Thank you for your question. This tetra fish cannot survive below 20℃. Therefore, I keep the water temperature of this tank at 27℃. To prevent the water temperature from dropping in winter, I use a heater with a thermostat function. To prevent the water temperature from rising in summer, I use a chiller-type cooler.
