guppy is a tropical fish and likes a higher water temperature. However, they can accept a wide range of temperatures. As long as the water temperature is between 15 and 38 ℃, they can grow normally. When raising artificially, it is best to use a heating rod to keep the water temperature between 22-24 ℃. In this temperature range, the growth rate and state of guppy are the best, and their physique will become stronger and stronger.

Guppy likes weakly alkaline water quality, and breeders can keep the PH value between 7.2 and 7.4. However, they can also adapt to neutral water. If the water quality cannot be well controlled, the PH value can be kept at about 7.0. As long as the water quality does not become weakly acidic, guppies can live normally.

Breeders can add some small stones to the water, which can separate minerals and keep the water quality stable. You can also add some baking soda and big soda to the water, which can make the water become weakly alkaline. The requirements of guppy on water quality are not strict. Breeders only need to change water once every 3-5 days, and the amount of water change each time is controlled at one third of the total water quantity. Before changing water, it is best to expose yourself to the sun for 2-3 days, which can not only adjust the temperature difference between new water and old water to be consistent, but also eliminate chlorine in water and avoid the impact of chlorine on the health of guppy.
