Pond fish eat live or dried insects, worms, and grubs. Pond fish must be kept in a pond that has proper pH levels and proper air and water temperatures to ensure proper diet and eating habits.
One of the most important aspects of feeding pond fish is watching the fish throughout the process. Fish will only eat what they need to eat as they do not overeat. Therefore, if a fish owner is feeding too many dried insect flakes to the fish, then poor and possibly deadly conditions will be created for the fish. The fish should be fed slowly instead of all at once, noting how much is eaten so that the proper amount is fed each time.
It is also important that food not be thrown out to the fish. Food should be set at the edge of the pond, allowing the fish to associate food with the pond owner's presence. They will soon start to swim up towards the pond owner to eat the food, so the pond owner can assess the health of the fish on a daily basis. It is also crucial to remember that, in colder climates, there will be times when the fish cannot be fed. Once water temperatures have settled at 52 degrees Fahrenheit, then the fish cannot be fed. At this temperature, they cannot properly metabolize or digest their food, and feeding them can lead to additional health issues.
