What koi do to save energy. 

Love the sound of the water flow. Never gets old.

Mine get fed 3 times a day thanks to my auto-feeder so they are generally pretty active. On really hot days they do spend a lot of time at the bottom relaxing but like yours are always happy to have food thrown in. 👍🏻

I feed mine twice a day, the odd time three times .. i have plants and algae on the sides so they are always foraging
