Tiny curly white things on glass

[DedElvis]

Hi all - I think I know what these are, but they are multiplying daily! Very tiny white "C" shaped things growing on glass, wavemaker, rock, everywhere. My phone is a potato - cant take a good pic (worthy of posting anyway)

Tank 2-3 months into cycling. Livestock added 2 clowns, zoa/paly frags, and a few chips of rock from LFS. Every day 5-10 more of the tiny circular growths.

Spirorbids worm is what your looking at, those guys are good for your tank. It’s an indication that your tank is has a lot of nutrients. They have covered all my glass, rocks, Powerhead and sump. These guys come and go. if you cut back your feeding. Their population drops dramatically.
