One of my neon tetras has been sick the last 9 days or so. He has lost all of his colour and has not been eating. He has still been swimming around, but today he has been swimming vertically to the top of the water and then falling back to the bottom where he lies for a few seconds before swimming around again. As of now, he is lying on the bottom of a float tank. He is still breathing, but won't last much longer. All other tetras are fine. Still have their colour and are still eating. What could have caused him to loose all of his colour?
