The three reasons for eye drop mentioned above inĪre generally due to the "shameness" and "phototaxis" of arowana. Therefore, when the position of the lights in the water is not correct, the arowana will look down in order to avoid the strong light that stimulates the line of sight. In order to stimulate the color of the dragon fish, the light in the water is usually strong. At this moment when the light changes, the dragon fish will look down, and it will lose its eyes over time. What does the light source change too much? That is, the light suddenly becomes brighter or darker suddenly, such as suddenly turning off or turning on the fish tank lamps in the dark. If the light in the tank cannot be brighter than the indoor light, you can add curtains to block the light outside the tank. This is why it is best not to place the fish tank on a well-lit balcony. No matter whether the lights in the tank are turned on or not, as long as the light outside the tank is obvious If it is bright in the tank, the arowana will swim sideways, and it will lose its eyes when it swims sideways for a long time. The brightness in the tank is lower than the outside of the tank In addition to genes, there are three main reasons that cause Arowana’s eyes to drop: An arowana with a lack of perception can easily cause the breeder to lose his interest in viewing, and it is also easy to be discouraged and lose the desire to breed. Although losing eyes is not a disease and will not threaten the health of arowanas, if a good-looking arowana has a pair of droopy eyelids and drowsy, it will feel unconscious. Recently mentioned in the aquarium exchange group how to adjust the dragon fish's eyes.
