Hi, I didn't put them there, there are now two of them. It's possible they came as minuscule babies in either a copepod packet, or with some chaeto. Seeing as the chaeto came from a reliable source, im guessing not from them.
Should I get rid or leave them alone?

Defo a slug of some type, it moves blooming fast when it thinks it's going to get caught, you can just make out in the photo two sort of antenna on it. The top of the body is a lightly mottled brown colour

Looks like a stomatella?

Just googled that @mightyhatter , and of course you're right!
 I'm happy to not remove them, and that in fact they're valuable additions to CUC.
They must have come in the chaeto at a miniscule size.
Happy to leave them in the sump.

Ah I thought that was a bit of chaeto! You lucked out, they are good CUC!
