Seedling feeding of swallow fish
Small fish swim away from the plate for 5-8 hours before feeding open bait, to feed migratory water or harvest shrimp larvae. Feeding egg yolk water is not good, small fish do not like to eat, and bad water; changing water is not realistic, you will find that it is impossible to operate. Feed less for the first time, so that every fish can eat it. If you don't digest too much, you will die instead. After the first feeding, you have to feed the fish for a second time after about 8 hours, so that the small fish have enough time to digest and adapt. Drain the "yolk water (milky mucus)" in an empty stomach. After that, it will be easy to manage. You only need to feed it three times a day, and the amount of each feeding should be finished within one hour.
The change of water for small fish should not be changed for the first time until the third day of feeding, and the amount of water exchange should be controlled at 10% 15%. First, carefully absorb the yolk water excreted by small fish, and then add fresh water that has been dried and at the same temperature. Add water gently, slowly and slowly, never rushing to the small fish. After that, change it every day or two days.
From the seventh day of feeding, you can feed the little red worms; on the 15th day or so, the small fish will grow dorsal fins, and then the small fish can be fed to the red worms. You can transfer them to the feeding tank and use the method of water. Slowly sink into the feeding tank with the incubator, and then gently take out the incubator. Wait until the 30th day, you can feed them all the bait you can provide, and the water can be changed according to the big fish. At this point, you can say that your swallow fish have bred successfully, and you can watch your pack of wolves grow day by day.
