Observing and feeding fish is a great way to relax and enjoy your backyard waterscape.

Start feeding pond fish Growth & Vibrance food when water temperatures are above 50°F. When introducing a new food, slowly float only one or two pellets on the pond's surface until your fish show interest. Only feed fish what they can eat within five minutes, and skim out any leftover pellet or debris that could decay into muck. Our fish food may interest other pond wildlife, and rest assured that it will not harm any turtle, frog, catfish, snail, or other aquatic creature who takes a bite of the tasty snack.

The Pond Guy Spring & Fall Floating Fish Food contains an easy-to-digest formula for colder temperatures. If water temperatures drop below 40°F, pond fishes enter a hibernation state. Do not feed fish during this time. The Pond Guy Growth & Vibrance Fish Food helps pond fish increase size and energy, while also enhancing color and wellness.
