How often does Arowana lay its eggs and hatch its eggs

Female arowana usually lays eggs in 6-12 years, and they can lay eggs about 3 times a year. If the breeding is reasonable, eggs can be laid once a quarter. Generally, the eggs laid can hatch small fish with yolk sac in 40-60 days. Small fish can successfully hatch into young fish after living in yolk sac for about 8 days. At this time, they can swim freely in the water and eat. After the small fish hatch successfully, they need to be isolated from their parent fish in time to avoid being eaten by mistake.

1. How long does Arowana spawn

The development and maturity of Arowana are very long. If it is a female arowana, they usually enter the breeding period in 6-12 years and then start laying eggs. If they are male Arowana, their breeding period is longer than that of female Arowana. They usually enter the breeding period in 5-16 years. At this time, they can fertilize eggs and hold fertilized eggs in their mouths to raise their offspring. Most of them can lay eggs three times a year. If they live in a reasonable environment, it is ok to produce eggs four times a year.

2. How long does the eggs of Arowana hatch

The fertilized eggs of Arowana usually hatch in 50-70 days. After fertilization, the eggs will stay in the mouth of male fish for 40-60 days, and then hatch from the original fertilized eggs into small fish with yolk sac. After living in yolk sac for about 8 days, they will hatch into young fish.

Before breeding Arowana, it is necessary to select suitable parent fish, put them in a new feeding tank, adjust the ambient temperature to about 30 ℃, and adjust the PH to 6.5-7.5. Suitable living environment is helpful for them to fertilize.

During the hatching period of Arowana, it is necessary to provide them with a quiet place. If the surrounding environment is too noisy, males may swallow fertilized eggs in their mouths, which will affect the survival rate of their offspring. After successful hatching, the young fish must be separated from the parent fish, otherwise the parent fish may eat the young fish.
