before the female Dutch phoenix fish spawns, the anus will protrude obviously, may see the oviposition tube to stretch out with the naked eye. The whole spawning stage lasts about 2-3 hours. At the end of spawning, the small fish can be fished out after about 30 hours with the parent fish. Before spawning, the female fish will choose the spawning place, such as sunken wood, wide leaves of aquatic plants, rocks, sand pits at the bottom of the tank, etc. At this time, the male Dutch Phoenix fish will accompany the female fish all the time, and if this situation is observed, the female fish will begin to lay eggs.
for spawning of Dutch phoenix fish 1. Keep the environment quiet: Dutch phoenix fish has high requirements for water quality and should maintain a good and healthy living environment. When the female Dutch phoenix fish is giving birth, it is necessary to ensure that the environment is quiet and that they are not disturbed as much as possible. Moreover, other fish in the fish tank can be fished out first to ensure that the parent fish will not be disturbed when spawning. A female protected in this way can lay 100-200 eggs.
2. Control the breeding temperature: The hatching rate of these eggs is the highest at 29 ℃. The water in the tank should be kept weakly acidic, and the temperature is about 28 degrees Celsius. Some filtration equipment and oxygenation equipment should be installed in the tank to ensure that the oxygen content in the water is sufficient.
3. Ensure nutrition supply: During the breeding period, the female fish needs more nutrition to maintain normal life activities. You can feed more animal feed, such as live bait red worms, shrimp, blood worms and so on. However, with the approaching of the delivery period, the feeding amount should be reduced appropriately to prevent the water quality from being destroyed.
