LED lights should be selected for fish tank lighting. There are many kinds of fish tank lighting lamps, such as incandescent lamps, halogen lamps, fluorescent lamps, fluorescent lamps, LED lamps, etc. Different lamps have different prices and different functions. Ordinary fish tank lights can only provide lighting function, and a better light spectrum will be suitable for the growth of fish, which will help its development, and some can promote the discoloration of fish without allowing algae to multiply.

1. Fluorescent lamps: Fluorescent lamps are the most common fish tank lamps at present, which are generally white, blue and red. There are many kinds of it, but its functionality is limited, and it can only provide lighting. However, when it is put into grass tanks and seawater tanks, it can also provide photosynthesis for aquatic plants, which is beneficial to the release of oxygen.

2. Metal halogen lamp: Metal halogen lamp is a popular fish tank lamp before. Its advantages are strong light penetration and good color rendering effect. Because its light is close to sunlight, it will release ultraviolet rays, which can sterilize and protect the health of fish. This kind of lamp is not versatile, so it is used less.

3, LED lamp: LED lamp is the mainstream choice at present, and it has a good prospect. The biggest difference between it and the previous fish tank lamp is that it belongs to the cold light source, so it will not change the water temperature, thus reducing the stimulation to fish. But it is also expensive, so it is not popular.
