Golden koi can grow. Some people say that the largest golden koi I have ever seen is about 1.2 meters. I don't know if it is true or not, but according to the imagination of the average lifespan of golden koi of more than 70 years, it is almost inseparable!

Next, let’s take a look at the feeding requirements of golden koi!

It is best to raise it in a fish pond. The space is relatively larger than that of the aquarium, which is also helpful for the growth and development of golden koi. The stocking density of the fish pond is preferably 1KG/ton of water. If the golden koi are raised in the aquarium, the width of the aquarium should be large and the stocking density should be well controlled. The size of the space is one of the important conditions for how big the golden koi can grow.
