"Lots of people have successfully kept koi in indoor ponds with little to no sun exposure at all. As long as the water is good, thats all that matters."?<- ur ryt kennethc
let me explain to u...
Most of the animals that live on earth need sunlight in some way, either indirectly or directly. Koi need sunlight in both ways. Be it in the plants they eat or for their color pigments that they produce!
Natural sunlight brightens a Koi’s colors. This is most evident with the Yamabuki Ogon. If a Yamabuki Ogon is kept in an indoor tank with only regular lighting, its yellow color will fade. But, if the Yamabuki Ogon is put in an outdoor pond, its color will return within a couple months. The same applies for Kohakus, Sankes, Showas ect!
Koi actually look better in natural sunlight too. There’s something about the broad spectrum of light that the sun produces that brings out the natural beauty of Koi. A good way to see this example yourself is to take two pictures. Take one of a Koi when it’s indoors under a regular light and one of a Koi outside on a nice sunny day. Compare the two photos and it’s easy to tell which one looks better!
Natural sunlight also makes Koi healthier. The sun will warm the water up and will also boost a Koi’s immune system. Humans get vitamin D from the sun, fish do not. They must get it from plants or the small organisms that they eat. Vitamin D is essential for good growth and strong bones!
Natural sunlight is also beneficial to aquatic plants too. Aquatic plants require sunlight for photosynthesis, which is the process that a plant uses in order to make food and oxygen!
