Nutrients essential to fish are the same as those required by most other animals. These include water, proteins (amino acids), lipids (fats, oils, fatty acids), carbohydrates (sugars, starch), vitamins, minerals and other supplementary additive such as probiotic and prebiotic. In their natural environment fish have developed a wide variety of feeding specializations (behavioral, morphological, and physiological) to acquire essential nutrients and utilize varied food sources. In past decade the nutritional requirements of various fish species have understood and technological advances in feed manufacturing have been obtained. This resulted in development and use of formulated and manufactured feeds to replace natural feeds in the aquaculture industry. The production and trade of ornamental fish is a profitable alternative in the aquaculture activity. In spite of economical importance of ornamental fishes, the nutritional information for these fishes is few or even no data is available. In this respect we had a review of some articles on nutritional requirements of ornamental fishes.
