Worm ID from Australian live rock

[Acroporaaddict]

Just siphoned two of these out of my reborn media substrate. All corals were dipped so must have came from the Australian live rock. Any ideas on ID?

I don't know the exact id, and nice pictures. But it is a predator worm. Do not add to the tank.

Great, they were already in the tank... found them while siphoning the substrate

Antennae on its head point to it likely being predatory, probably not towards fish or larger organisms than itself. This is not a Eunice worm since members of that genus have five antennae/tentacles on their head, and this one only has 3.

There are definitely 5 looking at it, the 2 shorter ones dont show up well in the picture

Zooming in I can sort of see them, could be Eunice then.

Assuming i dont want them in my tank? I got 2 out siphoning 5g from my coarse substrate. This is the first time ive found any type of worm doing 5g weekly for 10 months. 75g system (36x24 fwiw)

I'd remove all that you can find. Probably don't want them around, some eunice can get huge.
