2-3 cm Lanshou goldfish can eat some cooked egg yolk, bumper shrimp eggs, freeze-dried red worms or fish and shrimp, etc. At this time, their size is relatively small, and breeders need to cut them up before feeding freeze-dried fish and shrimp or red worms, so that they can eat normally. When they grow up, they can be fed with red worms, bumper shrimps, water earthworms, water fleas, protein worms and other foods, which can better promote their development. However, live bait is very easy to carry parasites and bacteria, so breeders should sterilize before feeding, and then feed.

2-3 cm Lanshou goldfish belong to fry stage, at which time they are relatively fragile, so breeders need to keep the water temperature constant and avoid the temperature difference exceeding 2 ℃. In addition, it is necessary to keep the water quality clean. It is best to change the water once every 3 days. The amount of water should not be too much each time, and it is best to control it at a quarter of the total water volume. To feed Lanshou goldfish in fry stage, we should follow the principle of eating less and eating more. We can feed it 3-4 times a day, and it is best to feed it 80% full each time. In addition, Lanshou goldfish need to bask in the sun every day to ensure their body color. Although the young fry do not show color, frequent sun exposure can sterilize and avoid bacteria breeding.
