What do you feed a long tailed lizard as a pet?

Since you are asking this question, it's best to assume that you know nothing about caring for reptiles. Before you consider food, proper housing, heating, and lighting have to be addressed. Keeping reptiles is similar to keeping fish, in many ways. They require a specialized environment to survive in captivity.

First, you will need a 10 gallon-sized tank or cage, for one animal, or a 20 gallon for a pair or trio. There should be a tight-fitting screen top (or front-opening doors). Substrate can be coco fiber, forest floor, or similar high-humidity bedding. Climbing branches and plants for cover (plenty of them).

Long-tailed lizards (like virtually all reptiles) require controlled heat. An under-tank heat mat or radiant heat panel will do the trick. It should be controlled using a thermostat or rheostat. A digital thermometer with a remote probe should be used to monitor temperatures in the tank. The warm side should be 90F, and the cool side 75 to 80F.

These lizards also require UVB light in captivity, so a fluorescent UVB light should be provided. The tube should be replaced every 6 months, as the UVB coating wears off.

Mist the cage once or twice daily to provide drinking water, and increase humidity.

Feed them 1/4 inch crickets, gut-loaded on quality food, and dusted with a quality calcium powder containing vitamin D3, every other day. Once a week, use a multi-vitamin powder containing preformed vitamin A, instead.

Before purchasing any reptile, do your research to ensure you have the knowledge and means to properly care for it. Buy a book on its care. Never rely on advice from pet store personnel, they rarely have appropriate knowledge of reptile care.
