Map fish are tropical fish, and light is very important for map fish. If you can't provide enough light for the map fish, you need to use lights to make up for the light time. Lighting can not only simulate the sun's rays, accelerate the growth rate of map fish, increase the brightness of the skin color of map fish, but also improve the ornamental effect of map fish.
Map fish need at least two hours of sunlight a day. If the fish tank has enough light time, there is no need for additional light irradiation. If the fish tank is in a place where the light is not enough, it is necessary to use light irradiation to complete the light time. The time that map fish receives light every day should be controlled within 6-8 hours, not too long.
Map fish every day to receive 6-8 hours of light time can be. Provide plenty of light during the day, and do not turn on the lights at night. Because the light will make the map fish excited, if the light is not turned off at night, the map fish will always be excited, and eventually lead to exhaustion. Therefore, the map fish does not need to turn on the lights at night. Let the map fish get enough rest at night. Only in this way can the map fish grow healthily.
