Koi and other pond fish will feed on natural sources such as algae and wayward insects, but they’ll benefit from a prepared, quality fish food. Just like other pet foods, not all fish food is created equal. You want to look for food that contains a high-quality protein along with stabilized multivitamins and probiotics.

Make sure the water is over 50 degrees before feeding fish, and even then, start with cold weather food until it is 60 degrees or more.

Only feed your fish what they can consume in about three to five minutes. In the summer you can feed them twice per day, but in spring and fall you should only feed them once per day.
