didn’t wanna risk anything and scooped it out. Super nasty, maybe about 3/4” in length

Definitely not a flatworm.

Yeah lol, did some digging and realized that but through all the digging I couldn't find what it is either

he is an epitoke of some sort of polychaete, the main worm could be living in the tank as a peaceful scavenger, and this was either him or his sexually active clone enjoying a relaxing swim before being scooped

Is he a good guy or bad guy? Do I need to be worried about lots of reproducing. And the sexually active wormy has been given to the crapper.

good guy, don't be worried, you may see them swimming every couple months or so

also many can bud off new worms from their backside so they reproduce anyway

I’m assuming they’re just detrivores? Kinda the same deal as bristleworms... nasty but have their place in a tank

yeah there is very few actually destructive polychaetes that survive the voyage to our aquariums
