FEEDING
Food must provide fish with the elements needed to "build" their body (proteins)
and the energy (from proteins, carbohydrates, and lipids) required for its smooth
functioning. Feeding a fish properly ensures that it will grow satisfactorily, as
well as facilitating its reproduction and helping it to combat disease. Quality
and quantity are two important concepts in feeding: an aquarist must learn to avoid
over-feeding and to diversify the food supply.
