Choosing the right food and feeding it at the right time affects the overall health and longevity of your fish. As seasons change, and water temperatures rise and fall, so do the nutritional needs of your fish. To make the proper adjustments in diet and portion size, you need to use an accurate thermometer to measure water temperature on a regular basis.
As water temperatures fall, the metabolism of koi and other fishes slows, and their ability to resist disease decreases. To compensate, at around 60°F, begin mixing their diet with an easier-to-digest, wheat germ formula. At around 50°F, switch to it completely. These foods offer high nutrition, are fortified with vitamins and minerals to help boost the immune system, and help reduce fish waste.
Growth Formulas for active fish
Staple formulas offer high quality protein, vitamins, and minerals suitable for all fish, but at lower energy levels than growth foods. They provide a good maintenance diet throughout the summer months.
Color Foods for vibrant fish
For healthy fish, keep an eye on water temperature, use a variety of quality foods, adjust foods seasonally, and adjust portion sizes.
