A common error is to pre-soak pellets. This is based on the mistaken belief that it will aid in the digestion and prevent swelling inside the fish’s gut. This is an urban myth. Fish digestive systems contain copious enzymes and gastric acids that turn the pellet into pulp in a short period. If a pellet causes gastrointestinal issues, it’s usually due to use of ingredients with poor digestibility. This includes excessive grains and grain by-products and low quality protein. It is not due to pellet swelling. In fact, when you pre-soak pellet foods, you are encouraging nutrients and water-soluble vitamins and minerals to leach into the water before even introducing it.
