To keep geckos healthy, it's essential to meet their specific habitat requirements. These include maintaining the right temperature and humidity levels, providing adequate lighting, and creating a suitable enclosure. Geckos need a temperature gradient in their habitat, with a warm basking area and a more relaxed zone. Humidity levels should match their species' natural environment. Proper lighting, including UVB light for some species, helps with calcium absorption. Enclosures should have secure lids, appropriate substrate, hiding spots, and climbing opportunities. Regularly monitoring and adjusting these habitat conditions is crucial for the well-being of your gecko, ensuring they thrive in captivity.
