The best water temperature for betta fish is around 74-78 Fahrenheit, or 23-25 Celsius. Your betta will generally be fine if the water temperature is slightly out of this range (72-80 F), but 74-78 is what their natural habitat of rice paddies in Thailand and other southeast asian countries contains.lightly warmer water temperature for Betta fish (80-82 F) can be used if your betta is sick and needs to be quarantined or separated from other fish while he is being treated with medication.
Well, Yes and no. Betta do like LIGHT to be able to distinguish night and day, they also need the warmth, but you can use a heater. betta fish do need light, but it is not gooâ¦d to keep a betta in direct sunlight as it may increase the temperature byy far too much. so just keep it in light at day, or get a lamp.
