A few weeks ago I started my very first shrimp tank. I started noticing a bunch of small white dandelion looking growths all over the glass and filter of my tank. They're so small you can hardly see them with your eyes unless you're looking very closely. They're attached by a small filiment, and extend into a white parashoot/dandelion fluff that moves in the waters current. There is thousands of them. I redid my tanks substrate (due to having way too much) and decided to take that time to rub it all off. A few days after getting everything set back up, they're back. My amanos and red cherries
