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.
If you can't get a commercial gecko diet you can feed crested geckos a combination of insect prey items and fruit though it is more difficult to feed a balanced diet this way. The insect portion of the diet can be made up mainly of crickets with the occasional addition of other insects for variety.
