Manlongyu should be oxygenated, but not for a long time. Generally, oxygen can be used for about an hour a day. However, in rainy days, they need to play for a while, when the oxygen content in the water is very low, long-term hypoxia will cause them to suffocate and die. Whether aquatic plants are planted in the fish tank should be analyzed according to certain conditions. If the fish tank is big enough, you can plant more. If the fish tank is small, it is better not to plant it.
1. the arowana
needs oxygen. Oxygen is necessary for the survival of the arowana, but the amount of dissolved oxygen in the fish tank is limited. Once the oxygen in the fish tank is insufficient, it will affect their survival. Generally, when they eat or rainy days, the oxygen content in the fish tank will be relatively low, at this time, they need to add oxygen to the fish tank.
If there is a small amount of lack of oxygen in the fish tank, it will cause the phenomenon of Manlongyu jumping into the tank. If there is a large amount of oxygen in the tank, it will cause the fish to suffocate. Normally, they are given oxygen for about an hour a day, but in rainy days, they need to be given oxygen for about two hours a day to meet their daily needs.
If the volume of the fish tank is relatively large, then some aquatic plants can be planted in the fish tank. During the day, aquatic plants can carry out photosynthesis, provide oxygen to the fish tank, and can play a decorative effect. But if the fish tank is too small, it is better not to plant aquatic plants, because aquatic plants can not only produce oxygen, but also consume oxygen. At night, the respiration of aquatic plants will consume oxygen in the fish tank. When the volume of the fish tank is too small, the oxygen in the water will be consumed by aquatic plants, which will affect the survival of the fish.
