? If the water surface does not pass the lamp in the water, you can put the side lamp on the lacing wire to make it shine 45 degrees down evenly. In this way, we can try our best to avoid the phenomenon of falling eyes of arowana. The underwater lamp can also be placed 8 centimeters above the water surface. This can not only provide light, but also play a role in maintaining water temperature. When you turn on the light for the arowana, you need to cover the fish tank in advance, wait for the arowana to adapt to the light slowly, and then remove the things covering the fish tank. Lights should not be turned on for more than 8 hours. Another point that breeders tend to overlook is to avoid turning on the lights suddenly at night. At night, you can cover the fish tank with something to block the light, so that you can turn on the light at any time.
Arowana can recover by itself, but it takes a long time to recover slowly. In fact, the location of the light source is the main reason for the loss of eyes of the arowana. If the light source of the fish tank is too strong or the bottom of the tank reflects light, it will cause the arowana to look down reflexively, which will cause eye loss for a long time. The most effective way to treat their eye loss is to try not to let the arowana look down. If the position of the light will not be discharged, the tank can also be sealed, leaving only a top light, which allows the arowana to recover quickly. Then when feeding, try to choose some food that can float on it to give the dragon rain and reduce the number of times the dragon fish looks down. In this way, the eyes of the arowana will recover in about two months.
