Weird Worm Thing? Help!!

[TheFruitGoon]

Hey guys! My friend found this weird critter in their tank and we have no idea what to ID it as. Looks like some type of worm. Unfortunately there’s no pics of it in the water but I’ll attach a couple of pictures from outside of the tank. The spikes along it move almost like an urchins spikes.

Are you able to place it in a container of tank water and snap a picture? Marine invertebrates loose a lot of their form outside the water.

+1, and a paper towel only adds to that.

it looks like a feather duster worm used to have one, years ago. when it died it lost its feather and looked like this.

+1. Whatever it is, it’s definitely a polychaete worm of which thousands of species exist (ex. common bristleworms, fireworms, feather dusters, fan worms, Eunice, hair and spaghetti worms, and many, many others).

Unfortunately no, in the water it looked similar but it was a bit more red under the lights.
