Temperature: Goldfish living at 18 ~ 22 ℃ can accelerate metabolism and grow faster. Water quality: change water regularly to ensure fresh water quality. Oxygen supply: the growth of fish needs to consume a lot of oxygen. There should be enough oxygen in the water to ensure its healthy growth. Feed: animal feed with high nutritional value should be selected for feeding, generally dominated by red worm and bread worm. Space: sufficient space is conducive to fish swimming and promote its development. 1、 How can goldfish grow fast 1 Temperature: the water temperature shall 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 improve metabolism and is conducive to growth.
2. Water quality: change the water regularly at ordinary times, and test the water quality regularly to ensure that the water quality is fresh. It is best to add an appropriate amount of salt to the water to prevent diseases. Fish in bad condition or ill will affect their growth.
3. Oxygen supply: the oxygen consumption of fish will increase greatly during their growth. Therefore, it is necessary to ensure that the oxygen content in the water is sufficient. In this way, the goldfish will not suffocate due to lack of oxygen.
4. Feed: the nutritional value of animal feed is much higher than that of plant feed. When feeding, feed more animal feed. Foods containing a lot of protein, such as red worms and bread worms, can be used as its staple food.
5. Space: sufficient space is conducive to fish swimming. Fish often swim, which can improve its growth and development speed. 2、 What feed goldfish eat grows fast. The choice of feed is very important to the growth of goldfish. Fish will not grow fast if they are malnourished. If you want them to grow fast, you must first ensure the quality of feed. Feed should choose the species with high protein content and low fat content, so as to provide sufficient nutrition for their growth and development. Generally speaking, animal feed is much more nutritious than artificial feed. Water fleas, red worms and bread worms are usually used as their staple food. Let fish eat this kind of high protein and digestible food, which is conducive to improving their growth rate. （JinYuZenMeYangChangDeKuai，ChiShenMeSiLiaoChangDeKuai）
