The broodstock has spawned, and the broodstock after spawning will soon begin to feed on their own eggs, so the broodstock should be fished out in time. However, it may be beneficial for the broodstock to recover after giving birth if you let the broodstock eat a few eggs. After all, the protected broodstock with a spawning bed may only eat a few eggs, and these nutrients will be very beneficial to the broodstock. After the broodstock is fished out, the spawning box should be sealed in time to avoid damage to the eggs by light.

The most worrying thing at this time is the water quality in the breeding box . Do not change the water at this time, pay attention to testing. Fertilized eggs hatch within 24 hours, don't disturb them, the larvae at this time rely on the yolk sac to survive, after about 4-5 days the larvae start to swim, then you can take out the spawning bed and start feeding them food in a weaker light and gradually increase the intensity of the light. The bait for larvae is preferably live bait such as water. Although larvae can feed on egg yolk water and brine shrimp larvae, because they cannot be illuminated by strong light at this time, it will cause great trouble to the maintenance of water quality, so try not to use these bait. The amount of feeding is about 4 times a day, and the amount that can be eaten in ten minutes each time.

The daily residual bait and excrement must be cleaned up in time, and some fresh water that has been dried for a long time should be slowly poured into it with a watering can to keep the water quality clean. After about 3 weeks, the juveniles can be raised in the adult tank. If it is a farm, after the broodstock spawns, the spawning beds with attached fish eggs can be gathered together for incubation and breeding, but this requires certain skills.
