The spiral swimming is a trait of blackworms.

Black worms are oligochaet annelids. That worm wasn't segmented. Its not an annelid. Its a round worm.

My tank is 170g bare bottom. I guess I'll need to clean the filters more often. Stocking is 1 17" arowana, 7 dats from 6-8", 1 5" flag tail, and 1 7-8" sting ray.
