LIGHTING 

• Light besides beautifying the aquarium helps in the photosynthesis of aquarium plants. Fish also require light to trace their food. Further, light which has a stimulating effect is also known to influence the growth of fish. It is also reported that fish receive vitamin-D from light which helps to build up resistance to diseases. Strong sunlight destroys bacteria and keeps the tank healthy. For a moderate tank, two bulbs of 60 watts each for eight hours a day can be used. However, it is better to use fluorescent lighting for promotion of plant growth and for even distribution of light.
