Under Tank Heaters are an inexpensive and unobtrusive way to heat a small betta bowl or terrarium. They usually heat a small bowl of water by a few degrees – we recommend using in conjunction with a thermometer. They are an ideal 24-hour primary or secondary heat source for tropical or temperate reptilian species. These under tank heaters permanently adhere to your terrarium, forming a solid bond for optimum heat transfer.
- Inexpensive, low wattage heaters
- Excellent secondary heat source
- One year warranty
