I recently bought my first discus from a KL shop. One of them has milky or cloudy eyes, one worse than the other. It is only young, about 1″ head to root of tail, and seems to be able to see okay. Have I just bought a bad fish or is this likely to be transit damage that will heal? I didn’t notice this problem when selecting in the shop.
This is bacteria infection.
Apply acriflavine solution plus salt.
Water change and repeat the treatment for a few days.
We do not sell 1″ fish. It is too difficult to take care.
We sell at least 2″ fish. This is the best size to buy.
