Green iguanas are gorgeous and impressive, but they grow huge — over five feet — and need a custom room-sized enclosure, powerful lighting, and confident handling. They're an advanced, long-term pet that many people sadly underestimate, so they're only for very prepared keepers — and check your local rules first, because some places (Florida among them) no longer allow green iguanas as pets.

Should I get an iguana?
💚 Why you'll love an iguana
- Striking and full of personality
- Allergy-friendly
- Long-lived
- Can become tame with steady work
⚠️ Things to know
- Grow huge — need a room-sized enclosure
- Powerful tail, claws, and a strong bite
- Strict lighting, heat, and diet needs
- Often underestimated — a big commitment
The honest answer: Probably not — that hatchling becomes a five-foot animal needing its own room, and in Florida you legally can't buy one at all.
👍 Get one if…
- You're ready to build a room-sized enclosure
- You checked local law before falling in love
- You're confident handling a strong fifteen-pound adult
👎 Think again if…
- You're in Florida — green iguanas are no longer legal
- You're charmed by the hatchling with no build plan
- You have under-fives — CDC advice, plus tail, claws and bite
- You rent, with no spare room to convert
✅ Am I ready for an iguana?
Wanting one and being ready for one are different questions. These are the ones worth answering honestly before you decide — there are no wrong answers, and a "not yet" is a perfectly good result.
Baby iguanas look small — but adults grow 5–6 FEET long and eventually need a closet-sized (or room-sized!) enclosure. Can your family commit to that?
- Yes — we know and we've planned the space
- We have a big tank, not a room
- SIX FEET?!
If that one gave you pause: Look at photos of adult iguanas next to people, then look at your house with a grown-up. This is the #1 reason iguanas get given up.
Iguanas live 15–20 years and need fresh chopped greens EVERY day (they're vegetarians!). Daily salad duty for two decades?
- Daily salad chef for 20 years — yes
- That's a long time
- Probably not honestly
If that one gave you pause: Practice making a fresh "iguana salad" daily for two weeks — collard greens, squash, no lettuce-only shortcuts!
How to care for your Iguana
Iguana care in depth
That little iguana becomes a five-foot reptile
The green iguana in the pet store is a hatchling — but a healthy adult reaches five to six feet long (mostly tail) and can weigh over 15 pounds. They don't stay small, and they need a correspondingly huge home: most adults require a custom, room-sized enclosure, not an aquarium. Iguanas are one of the most underestimated and surrendered reptiles precisely because people buy the cute baby without planning for the giant adult. Go in expecting to build for the full-grown animal.
Powerful lighting, heat, and a big, strong body
As large tropical reptiles, iguanas need strong UVB across the enclosure, a hot basking spot, high humidity, and climbing branches — all scaled up to a very big space. They're also physically powerful: an adult has a whip-like tail, sharp claws, and a strong bite, and a stressed or poorly socialized iguana can injure someone. Daily calm handling from a young age helps, but adults need an experienced, confident keeper — this is not a pet for young children.
A strictly plant-based diet
Iguanas are herbivores — their diet is entirely leafy greens and vegetables, with no animal protein, since feeding meat or insects damages their kidneys. Getting the calcium and variety right is essential to avoid metabolic bone disease. Combined with a 15–20 year lifespan, the room-sized enclosure, the powerful adult size, and the specialized care, the green iguana is a serious, expert-level, long-term commitment that far too many people take on unprepared.
Green iguanas are big, long-lived lizards — they can reach 5–6 feet and live 15–20 years. They need a lot of space and care, so they're best for dedicated families.
✅ Before you bring an iguana home
🗓️ Your routine — easy chores to remember
- Fresh greens and water
- Check basking temperature and UVB
- Spot-clean droppings
- Some gentle handling to keep them tame
- Deep-clean the enclosure area
- Soak or bathe them as needed
- Check skin and behavior
- Full habitat clean
- Replace UVB bulb every 6–12 months
- Reptile-vet check-up yearly
💰 Monthly cost: Higher: the enclosure alone is a major build, plus lighting and years of care.
