black worms in coral QT

[ruth howard]

Hi everyone, my coral QT exploded with these tiny black worms. All corals had been dipped in Bayer and CoralRx. The only items in the QT are corals and a piece of egg crate. Does anyone know if I need to be concerned with these things or are they okay? Does anyone know what they are? Thanks

That's Dorvilleidae and more specifically it's probably an Ophryotrocha generic complex. They have the planaria shaped heads you see in that first picture.

Thanks Lionfish Lair, they are so small, I thought it might be dust. Are they safe? The QT is 10 gallons and I don't have any fish or CUC in it.
