1. Water temperature: Small Arowana is just born and has poor adaptability to the outside world. Breeders need to ensure that the water temperature in which they live is constant. If conditions permit, it is recommended to install heating rods to keep the water temperature between 26-28 ℃.

2. Water quality: Small Arowana also has strict requirements on water quality, and they like weak acidic soft water. When rearing artificially, the PH value can be kept between 6.5 and 7.5. They are sensitive to external changes, so the amount and frequency of water change should not be too high.

3. Oxygen: Small Arowana needs more oxygen during its growth and development. It is best for breeders to install an oxygen pump for them, so as to ensure sufficient oxygen. When playing oxygen, it is best to play oxygen continuously in a small amount, and try not to play for a while and stop for a while.

1. Food choice: The small Arowana can not eat much food because they are just born and have poor digestion ability. At this time, they can be fed more minced meat, lean meat, red worms and yellow mealworms of fish and shrimp.

2. Feeding frequency: The feeding frequency of small Arowana needs to be higher, because they eat less, but they have higher demand for food and nutrition. At this time, it is best to feed twice a day.

3. Feeding amount: The feeding amount of small Arowana can also be larger, and it can be fed to 80% satiety every time.

4. Feeding method: Breeders can train Arowana to eat on the upper layer at an early age, so that they can avoid dropping eyes and tails during their later growth.
