These are all over my glass, powerhead, LR, heater, just not fish - - are these the copepods that I've been reding about? Most of the other pics look more like bugs than these. These more like tiny white worms rolled up.they don't move
You can just clean your glass with your magnet to clear them off, I just got a huge outbreak of them after 1 1/2 yrs. After this initial burst, things have slowed down. I did keep a few just to see how big they may get. Like said harmless, sign of a healthy tank
