Little worm/centepede like critter

[jy808]

Woke up to get some water and saw this little thing wriggling around in open water.

I had only just put 3 snails in 2 hours ago, so hope it isn't from the snails.

I've yanked it out with a net to have a closer look what it was.

Looks like a bristle worm to me. They have had a notorious past but IMO they are good tank critters.

Yes, a bristle worm in epitoky.
