An incandescent bulb or basking light in a reflector type fixture should be placed at one end of the aquarium to
provide heat. For a 10 gallon aquarium a 40 to 60 watt bulb should provide an adequate temperature of 70°F - 74°F.
Ideally, for the absorption and utilization of calcium, a fluorescent reptile bulb should be placed on top of the
aquarium.
