Please to meet you, hope you guess my name! Sorry I couldn't help myself.

(Hard to see they're tiny)

So i have a few of these guys on the glass of my fuge, the closest ID i could find is Nereid worm. I haven't seen any in my DT but I'm sure it's only a matter of time if they aren't in there already. Does anyone else have them in their tanks? And more importantly are they reef safe? Thanks for any help.
