1, water temperature: goldfish is a temperature-changing animal, and its adaptability is relatively strong. Under normal circumstances, they can grow in water temperature between 0 and 38 ℃. When culturing artificially, it is best to keep the water temperature between 18-25 ℃. In this temperature range, their growth state and speed are the best.

2. Water quality: Goldfish can adapt to a wide range of water quality, and they can live in weak acid, weak base and neutral water. However, their favorite water quality is weakly alkaline, and it is best for breeders to keep the PH value between 7.2 and 7.4 if they have the conditions. In addition, before changing water, breeders should dry the water for several days to avoid chlorine affecting goldfish's health.

3. Food: Goldfish's feeding habits are miscellaneous, so breeders can choose to feed with animal feed and plant feed. This can not only ensure their adequate nutrition, but also ensure balanced nutrition.

1. Environment stability: Although goldfish has strong adaptability to the environment, it is sensitive to environmental fluctuations. Breeders need to keep the environment in which they live stable so that they can grow better.

2. Reasonable feeding: Goldfish do not feel full, so it is best for breeders to feed them regularly and quantitatively. Juvenile goldfish need to be fed twice a day, and the amount of each feeding can be eaten within 5 minutes. Adult goldfish can be fed once a day, and the amount of each feeding can be eaten within 10 minutes.
