1, the water quality needs arowana and weak acid soft water. Usually, the tap water of rivers is weakly acidic, which is soft water suitable for arowana. But tap water contains chlorine or fluorine, which is harmful to arowana and even leads to death.
Therefore, when raising arowana, you must store the water for 1 ~ 2 days or bask in the sun for half a day, so that the dissolved chlorine or fluorine in the water will disappear by itself. Chlorine can be decomposed if very little baking soda is added to water.
2. It is best to keep the water temperature at 24℃ ~ 26℃, especially for feeding silver dragons and black dragons. The water temperature needs to be raised to 28℃ ~ 30℃. Arowana is very sensitive to the sudden increase or decrease of water temperature, which is easy to cause nervous system shock, absorption interruption and death.
To raise arowana, we must strictly control the constant water temperature. Especially for arowana in aquarium, the temperature difference between new and old water should not exceed 2℃ when changing water, and new water must be used to injection and dispersion when injecting. When the arowana is transported to the new environment for culture, it should wait about 15 minutes, and then put the fish in when the water temperature of the carrying container is close to the water temperature of the new stocking environment.
3. Clean up all kinds of filth in aquaculture ponds and aquariums in time. In order to ensure that there is enough dissolved oxygen in the pool or aquarium, oxygen increasing equipment should be provided.

Matters needing attention in arowana culture:
1, you don't need to change the water often. The general aquarium filter can meet the needs of arowana. Arowana should not change water too often or too much, so as not to cause scales or fins to fall off (although it can be regenerated), and it is advisable to change 1/4 every time. Submersible pump can be used to make the fish tank form water flow and maintain the vitality of arowana.
2. Food needs are diverse. Arowana is a carnivore, and its recipes are mostly frogs, loaches, crickets, goldfish, grasshoppers and shrimps. The food of arowana should not be too single, and it should be changed frequently. Meet the needs of arowana's taste and physical growth, so a comprehensive feeding method is conducive to arowana's growth.
The water temperature should be constant. Arowana is very sensitive to the sudden increase or decrease of water temperature, which easily leads to nervous system shock, absorption interruption and death. To raise arowana, we must strictly control the constant water temperature. Especially for arowana in aquarium, the temperature difference between old and new water should not exceed 2℃ when changing water. The water temperature of arowana should be kept at 24℃~26℃.
4. The cylinder should be large and stamped. Arowana is large, and the length of aquarium should exceed 120cm. In order to prevent arowana from jumping out of the water when it is frightened, the aquarium must also be covered.
