The breeding of guppies requires attention to the following aspects:

Water quality and water temperature: Guppies have relatively high requirements for water quality, and maintaining healthy water quality is very important. The pH value of water should be maintained between 7.0 and 8.0, and the water temperature should be kept between 25 and 28 degrees Celsius. When changing water, be careful not to have too much temperature change. The water before changing water should be left to stand for about 3 days in advance, or use an oxygen pump for intense aeration for 1 day before use.
Feeding: Guppies like to eat a variety of foods, including dry feed, frozen food and live food, but ensure the diversity and balanced nutrition of feed. Don't overfeed when feeding, otherwise it will lead to deterioration of water quality and may also make guppies overly obese and affect their health.
Living environment: Guppies need enough space to swim. The size of the aquarium is very important. The density of fish farming should not be too high. Each guppy needs at least 20 to 30 liters of water. There should be appropriate shelters and decorations in the aquarium, such as aquatic plants, rocks or wood roots, to simulate the habitat environment of guppies in nature, which is more conducive to their survival.
Social interaction and health check: Guppies tend to be aggressive in character, especially males. When breeding multiple guppies in the same aquarium, pay attention to the gender ratio and territory arrangement, try to reduce direct competition among male fish and avoid fighting. Regular health checks should also be conducted, and pay attention to the behavioral and appearance changes of guppies, such as swimming style, appetite, condition of scales and fins, etc. Any abnormal signs may be a sign of health problems.
Disease prevention: Guppies are easily affected by some common diseases, such as rotting tail, ich, etc. Regularly checking water quality, reasonable feeding and maintaining an appropriate water temperature can effectively prevent the occurrence of these diseases.
Mixed breeding: Guppies can be mixed with most small tropical fish, such as gold peacock cichlids, zebrafish, neon tetras, bristlenose plecos, corydoras, etc., but they are not suitable for mixed breeding with parrotfish, angelfish and tiger barb fish, because they may attack guppies.
By maintaining good water quality, providing a balanced diet, creating a suitable living environment, paying attention to social needs, conducting regular health checks and preventing common diseases, the survival rate of guppies can be greatly improved and they can grow healthily.
