Eastern Collared Lizard (Crotaphytus collaris)
A.K.A. Common Collared Lizard
Eastern Collared Lizards are medium-sized lizards ranging from tan to green to yellow and have a dark band around their necks that gives them their name. They will grow up to 8-14 inches long. Males have well-defined white spots over their bodies which are much fainter on females. These lizards can live up to 10 years if taken care of properly.
Habitat and Tank Requirements:
This species is native to the deserts of Western North America.
These lizards do well with sand or sand/gravel mix as a substrate. Be sure to put enough rocks and wood in the tank for your lizard to hide in and climb on.
Eastern Collared Lizards need at least a 20 gallon tank for a pair (two males should not be kept together, as they may fight). A screen cover is recommended for your tank, as it allows better airflow and heating.
A comfortable temperature for these lizards is around 70-80º F during the day and nighttime temperatures between 60-70º F. LEDs or other low-wattage light bulbs work best for maintaining these temperatures.
In addition to UV light, these lizards need a hotter basking area from 95-100º F. You can use either a ceramic heat emitter or a reptile basking light for this. Heat rocks are not recommended as they can burn your animal.
Your tank should have a small, shallow bowl of water that is cleaned daily. This is for your lizard to drink from as well as wade in. Some lizards wont drink from a bowl. In this case some sort of dropper is recommended.
Eastern Collared Lizards will feed on small crickets, fruit flies, mealworms, wax worms, and any other insect small enough for them to ingest. Adults will appreciate an occasional pinkie mouse as well. It is recommended that food be dusted with calcium to prevent bone softening.
Allow your lizard time to become accustomed to its new home before handling them extensively. Handling them little by little over a period of time lets the animal get used to you and reduces stress.
