If you want the seven-color fry to grow faster, you can use a 15-30 cm bare tank to raise it. The water temperature for raising fish fry is controlled between 28 and 30 degrees, and the water quality is slightly harder. During the three weeks after birth, the fry can only maintain their strength by feeding on the nutrient solution of the parent fish and eating brine shrimp, and the intake of nutrients may not be enough. Therefore, at this stage, the farmer can add some vitamin solution dropwise to provide nutrition.
Five days after the fry are born, they can be fed with frozen brine shrimp. When the fry grow to about 2 cm, they can be fed hamburgers. Feeding should pay attention to frequency, preferably 4-6 times a day, but not too much each time. Feeding a small number of times is beneficial to their growth.
When the seven-color fish fry grows to 2 centimeters, it can be fed with broken hamburgers. There are many nutrients in hamburgers, which are conducive to the healthy growth of colorful fish. It is suggested that the breeders feed the colorful fish a few times a day, and change the water in time after they eat, so that they can grow fast and well.
