Favorable Water Temperature For Betta

Any water temperature between 76 and 80-degree Fahrenheit is good enough for Betta.

Heating The water

Whether to heat the water for your Betta entirely depends on your room temperature.

Some individuals won’t have to heat it because the heat from the lights and the central heating is similar to that of the tropical.

But if your home is pretty cold, then it’s advisable to invest in a small-sized water heater for that purpose. Be on the lookout to avoid overheating. This also includes going through the heater specifications to ensure it doesn’t produce too much heat.
