a year. If they are well raised, goldfish can grow about 8 centimeters a year. But how much goldfish can grow in a year depends on the breeding method and the breed. If you want goldfish to grow well, you can eat less and eat more when feeding, and raise them scientifically. If many fish are kept together, it is better to choose a bigger tank. If the tank is too small, it will affect their swimming and make them not get good exercise. Over time, it will affect their growth rate. Also ensure enough oxygen to avoid lack of oxygen in goldfish. We should also pay attention to food and give them more nutrition.
? If you want goldfish to grow well, first of all, you need to pay attention to feeding, eat less and eat more, and give them more nutritious food, such as shrimp, earthworms, mealworms and so on. These foods can supplement their protein. You can also feed cooked millet, because millet is rich in vitamins and minerals, which can promote their gastrointestinal digestion. Feeding needs to pay attention to seasonal changes, and the amount of goldfish eaten in different seasons will be different. In winter, goldfish have a slow metabolism and should reduce their appetite appropriately. In summer, goldfish have a large amount of activity, which can be increased appropriately, but should not be excessive to prevent them from eating too much.
