The temperature of the betta fish tank should be maintained between 22 and 30 degrees.
Bettas are tropical ornamental fish, and the optimal growth temperature is between 25 and 27 degrees. Since bettas have strong adaptability and can adapt to lower temperatures even in places with slightly lower winter temperatures, it is recommended to maintain the temperature between 22 and 30 degrees for the best health.
Fish are poikilothermic animals. When the temperature is low, their metabolism slows down, their activity decreases, and they are prone to getting sick. Therefore, maintaining an appropriate water temperature is very important for the health and vitality of bettas.
