1. What is the reason why Arowana drops its eyes 1. The light is too strong: Arowana drops its eyes probably because the light in the upper layer is too strong. Although they have phototaxis, they also have light avoidance. Arowana, in particular, is sensitive to light. If the light in the upper layer is too strong, they will look down and avoid it.
2. Too much sinking feed: Arowana may lose its eyes because of long-term feeding of sinking feed. If they have been foraging at the bottom, they will also lose their eyes.
2. How to correct the slight eye drop of Arowana1. Feeding floating feed: Arowana can try to feed floating feed to correct the slight eye drop of Arowana. If the fed feed cannot float, it can be tied on the water surface with clips or fishing lines to attract Arowana to forage on the upper layer. After the arowana is used to foraging in the upper layer, its eyes will recover.
2. Install upper lamp: Arowana can also try to install a small lamp at the top of the fish tank to correct slight eye drop. Arowana has certain phototaxis. If the breeder turns off all the lights, leaving only one small lamp on the upper floor, they will keep looking up. But the brightness of the light should not be too strong.
3. Reduce high-fat diet: Slight eye loss of arowana can also reduce the feeding of high-fat food, because too much fat can also cause eye loss of arowana.
4. Lower the water level: Breeders can also adjust the water level to 15-20 cm below the fish tank, because this will improve their sight and correct the dropping eyes of arowana.
