. Koi can live for 60-70 years in the wild. Koi is a kind of fish with a long life span, which is easy to raise. The life span of family-fed koi is generally about 25 years. However, poor feeding is not excluded. If the water quality deteriorates and the water temperature changes suddenly, the koi may die in a few years. If you want it to live longer, you must control the feeding environment. The water temperature should be stable at 20-25 C, and the water quality should be clear and odorless. Feeding should also be regular, and the food should be clean and healthy.
2. Normal feeding density: Be sure to leave enough space for Koi, so that it can grow comfortably and live long. Do not force a few koi into a small fish tank in order to save space in the fish tank. It's very likely that they won't grow. If the space in the fish tank is small, the oxygen will be insufficient, and the koi will not breathe smoothly.
3. Good water quality: Raising good water is the first step to raise good koi. It is best to change the water once every three to five days. When changing the water, it is enough to change one third of the fish tank, so as not to destroy the stability of the ecosystem.
