Yes, guppies need a heater in their tank. Guppies are tropical fish from South American rivers and lakes with warm water temperatures between 72-82° F (22-28° C).

In-home tanks without a heater, the temperature may fluctuate significantly due to changes in the surrounding environment. This is uncomfortable for your fish and can reduce their lifespan by causing stress.

It’s essential to install a heater in their tank so they can remain comfortably at the optimum temperature range all year round.

Can Guppy Survive Without a Heater?

Guppy Aquarium Heater Size Guide

The aquarium’s size determines its heating capacity. Using small tanks, it is necessary to have a heater of lesser power density. Similar heaters need higher tank size heater wattage to provide sufficient water to be heated correctly.

A simple thumb rule must be followed when selecting a heating power. The rules are approximately 5 watt units per liter. Below is a list of heating wattages needed for saltwater aquariums. The room temperature was deemed 70 degrees Celsius (21 degrees Celsius).

The tank water can be heated according to the aquarium tank size and wattage described earlier.

Guppy Aquarium Heater Size Chart Examples:

  • 2-5 gallons = 25 watts
  • 10-15 gallons = 50 watts
  • 15-20 gallons = 75 watts
  • 20-40 gallons = 100 watts
  • 40-60 gallons = 150 watts
  • 60 or more = 200+ watts.

It is important to note that the heating power should always be calculated accordingly, as too much or little heat can lead to the death of the guppies. Thermometers are recommended to ensure that the ideal water temperature is maintained.
