I have a ferly new planted tank. Iv bean slowly adding to it since Christmas I have a few plants, a snail, a african dwarf frog, and a baby koi that I'm growing to put in a pond this summer. The tank has 0 amonia, 0 nitrate, and verry little nitrite. The water levels were kinds bad for a little bit and I just got them were im comfortable. Everything seams fine but my african dwarf frogs eyes are clowdy, like kinda bad. He's eating fine and doesn't seam sick and I don't know what's wrong. For a bit I thought it would go away after he sheds bud he shedded last week and it's not better. I tryed melafix for a week and it seams it might have helped a little but not much. Dose anyone have any thoughts or ideas?
