Hydor Slim Heater for Bettas, Bowls and Aquariums Review
Perfect Heater for Betta. I have a small 1.5 gallon Betta tank which I needed a heater for but most heaters are way too powerful for such a small tank. This heater is excellent – it only raises the temperature 5 to 10 degrees which is perfect for this size tank. So in the winter when my home temperature is 68 the heater will raise the temperature at a maximum 10 degress which brings the temperature to 78. You can also bury it under the gravel so it remains hidden. Would highly recommend this heater.
