can Koi grow? Koi can grow to 50-150 centimeters. If breeders raise them scientifically, they may break through the limit of 150 centimeters. To make them grow bigger, breeders should pay attention to the following three points:
1. Water temperature: Although koi are cold-water fish and have strong adaptability to water temperature, it is better to control their living water temperature between 20 and 25 degrees, which is conducive to promoting their growth and development. In addition, while controlling the water temperature, we should also pay attention to oxygenating them at all times to prevent the oxygen content in the water from being too low and causing them to suffer from hypoxia.
2. Food: Koi is an omnivorous fish, and basically accepts all comers. So when we feed them, we should pay attention to the fact that the food should not be too single and keep the nutrition balanced. In addition to feeding, they can also be fed with some high-protein live baits. It is necessary to fix a reasonable feeding time for them and strictly follow the implementation. In addition, the amount of food each time should not be too large, eat less and eat more, and control it at 70% full.
3. Water quality: Water quality is also very important for the growth of koi. When raising them, it is better to install a filter device in the water to keep the water clean and stable. It is better to change the water 1-2 times a week to ensure that the dissolved oxygen in the water is sufficient.
can Koi live? The life span of Koi is relatively long. As long as it is properly raised, it is no problem to live for 60-70 years. But if they are not bred properly, they will not be able to survive for so long. If you want them to live longer, you also need the above three points. In particular, the control of water temperature and quality is very important.
