When raising tricolor arowana, it is very necessary to choose a fish tank with a relatively large space. Their body length can reach about 13-15 cm. In addition, in order to ensure the basic constancy of water temperature and quality, it is better to equip a set of constant temperature and filtration system with high performance in the water tank. Most importantly, in order to remove harmful substances in the water body, it is necessary to expose the water body to the sun before use. Generally speaking, they are relatively easy to raise except for the strict requirements for water quality. It is recommended that novice breeders try it.
1, water temperature: three-color arowana is more sensitive to changes in water temperature. Therefore, it is important to keep the water temperature constant when feeding. In addition to the installation of constant temperature system, when changing water, it is also necessary to control the change of water temperature difference, preferably not more than 2 degrees Celsius. For them, the water temperature is between 27 and 28 degrees Celsius, which is the most conducive to their growth.
2. Water quality: Since they are marine fish, it is necessary to control the specific gravity of the water body between 1.002 and 1.023. In addition, the PH value of the water body is preferably between 8.0 and 8.5, and the hardness of the water body is between 7 and 9.
3. Feeding: They don't have a high demand for food. When feeding, it can be fed with tubificidae, red worms, chopped fish, marine fish pellet feed and other foods.
