Yes!

Your guppy is vulnerable to a host of potentially fatal issues if exposed to extreme temperature swings.

I suggest the Fluval M Series Heaters if you don't already have one. They aren't the cheapest on the market, but I've had fantastic luck with them in my fish tank. You can rest assured that your fish will be safe with a Fluval aquarium, as this is a highly dependable brand.

Heater I Recommend For Guppies

Heaters should be placed in close proximity to filters for optimal efficiency.

Where Should You Place The Heater?

It could get hotter on one side of the tank than the other if it's not placed near the filter.

The filter will aid in re-circulating the heated water throughout the tank, ensuring a consistent temperature throughout.

Don’t Rely Too Much on the Heaters

Finally, most heaters have a temperature indicator, but you shouldn't solely rely on it. You should also monitor the temperature of your tank with a thermometer. The Marina Floating Thermometer is my go-to thermometer because it's both affordable and dependable.
