In terms of feeding, live water fleas are the best choice. Metabolites are not easy to disperse and can keep the water clean.

3. Synthetic feeds

Among them, high-quality synthetic feeds belong to yeast, which can rapidly differentiate the metabolites of goldfish, which is beneficial to the preservation of water quality. Inferior synthetic feeds are not only nutritious, but also contain artificial pigments, which can discolor water bodies.

The bait for feeding small goldfish should be fresh, and the nutrition should be balanced. Can not be fed, natural bait can be sterilized with potassium permanganate, cleaned with clean water before feeding.

Goldfish are gluttonous, so every feeding is 80% full. If you raise fish outdoors, feed less or not on cloudy days. Each feeding should be selected in a fixed position, and the specific selection depends on the environment.

4. The density of fish culture in the tank

The number of goldfish cultured in the aquarium is limited, and each 1-year-old goldfish takes up 10 liters of water. For example, the volume of the 80X40X40 aquarium is 128 liters, and it can raise 12 fish of 1 year old.

5. Aquarium water temperature requirements

Although goldfish can survive in a wide temperature range, they can still maintain life under the ice in winter, as long as they are not exposed to the sun on hot days. It can live a normal life, but if the temperature changes sharply, it will lead to illness and death. Some pet editors suggest that when buying fish, pay attention to the water temperature of the aquarium store and the water temperature of your fish tank, and the deviation should not be too large.
