Customer service means S E R V I C E. Worst service reps I have ever had to deal with. If there was a negative category they would get a F-for their inability to provide a resolution to the service complaints of the customer.
Leopard geckos feed on insects, such as crickets, earthworms, roaches and meal worms. They prefer to eat live insects, and most refuse to eat dead prey. If keeping leopard geckos in captivity, it is important to feed them a variety of types of insects because their food preferences often change over time.
Sometimes your leopard geckos will want to heat up, other times they will want to be cooler. The best way to heat your gecko enclosure is with an under-the-tank heater. I recommend the Zoo Med Repti Therm U.T.H. These come in various sizes; choose the one appropriate for the size of aquarium you are using.
