I have a tank with 1 African Clawed Frog, and 2 ghost shrimp. They are there mostly for cleaning, and a late night snack for froggy. Recently there are about a thousand little white puffs floating around the tank. It almost looks like cotton fibers in little groups. They are stuck in the filter, and on the caves, and on the rocks, and everywhere! What are these little white things. I read online that ghost shrimp keep their eggs close to them and they are green, so I don't think they are eggs. But I could be wrong... HELP!
