1. Change 1/3 of the water every day and pay attention to the temperature difference of the water. The new water should be 1-2℃ higher than the water temperature in the tank.

2. The salt concentration is generally 300 grams of salt per 100 liters of water, and salt should be continuously added as the water is changed every day.

3. Slowly raise the water temperature in the tank to above 30°C. Observe the condition of the dragon fish from time to time, and generally the effect will be seen within a week.

Generally speaking, even high-quality arowanas can experience eye loss. We should prevent eye loss as much as possible. First of all, we should not keep the arowana in a tank that is too deep, so that the arowana will not lose its eyes due to long-term searching for fish food at the bottom of the tank. Secondly, we should pay attention to the lighting, choose the intensity of the light reasonably, and try to reduce the stimulation of strong light to the arowana's eyes. You can add a lamp on the innermost part of the upper part of the fish tank. Just like the original poster thought, do not choose too bright brightness, and keep the light intensity in the tank consistent. This will help reduce the fatigue of the arowana's visual adjustment function, which is very helpful for preventing eye loss.
