Green Iguana

Scientific Name:Iguana iguana
Lifespan: Over 30 years
Size: 4-6 feet long w/ tail
Handling Ease:Fair to Good


  • An iguana’s diet should consist of:
    • 80% fresh veggies (refer to 700-40), fed daily
    • 15% fresh fruit (refer to 700-40), fed daily
    • All food should be dusted with calcium powder/vitamin powder (alternating days)

Caging & Environment

  • A minimum of a 20" high tank with screen cover OR a screen enclosure for babies.10 gallon tanks are not recommended because they do not provide the adequate thermal gradient. Due to the large adult size of this animal, a custom enclosure for adults is highly recommended.
  • Reptile Bark substrate
  • 75w Basking Light with fixture (or a light that will provide a basking temperature of 95°- 100°)
  • 5.0 Compact Fluorescent UVB light with fixture
  • Lots of artificial plants/vines
  • Lots of branches or stable climbing platform
  • Large Water bowl (large enough to soak in)
  • Food bowl
  • Calcium & Vitamin Powders (used alternately)
  • Spray bottle for misting
  • Iguanas should be misted at least twice daily.


  • Iguanas are a long-term commitment, but can be easily tamed into a good pet.
  • They are easy to care for due to their herbivorous nature.
  • Although iguanas rarely bite, adult iguanas have very sharp nails and may scratch you just from holding on for support.
  • Males will generally get larger than females. They can be sexed accurately at about 24” in length.
  • Iguanas can be housed individually or in sexed pairs, provided that the enclosure is adequately sized. Adult males will fight.
  • If housed as sexed pairs, iguanas will breed readily in captivity.
