Angelfish need lighting, but the duration and intensity of the light need to be properly controlled.
Lighting Requirements and Effects
Angelfish need light to boost their physical development and enhance the aesthetic value of the fish tank. If the indoor light is insufficient, you can turn on the lights to supplement the illumination. Under normal circumstances, providing 4 - 5 hours of light per day is sufficient. Also, the light intensity should not be too high. A light tube around 6500K is more suitable. If you need to turn on the light at night, it's best to install a small night light with a soft glow to avoid disturbing the fish.
The Impact of Lighting on Angelfish
The duration and intensity of light have a significant impact on the growth of angelfish. Excessive or overly intense light can affect their rest and physiological activities, so there's no need to keep the lights on 24 hours a day. To mimic the natural environment, you can turn off the lights at night, which is beneficial for the rest and growth of angelfish. In addition, choose warm white, blue, or green lights, and avoid using red or yellow lights, as these colors are not conducive to the growth of angelfish and can easily cause them to get sick.
Requirements for the Rearing Environment of Angelfish
Angelfish are suitable for living in weakly acidic soft water, with the water temperature maintained between 26 and 32 degrees Celsius. They have a gentle temperament, do not attack other fish, and have a strong adaptability. They don't have special requirements for water quality. When it comes to decorating the fish tank, you can take inspiration from the underwater environment in South America and use driftwood and fine soft sand to simulate the natural underwater world.
