Appropriate Sun Exposure
Baby guppies can be exposed to the sun in moderation, but attention should be paid to the duration and intensity. Appropriate sunlight is beneficial for the growth of baby guppies. It can boost metabolism, enhance vitality, and make their body colors more vivid. However, excessive sun exposure can have adverse effects on baby guppies, potentially leading to poor growth or even causing diseases.

Advantages and Disadvantages of Sun Exposure
Advantages
Appropriate sunlight can assist baby guppies in synthesizing pigments, making their body colors more gorgeous. Meanwhile, the ultraviolet rays in sunlight can kill the bacteria in the fish tank and prevent the occurrence of diseases.
Disadvantages
Direct exposure to overly strong sunlight or long - term illumination can harm baby guppies, possibly resulting in poor growth or even death. Therefore, under artificial breeding conditions, it is necessary to reasonably control the illumination time and intensity to avoid unnecessary harm to baby guppies.
Control of Sun Exposure Time and Intensity
Time
Providing 1 - 2 hours of illumination per day is more appropriate. It is best not to exceed 5 hours. Avoid direct sun exposure during the strong sunlight hours at noon.
Intensity
The sunlight should be soft diffused light rather than intense direct sunlight. You can adjust the light intensity by using a sunshade net or placing the fish tank in a shaded area.
Other Maintenance Suggestions
Water Temperature
Guppies are tropical fish, and the suitable water temperature is between 24 - 28 degrees Celsius. Too high or too low water temperature will affect their health.
Water Quality
Keep the water quality clean. Use equipment such as filters and oxygenators to clean up the waste in the fish tank and breeding pond.
Feed
Provide feed rich in protein, vitamins, and trace elements. You can use artificial feed and natural feed such as broad beans and green vegetables.
Aquatic Plants
An appropriate amount of aquatic plants helps to increase oxygen, lower the temperature, and enhance the beauty of the fish tank. At the same time, they provide the oxygen and nutrients needed for the growth of baby guppies.
