The lifespan of koi fish is long, up to 60~70 years, but pay attention to these feeding techniques to make it live longer:

1. Raising koi fish first requires a powerful filter system For example, bottom filter, upper filter, filter barrel, etc., also need thermostats, thermometers and other equipment to control the water temperature within the temperature suitable for koi fish;

2. Koi fish do not have high requirements for food, as long as they are fed regularly and quantitatively;

3. Do not mix koi fish and turtles , tortoise excretion is large, easy to pollute the water quality.
