Best Temperature For Guppies

Guppies are definitely some pretty cool aquarium fish, but just like with all other fish, they require certain conditions to survive and thrive. One of the most important things to look out for is the water temperature. Let’s talk about guppies and what is the best temperature for guppies.

So before we dive into temperature let’s take a quick look at the Guppy Fish itself and cover some basics but essential information.

About The Guppy Fish

The guppy is generally considered to be a warm water tropical fish as it resides in countries such as Venezuela and Trinidad. These guys are fairly friendly and do just fine in a community tank of 5 gallons to 10 gallons (more on how many guppies you can house in tanks on this article here). They usually don’t get into fights. The guppy is a fairly small fish, usually never exceeding 2.5 inches in length. The male is a very colorful fish, with a deep yellow and green color scheme. There are also black, blue, red, and silver varieties, but those are fairly rare.

Guppies are also easy to take care of because they will eat pretty much anything that can fit into their mouths. They like the water to be of a medium hardness and fairly neutral in acidity with a pH level of 7.0. A good filtration system and lots of water changes are needed to keep these guys happy and healthy.

So, What Is The Best Temperature For Guppies?

The temperature of the aquarium water is an important thing for most, if not all fish. Guppies require the water to be between 74 and 82 degrees Fahrenheit in the wild. Generally speaking, when it comes to guppies in your aquarium, they seem to do the best in waters ranging from 70 to 80 degrees Fahrenheit.

Now, since they come from countries where temperatures and climates for vary, they can handle some variation here. Guppies can handle water temperatures as low as 63 degrees Fahrenheit and as high as 87 degrees Fahrenheit.

That being said, keeping the water between 74 and 78 degrees Fahrnehiet is probably your best bet when it comes to keeping your guppies happy and healthy. Anything colder than the minimum temperature will result in a slow metabolism, sluggish swimming, and odd behavior.

On the other hand, water that is too hot will also cause behavioral changes, can cause aggression, will increase metabolism way too far, create health issues, and essentially shorten the lifespan of the guppy.
