How warm should and iguanas tank be?

An iguana's tank should have a temperature gradient, with a basking area ranging from 95°F to 100°F (35°C to 38°C) and a cooler side around 75°F to 85°F (24°C to 29°C). It's essential to maintain proper humidity levels between 60% and 80% as well. Using a thermometer and hygrometer will help ensure these conditions are met for your iguana's health and well-being.
