Guppy is a tropical fish, because guppy growing in the wild lives in Venezuela, Guyana, Brazil, Caribbean and other regions. The temperature in these areas is relatively high, which belongs to the standard tropical and subtropical areas, so guppies are tropical fish. In addition, although guppy can accept a wide range of temperatures, it also has the ability of cold resistance. But the most suitable temperature for them to live is between 23-28 ℃, which also meets the requirements of tropical fish.

guppies are tropical fish, and the lowest water temperature they can accept is 16 ℃. If the water temperature is lower than 16 ℃, they may die. Even if there are some guppies with strong constitution, they can grow at a low temperature of 16 ℃, but they will get sick and die if they can't persist for too long.

Although guppies can accept a low temperature of 16 ℃, it is best for breeders not to control the temperature within the lowest range. Because in the low temperature environment, not only their appetite and activity will be affected, but also their resistance and immunity will decline. If they grow in a low temperature environment for a long time, their physique and life span will also be affected, and eventually they will die. For artificial breeding of guppies, it is best to keep the water temperature between 23-28 ℃, and it is best to install heating rods to keep the water temperature constant, so that they can live more comfortably.
