Swallow fish
When the swallowfish is raised to a certain level, it will grow. The swallowfish is an egg creature, so it will continue to ovulate during the growth period. During the growth period of the swallowfish, it will continue to ovulate. When arriving, all owners should fully understand the different growth periods of swallowfish and create a good environment for the swallowfish.
Choosing the best breeding fish for the growth of swallowfish is the first step. So when choosing breeder fish, you must first understand how to separate male and female swallowfish. The head of the male fish is slightly raised, while the head of the female fish is flat but the belly is rounded. Swallowfish can be considered ready for growth after they reach ten months of age. The matching of giant mermaids requires willingness, and usually the ones that have been successfully matched are selected from the giant mermaids raised in a tank. If the pairing is determined, most of them will fail. Once you have broodstock that can grow, you should pay attention to the observation. If the two fish swim around together and the anus is drooping, move the two broodfish into the growth tank and prepare a good mermaid growth barrel. At this time, you will see The two parent fish begin to clear the place of growth. After 48 hours, the female fish will lay eggs, and the male fish will be fertilized after close intercourse. After spawning, the broodstock will continue to swim on the eggs to provide oxygen to the eggs. Each female fish can lay hundreds to thousands of eggs. Male and female fish will eat white eggs that have not been successfully fertilized, but they will not eat eggs that have been successfully fertilized. You can rest assured about this.
Concerning the growth of swallow fish, what should be emphasized here is water. What kind of water is usually used for growth? No matter what kind of water you use, it is ok if the water temperature is 1℃ higher than usual, and the water should be changed as usual. I usually use tap water for fish farming, so I also use tap water for growth. I do not heat the water when changing the water, so that the temperature of the growth tank can fluctuate flexibly, which has a good stimulating effect on the species of fish. However, special attention should be paid to the speed of adding water, which must be slow and should be controlled at about half of the drainage speed. It cannot directly rush into the fish. It may be added to the upper filter box for buffering.
At the end of the incubation process, we can take two methods: natural incubation or artificial incubation. Natural incubation Under such circumstances, the parent fish will protect the eggs, and the male and female fish will take turns to fan the water untilThe young fish hatch out of the membrane. Now we will focus on artificial incubation. After the parent fish lays eggs, we must immediately place the spawning board in the incubator and put in water with the same temperature as the water in the tank to create a "water fairy" to replace the parent fish, and then slowly Just wait for the eggs to hatch. Pay special attention here to the extreme temperature of the water in the incubator, and try to keep the water temperature constant.
It is best to use a birthing board for the egg bed. It is okay to use pots, pots, tubes, etc., but the swallow fish still prefers Good board, there is no extravagant requirement for the material of the board, as long as it is flat and smooth; the best is a green plastic board with a length of 20-25 cm and a width of 8-10 cm, tilted at 10-20 degrees (to simulate the blades of aquatic plants) (natural angle), the bottom of the tank is separated from the bottom, and the top of the spawning plate is about 3 cm below the water surface. Swallowfish eggs are generally laid within 5-20 cm below the water surface.
In addition, the method of artificial incubation has its limitations after all, so there will be color changes during the entire incubation process. White dead eggs. Use a straw to drain away immediately to prevent water mold in the entire box of water!
