I am stumped. I have a myriad of white dots about the size of a pencil point on the walls and live rock. Fish and inverts are fine and my water is great. any ideas? i would send a picture but they are just 'dots'
Look harder and you'll see them crawl around. They are small crustaceans called copepods. They eat algae and fish eat them. Very beneficial to have in your aquarium.
