for fish? In fact, it is very simple to make oxygen for fish. Just prepare an oxygen pump, put it in a slightly higher position, and put the air head to the bottom of the water. In addition, oxygenation tablets can also be used to increase dissolved oxygen, but this is an emergency method, usually used in fish ponds, and rarely used at home. In addition, although aquatic plants can also produce oxygen through photosynthesis, the content is very small, so it is unrealistic to expect it to maintain dissolved oxygen.
? 1. Arowana: Arowana is a large ornamental fish with a length of up to 65 centimeters and a life span of decades. It has a ferocious temperament, mainly feeding on fish and shrimp, aquatic insects, frogs and so on. There are many kinds of artificial breeding, such as silver dragon, golden dragon, red dragon and so on. Because of its large size, the demand for dissolved oxygen is also high.
2. Koi: Koi is an ornamental fish bred from carp. It has a strong physique, bright colors and many patterns. Its feeding habits are miscellaneous, its temperament is mild, it is easy to raise, and its adaptability to temperature is strong. It also consumes a lot of oxygen, so it must be oxygenated to keep it alive, otherwise it will float.
3. Parrot fish: Parrot fish is an ornamental fish bred from two kinds of fish. It has certain physiological defects. Its mouth can not be closed, so its ability to control the flow of water is weak. Therefore, its demand for dissolved oxygen is also very high. If the oxygen content is low, it will die.
