Tropical fish stocking and mix proportions

1: Stocking Density The stocking density of tropical fish should be based on the size of the fish, the condition of the water body, and the inflation conditions. When the water temperature is adequate and the oxygen is sufficient, the general specification is a 60 cm 40 cm 35 cm aquarium, which can store 30 to 40 small fish. 15 medium-sized fish, 4 to 6 large fish, 40 cm, 30 cm, and 30 cm aquarium, can be stocked with 20 small fish, 5 to 10 medium-sized fish, and 4 to 6 large-sized fish.
2. In order to increase the ornamental ratio, tropical fish are often polycultured. Polyculture fish must have similar water quality and mild temperament. Fish that swim endlessly throughout the day cannot be polycultured with pleasing fish; ferocious fish cannot be polycultured with temperate fish.
