There are some small white particles that are moving around in my fish tank. I turned off my filter to prevent current, and let my water sit still. I can clearly see these small little particles moving in the surface of my water, even when there's absolutely no current in the water. It is not normal movement, they move around in circles back and forth like if they were living things.
They are very small, and sometimes these particles join together to create a big white patch in my fish tanks water. These are like colonies in my water, I'm 100% sure that they are living.
What am i dealing with here? Will it kill my Betta? How do i get rid of it?
