We feed our fish to maximize and enhance their vibrant colors, growth, and longevity. Koi are omnivorous opportunistic feeders that need a balanced diet of protein and plant matter. Just don’t overfeed, it’s better to under feed than overfeed! Take out uneaten food before it spoils the water-adding to algae blooms.    

Healthy Water=Healthy Fish

What type of diet should I feed my fish?  

Koi are naturally bottom feeders, so feeding floating food is best. There are several types of food on the market-flakes, sticks or pellets. Feeding a mix of foods and cold water or wheatgerm based diets are great for the Pacific Northwest, where we have colder water.

Protein-helps increase growth & reproduction 31-42% crude protein Fats give fish energy, 2-3% crude fat. Carbohydrates offer an energy boost but also help fish process nutrients (cheerios and oatmeal). Vitamins and minerals regulate their metabolism and Vitamin C aids immunity.

How do I start to feed my fish in the Spring?

Start off with Cold water fish food / wheatgerm diet, or you can feed uncooked Quaker Oats or pre-soaked Cheerios. Feed sparingly to start to reduce the risk of illness- if scales beginning to raise or turn red, stop feeding and watch them. If the scales don’t go down, try treating with an antibacterial medication and move fish into a heated hospital tank.
