I currently have a 10 gallon planted tank that's been running since June. It house 7 Celestial Pearl Danios, 1 Assassin Snail, and 2 Amano Shrimps. The tank recently became cloudy, I have no idea why. I've tested the water and everything is perfectly fine. So I was wondering why it's cloudy and if I should do a water change or just leave it be.
