Iguana question

Hi. My boyfriend and I are considering getting an iguana. What signs should we look for to make sure it's healthy? Also roughly how fast do they become full grown? We're going to do the research before we decide to get him I just wanted to ask.

Hit up this youtube channel and it should cover all of that.

They get big fast so make sure you have a LOT of space for him/her.

They do grow somewhat fast, Its not extremely fast but they will need a pretty large cage within the first year or two. (full size cage)
