<strong>Can I add warm water to my betta fish tank?</strong>

You can add warm water to your betta fish tank, providing it has been suitably treated with a water conditioner. If your betta fish is in the tank, you will need to ensure the warm water will not cause a sudden and dramatic change to the overall water temperature, or you will cause temperature shock.

<strong>Maximum temperature for betta fish?</strong>

The maximum temperature that a betta fish prefers is 80° Fahrenheit (26.7° Celsius). The maximum temperature a betta can survive at without getting too stressed or sick is 86° Fahrenheit (30° Celsius). Be aware that warmer water can cause your betta to become overactive and holds less oxygen.
