Buy between 10-30 goldfish with pellet feed (small fish feed is not good, the particles are too fine) every day in the morning and evening to feed once a day, twice a day, once to the amount that the fish can eat in 3 minutes, the fish is not full, so it is better to feed less than to feed more.

Due to the small size of the domestic rectangular aquarium, you must not raise more goldfish, and it is better to raise less than more. Generally speaking, the fish are large and have a small number of feeds; More in winter and less in summer; When the water temperature is low, you can raise more, and when the water temperature is high, you can raise less.
