The bottle of fish food says I should give a pinch twice a day, but this seems like a lot. That would be more food than any small fish could eat. Goldfish are great pets. They are easy keepers and provide their owners with wonderfully quiet companionship. But it is easy to overfeed them and too much food can be harmful to your fish.
Overfed fish are less active and live a shorter life.
Here are some guidelines I recommend for feeding your little friend. First, feed him only once daily. He doesn t really need that other meal at all. Second, when you sprinkle the fish flakes on the water, give him about as much as you could fit under your fingernail. If any flakes fall to the bottom of the tank before he consumes them, you have fed him too much.
