Description
Water. Wild guppies prefer pH levels of 7.0 to 8.0, but commercially-bred guppies can handle pH levels between 6.0 and 9.0. They're also comfortable in temperatures between 70 and 82°F (21.1 and 27.8°C), but their temperature should not drop below 59°F (15°C) or exceed 102°F (39°C), as this will likely lead to death
