According to the thickness of the scales of Arowana, it can be divided into two kinds: thick-framed Arowana and thin-framed Arowana. As the name implies, the scale frame of thick-framed Arowana is thick. When raising, you should first choose a suitable fish tank. Because they are generally larger, generally about 50 cm, and even some can grow to about 60 cm. Therefore, when choosing a fish tank, it is necessary to prepare at least one fish tank above 120 × 60 × 60. In addition, it is necessary to equip the infrastructure in the fish tank. Filtration system, oxygen pump and heater are all indispensable. Only in this way can they ensure a good living environment. Generally speaking, it is not difficult to raise them, so long as they are carefully cared for, they are more suitable for novice breeding.

1. Water quality: Good water quality environment is one of the necessary conditions to ensure the healthy growth of coarse-framed Arowana. They are suitable for living in weakly acidic water environment. It should be noted that the water quality will gradually harden after long-term living, so it is very necessary to change water frequently.

2. Water temperature: They are very sensitive to changes in water temperature. When feeding, it is recommended to keep the water temperature between 24-29 ℃. In addition, when changing water, we should pay attention to controlling the temperature difference. Do not let the water temperature suddenly change. It is recommended to neutralize the water temperature of the old and new water before changing water.

3. Feeding: They still have certain requirements for food. When breeding, fish, shrimp, insects and other foods can be fed. It is best to feed a variety of foods together, which can ensure that they get balanced nutrition.
