Guppies are tropical fish, and their origin is in Venezuela, Guyana, northern South America and islands in the Caribbean. These areas belong to tropical and subtropical areas, which meet the classification criteria of tropical fish.

Guppies like to grow in warm water. When cultured artificially, it is necessary to keep the water temperature in a stable range. If conditions permit, a heating rod can be installed to keep the water temperature between 23-28 ℃. But compared with other tropical fish, they can adapt to a wider range of water temperatures. As long as the water temperature is between 18-32 ℃, they can grow normally. However, when the water temperature is lower than 18 ℃ or higher than 32 ℃, they will also have more discomfort.

1. Water temperature: guppies are tropical fish and like higher water temperature. When raising artificially, it is best to keep the water temperature between 23-28 ℃.

2. Water quality: Guppies like weakly alkaline water quality, and it is best for breeders to keep the PH value between 7.2 and 7.4. Usually, water can be changed once every 3-5 days, and the amount of water changed each time can be controlled at one third of the total water volume. If conditions permit, filters can be installed to slow down the deterioration of water quality.

3. Feeding: Guppies have miscellaneous feeding habits. In their infancy, breeders can choose to feed them with animal feed and plant feed. This can speed up their growth and ensure balanced nutrition. When they reach adulthood, they can choose to feed them with synthetic feed and animal feed.
