Just an aquatic annelid. No threat to your fish.

So long as it's nothing harmful, that's pretty cool. How long has that tank been running?

It's funny how well established tanks after a while become a live body of water and an ecosystem, haha.

Is it fish poop LOL? My fish have been eating red pellets lately and that's exactly what their poop looks like.
