1. Temperature: The water temperature should not be lower than 15 ℃ or higher than 28 ℃. The most suitable temperature for its growth is 18 ~ 22 ℃. At the right temperature, it can increase metabolism, which is conducive to growth.
2. Water quality: change the water regularly and test the water quality regularly to ensure the fresh water quality. It is better to add a proper amount of salt to the water to prevent diseases. Bad or sick fish can affect their growth.
3. Oxygen supply: The oxygen consumption of fish will increase greatly in the process of growth. Therefore, it is necessary to ensure that the oxygen content in water is sufficient. Only in this way can the goldfish not suffocate due to lack of oxygen.
4. Feed: The nutritive value of animal feed is much higher than that of plant feed. When feeding, animal feed should be fed more. Like red worms, mealworms and other foods containing a lot of protein can be used as its staple food.
5. Space: Plenty of room for fish to swim. Fish often swim, which can improve its growth and development speed.
The choice of feed is very important for the growth of goldfish. If the fish are malnourished, the growth rate will certainly not be fast. If you want them to grow fast, you must first ensure the quality of feed. Feed should be selected with high protein content and low fat content to provide adequate nutrition for their growth and development. Generally speaking, animal feed is much more nutritious than artificial feed. They usually use water fleas, red worms, mealworms and so on as their staple food. Let the fish eat this kind of high protein, digestible food, is conducive to improving their growth rate.
