I'd love one, but at the moment I simply couldn't take on something that would grow to that size - even though I expect it would take a long time to reach those kind of proportions.
Are there any reptiles which follow a similar diet to that of a green iguana / rock iguana and also stay small?
How small is small?
The Fiji Iguana pictured earlier in one of my posts is fully grown - They eat mainly green leaves and fruit, although they do appreciate the occasional bug as well. They are CITIES article 10 listed though so subject to strict controls. Also very expensive. I am trying to breed mine at the moment as I was lucky enough to come across a female.
I am a member over at the RFUK forum which is a great source of info and a good place for research.
Chinese water dragon I see mentioned above - I also have pair of these - They can potentially get VERY large - Not to the extent of the green Iggy, but should not be purchased if you are looking for something that will surely stay "small". Also they do not predominantly eat greens (I assume this a requirement due to not wanting to keep live food in the house?) - They mostly eat bugs, so wouldn't fit the bill there either.
Bearded dragons do eat bugs as well, but the diet should be mainly greens. They are relatively easy to keep and of course very easy to purchase, given they are massively over bred - There are literally THOUSANDS in rescue that you could look to home.
Off the top of my head I can not think of one single species that stays "small" and eats 100% greens and fruit. I will have a think and let you know if I can think of anything
