I always thought they preferred it warmer; most sources say 25 - 28 degrees.N0body Of The Goat said:I'd say a tank with at least a 75x30cm footprint, heavily planted, with the heater set at 22C (if the water gets warmer to ~27C because of sunlight/ ambient temp during the summer, they will be fine).
