Frequently asked questions
How big do green anoles get?
5-8 inches including tail. Among the smallest popular pet lizards.

5-7 years in captivity. Shorter than leopard geckos (15-20 years) or crested geckos (15-20 years).
Can green anoles change color?
Yes — between bright green and brown, depending on temperature, stress, and mood. Not as dramatic as chameleons.
Are green anoles good first pets?
Yes for low budgets and small spaces, but the short lifespan and limited handling tolerance push us toward leopard geckos or crested geckos instead.
