ID please - worm like

[rpeters]

Can someone help ID these? Had a mesh filter sock on which these guys came from, in a bucket they are black and visable when looking close enough

Dorvilleidae.

Dorvilleidae

So searching and watching videos I'm not seeing the "legs" under the microscope and it appears Dorvilleidae walk vs slither which these appear to do. is that related to age?
Also is there a database of pics and IDs of things? new to all of this and just got a microscope so curiosity is getting the best of me

This video any better? Im not seeing the legs or the movement i see in other Dorvilleidae videos

So decided to run a magnum polisher for about 18 hours with some diatomaceous earth to clear up the water a bit and below is the filter. you can see all the black things on the filter which are the same as above. I continue to look at them and as mentioned above dont see any legs and their movement isnt like any videos i have seen for bristle worms. @KJ #Reefsquad do you still think this is Dorvilleidae? The polisher was attached to side glass so was kinda surprised to see so many as I would have thought these would remain more in sand bed or in rocks. I dont notice them in the water either

They look very much like black worms (blood worms). Have you ever fed your fish black worms? Sometimes excess feeding will allow survivors to take up residence in the rock or substrate, where they can flourish if conditions are right. Other than that, I have no idea. There are 1000's of different marine worm species, so narrowing it can be very difficult. They look benign, but then, so did my ex-wife.

I have feed blood worms but only frozen as well as rods food but never any live ones. I dipped a filter sock in my water column and got some so the water appears to be full of them. Also not sure if that what causes my water to appear cloudy. Just now more curious what they are and how they got here
