Housing & Environment

Yucatán Spiny-tailed Iguanas are active, diurnal lizards that benefit from spacious, well-structured enclosures. Adult males can be territorial and are generally best housed separately.

A suitable enclosure should provide room for movement, climbing and basking, with sturdy branches, rocks and appropriate substrate. Hatchlings may require simpler setups while they establish feeding and drinking habits.

Heating & Lighting

As a diurnal species, appropriate lighting and heating are important. Provide a consistent day-and-night cycle with approximately 10–12 hours of light each day, along with a suitable basking area and UVB lighting.

Humidity & Water

Humidity can generally range from approximately 40–80%, with a more humid hiding area available near the basking zone. Fresh vegetables can contribute to hydration, while additional water should be provided when appropriate, particularly for young animals and females during reproduction.
