goldfish is easy to raise. They have low requirements for water temperature and water quality, and have strong adaptability to the environment. When they are raised artificially, they can grow and develop well as long as they can ensure the stability of their living environment.

1. Feeding: Goldfish are not picky about food, and they will eat most foods that fish can eat. Goldfish don't eat much, so breeders need to decide the feeding amount according to their eating state. Artificial goldfish can be fed with animal feed and plant feed. The animal feed suitable for goldfish is abundant shrimp, red worms, water fleas, water lice, water earthworms, bread worms, yellow mealworms and so on. Plant feeds suitable for goldfish include vegetables, fruits, aquatic plants, moss, rice and so on.

2. Water temperature: Goldfish have strong adaptability to water temperature. They can live in water temperature between 18-32 ℃ and 0-39 ℃. When reared artificially, they can grow well as long as the water temperature can be kept between 20-30 ℃.

3. Water quality: Goldfish like weakly alkaline water, and breeders can keep the PH value between 7.5 and 8.0. Usually, water can be changed once every 3-5 days, and the amount of water changed each time can be controlled at one third of the total water volume.

4. Oxygen: Although goldfish's demand for oxygen is not very high, breeders also need to use oxygen pumps to increase oxygen for them when the temperature is high or the air pressure is low.
