This afternoon, I've been watching two tiny creatures chase each other around the front pane of glass. They're each about 1/16" long.

After dinner, I returned to the tank and one of them is laying eggs!

Anyone know what these are?

Bristle worms, perhaps? Would they be reproducing at such a young age?

I think you're right. Are they beneficial?

There doesn't seem to be much info available on these guys. Anyone have experience with them? Is there any reason to remove them?

Yup, some species of Ophryotrocha. They're micrograzers. Get a couple hundred or thousand on your glass and they'll help keep it clean. Otherwise they're a minor step up the food chain. :)

Thanks! I'm going to leave them be. They're still in the same spot this morning. They appear to be guarding the eggs.
