Pelleted food by design is more compacted, providing more nutrition in the same amount of space, therefore care should be taken when comparing pricing on flake food versus pelleted food. In most cases, your best value is a pelleted food. For example, the human equivalent would be a bag of potato chips versus a bundle of carrots. Both items take up the same space but the carrots are more dense and nutritious than the potato chips. A small amount of pelleted food may have the same amount of food as a much larger amount of flake food. Additionally, pelleted foods typically allow the user to monitor the amount of food they are feeding because they float or sink rather slowly. This process allows the user to remove any food not consumed by the fish within a specific period of time. This helps eliminate overfeeding along with water quality problems and diseases.s associated with this common problem. Also, by eliminating overfeeding the food lasts longer. The differences between pelleted and flake food can be summed us in a few key words, better nutrition, better overall value and less water quality and health problems.
