It is best to feed 3-4 times a day for 3 cm Lanshou golden fry, because they are small now, but they have a great demand for food and nutrition, so breeders should feed them several times in a small amount, so as to ensure that they can get more food and nutrition. When feeding, the breeder should control the amount of food, and it is best to eat it within 5 minutes each time.

The fry stage of Lanshou goldfish is the key stage of development. Breeders should ensure the nutrition of food, and usually feed more animal feeds such as minced meat of fish and shrimp, red worms, bread worms, Tenebrio molitor and Daphnia, which can not only promote their body development, but also promote the development of their head tumors.

Lanshou goldfish change water every few days, depending on the feeding environment and whether there is a filtration system. If the water quality is good and the filtration system is installed, the breeder can choose to change the water once every 3-4 days. If the water is contaminated rapidly and there is no filtration system, the breeder needs to change the water every 2-3 days. Lanshou goldfish like old water, so it is best for breeders to install a filtration system to avoid changing water too frequently, which makes them uncomfortable. When changing water for Lanshou goldfish, we should pay attention to the amount of water changed. It is best to control the amount of water changed every day in one third of the total water volume.
