The diet my Koi recieve is Vital if they are to thrive and grow and stay alive, my Koi are feed roughly twice a day, which in my opinion is'nt enough, so I plan on installing an Auto-Feeder insuring my Koi get feed 5 times a day as recommended by professional Koi Keepers, this year I wont to make sure my Koi consume much more, At the minute there eating about 3.5KG off food a Month. This year I only just started feeding my Koi 2 weeks ago due to the long Winter, I stopped feeding them around Mid October, At the minute am feeding them Tetra pond sticks (Heath and Colour Mix) to restore my Koi's bodily functions and colour, around late May I shall feed my Koi a Standard food with 30% Protein which contains vitamins, then around July and August they shall be feed Growth Food which has 40% protein, I also feed my Koi Sweetcorn, Oranges, Prawns no and again and not to mention wholemeal bread, they love it and its good for hand-feeding. The following pictures are some of the Foods I use:
