1. How to raise silver dragon fry 1. Fish tank: Silver dragon fry do not require high space, but their growth speed is relatively fast. Breeders had better prepare enough space for them first, so as to avoid discomfort when changing cylinders later.
2. Water temperature: Silver dragon fry was born soon, and its adaptability to environment was poor. Moreover, it is at a critical stage of growth and development, so it is best for breeders to keep the water temperature between 28-32 ℃, so as to make them grow and develop faster and help them adapt to the external environment faster.
3. Water quality: Arowana likes weak acidic water quality, and the newborn Arowana fry has weak constitution, so it is best for breeders to keep the PH value between 6.5 and 7.5. Usually, you can change water once every 3-5 days, and the amount of water changed each time should be controlled at one third of the total amount of water.
4. Feeding: When the fry of Arowana is less than 20 cm long, the breeder can only feed them some digestible live bait, such as bumper shrimp, Daphnia, red worm, etc. When they grow to more than 20 cm, they can be fed with some large live bait and synthetic feed.
2. What should be paid attention to in the culture of Arowana fry1. Temperature difference: Arowana itself is sensitive to temperature difference, especially Arowana fry, which is more sensitive to the fluctuation of water temperature. Breeders need to use heating rods to keep the water temperature in a stable range, so as to ensure that they can live normally.
2. Feeding: Silver arowana should not be fed too full, because they do not like activities after eating too full. In the long run, fat accumulation is easy to occur. It is best for breeders to feed 70% full every time, and it is best to turn on the wave-making pump after eating, so that they can move for a while.
