In recent decades, the global market for ornamental fishes has been growing steadily at the rate of 14% per annum
[1]. The management techniques have been optimized for gaining higher growth and production for food fish
species through intensive investigations. On the other hand, very little work is carried out on husbandry management
of ornamental fishes [2]. While food fish production focuses primarily on the total mass of fish produced [3],
ornamental fish sold by number and have to be of a minimum size to be accepted in the market. Therefore, the goal
of production is to produce highest number of fish of a given size within shortest possible time [2].
