It is best for parrot fish to turn on the lights for about 2-5 hours every day, but how long to turn on the lights depends on the time they can receive sunlight. Under normal circumstances, parrot fish can receive sufficient natural light, and breeders can choose not to turn on the lights or turn on the lights for about 1-2 hours. If the parrot fish can't receive natural light, it will take a long time to turn on the light, which takes about 3-5 hours a day. Parrot fish are sensitive to light. Under the condition of abundant natural light, breeders need to prepare a hidden place for them, which can make them feel more secure.

The time for parrot fish to turn on the lights can be decided according to their habits. If they are active in the morning, the breeder can choose to turn on the lights in the morning. When adding lights to parrot fish, the breeder should not turn on and off the switch. Because parrot fish are timid, turning on and off the lights frequently may scare them.

In addition to activity, breeders can turn on the lights according to when they eat. Before eating, the breeder can turn on the light first, and wait for the parrot fish to adapt to the light before feeding the food. Turning on the light before feeding can not only improve the activity of parrot fish, but also cultivate their good eating habits. In this way, every time the lights are turned on in the future, they will swim quickly and wait for feeding.
