Common collared lizard

This profile covers Crotaphytus collaris. Other collared-lizard species, sexes and localities differ in size and colour.

Confirm the exact locality; collared-lizard forms do not all share one climate plan.

Plan a bright, spacious running habitat and a dependable varied insect supply.

Arrange dependable holiday care and keep money available for food, replacement equipment and appropriate veterinary help. Test the habitat before the animal arrives.

Wildform proposes 120 × 60 × 60 cm or larger for one adult, exceeding the guide’s smaller 91 × 46 × 46 cm example. Secure rocks before adding diggable substrate.

Measure usable internal space after substrate, guards and furnishings. Check ventilation, cable holes and access against the smallest occupant. Fix heavy furnishings independently of loose substrate.

ReptiFiles proposes a 40–48°C basking surface, 25–32°C cool side and 20–26°C at night. The surface figure is not enclosure air. Confirm the exact C. collaris locality and preserve cooler refuge choice.

Record the warm and cool locations, overnight minimum and daytime maximum. Air, surface and substrate readings are different measurements. Any added heater needs compatible thermostatic control and safe separation from the animal; assess summer cooling as well as winter heating.

Use the cited exact-species husbandry evidence to agree the measured climate.

The genus guide proposes basking UVI 4–6, bright daytime illumination and complete shade. Measure at the animal’s back beneath the actual mesh. This is a source proposal; check it against the measured installation.

Keep the night dark and provide retreat from daytime light. Lamp percentage, electrical wattage and a product name cannot establish the exposure reaching an animal. Check the finished installation after changes to mesh, branches or lamp position.

Agree UV exposure for the exact locality and installation.

The guide differentiates drier western collared lizards from eastern animals using about 50–70% air humidity. Do not apply its below-40% western recommendation to every C. collaris. Provide drinking water and a separately maintained humid refuge; resolve the locality before choosing the cycle.

Inspect the occupied refuge and substrate as well as the air reading. Adjust water provision and ventilation together, and clean contaminated drinking surfaces. A single humidity number cannot describe every microclimate.

Offer varied, appropriately sized cultured invertebrates and a reviewed supplementation plan. Remove uneaten insects rather than leaving prey to bite a resting animal.

Record what is actually eaten and follow changes in growth and body condition. Food size, life stage and the full diet matter. Supplement products require an individual plan; do not combine calcium, vitamin D and multivitamins by guesswork.

House singly for this plan. Provide room for fast movement and avoid chasing or tail restraint.

Make necessary maintenance predictable and allow voluntary retreat. Prepare a secure transfer container before essential moves. Observation should not repeatedly interrupt feeding, rest or moulting.

Watch locomotion, body condition and egg-laying behaviour. Repeated falls, weakness or persistent straining need veterinary assessment.

Keep dated observations of appetite, activity and condition. A sudden decline, injury, abnormal breathing or repeated failed moults needs appropriate professional assessment. This guide does not provide a diagnosis or medicine dose.

Obtain documented captive-bred C. collaris; do not use an imported wild animal as a routine first choice.

Ask for a dated source record, scientific identity, life stage and established care history. Keep new arrivals and their equipment separate while an appropriate quarantine plan is agreed. Check current official rules for the exact animal, route and transaction before importing or buying; this page does not establish legal clearance. Never release animals or viable eggs outdoors.

Check safe basking access, water and food intake. Inspect rock supports, usable running space and UV exposure after any furnishing change. Keep a dated record of measurements and observations, and revisit the full advice when conditions or life stage change.
