An exact amount of flake food per fish cannot be determined, since the requirements differ. The amount of food is correct if the fish absorb the portion completely within a few minutes. Too much flake food is harmful, like any fish food, in excess quantities. The excess sinks to the ground and impairs the water quality. If the fish absorb too many flakes, they excrete more substances that also pollute the water. Even high-quality filter systems cannot cope with this in the long term.
Growing young fish require smaller portions of high-quality food several times a day. Flake food is usually not suitable for breeding. For older and larger fish, a two to three times daily feeding with one fasting day per week is usually sufficient. If your aquarium fish always seem hungry, check the amount of food: being hungry can be a sign of overfeeding. Too much energy stimulates growth and fat storage in fish. A few fasting days and then moderately dosed flake food will regulate the feeling of hunger.
