Green Iguana Care Guide

Green iguanas are large, powerful herbivores needing extensive UVB, space, and a strict plant-based diet.

Green iguanas are a 15-20 year commitment that can grow to 5-6 feet. They are strict herbivores — never feed animal protein — and require a large permanent enclosure, T5 HO 10.0 UVB at minimum 6 hours daily, and years of consistent daily handling.

Quick Care Facts

• Diet: Strict herbivore — dark leafy greens only; NO animal protein (kidney failure risk)
• Lifespan: 15-20 years
• Enclosure: Minimum 8x4x6 ft for adults — plan for this from day one
• UVB: T5 HO 10.0 required — replace every 6 months — minimum 6 hrs/day
• Never use compact spiral UVB bulbs
