The guppy is a typical tropical fish. Tropical fish in the natural environment are often bathed in the sun, which helps them grow and develop. Therefore, guppies are not afraid of sunlight. And it often swims in the upper layer of the water, the appropriate time of sunlight can make its color more bright. In addition, ultraviolet rays in the sun can kill bacteria in the water, play a role in disinfection, which is conducive to the healthy growth of fish.
But in the summer, it is best not to put it in the sun. In summer, the temperature is very high and the sunshine is very strong. At this time, if it is exposed to light, it is easy to sunburn the fish. It will also raise the temperature in the fish tank and cause the fish to lack oxygen. But in other seasons, the guppies like the sunshine very much.
For guppies, light is very important. Use fluorescent lamps or aquarium lights to provide it with light, it is not afraid. But not with a bright light, which would frighten them. Installing an aquarium lamp with scattered light can make the fish grow better. But at night, it needs to rest and can't turn on the light. If the lights are on at night, they will be grumpy and run around. Therefore, aquarium lights can only be used during the day and can not be turned on at night.
