Colorful 2 cm fry should be raised in a small bare tank. In this way, it is easy to clean up, change water conveniently, not easy to pollute water quality, and fry can easily eat food. The water temperature for raising fish fry is controlled between 28 and 30 degrees. The water quality should be slightly harder, and the water contains more minerals, so that the fry will grow better.
During the three weeks after the fry is born, they can only maintain their physical strength by sucking the nutrient solution secreted by the parent fish and eating brine shrimp, and the nutrition they take in is not enough. Therefore, the farmer can drop the vitamin solution in the water. Water should be changed half an hour after each feeding, and one third or one quarter of the water should be changed at a time. The tank should be filtered by biochemical sponge filter to prevent the fry from being sucked away by the filter.
The 2-centimeter fry can be fed frozen brine shrimp, homemade minced "hamburgers" containing nutrients, or nematodes. When feeding fish fry to eat nematodes, they should be cleaned to avoid nematodes carrying parasites, which will cause fish fry to get sick. A culturist needs to feed the seven-color angelfish fry for a few times, and the seven-color angelfish fry can be fed 4-6 times every day. When they finish eating, they should change the water quickly. In this way, the fry can grow up healthily.
