I have a danio that is 'floating' at the surface. It can hardly swim below the surface of the water. When it stops swimming he floats back to the surface. I have always noticed the danio hanging around the surface of the water, but never this bad. The danio is 'floating' so badly that you can see the top of his body break the surface. Is there anything that I can do? What can be done to prevent the other danio from 'catching' this? Anything would help!!
