New addition ideas?!

So my girlfriend is awesome and bought me a huge 40 gallon breeder tank from the dollar a gallon sale at petco, I almost broke my toe with it moving it off my bed at 6am when I got off work haha

Anyways!! I was going to move my bp into and get a new family member for her 15g tank. so I stuck the appropriate sized uth on it and then when I saw it sitting there, being huge in my room I started to think my little bp would be alright in his 15 gallon tank for a while longer and that something else
Would be cool in the 40 =P

I really want this aqua iguana I saw the other day! It's about 12 inches right now but I'm wondering how long it will fit in the 40 for. Also I was thinking savanna monitor but again... How long till i have to dedicate a room to that huge lizard lol

I would get a red tail or something but my girlfriend and my mom would team up and kill me so the possibilities are limited to lizards...

Any ideas guys??

Or non boa/python snakes =P something that can't kill my moms miniature pincher hahaha

Bearded Dragons are awesome!!!

I was thinking that too but I'm kind of leaning to the tropical side lol

Well I've pretty much got my heart set on a savannah monitor now lol they have the cute little baby ones at the reptile shop and it was epic watching one chase down a cricket.

Ive done my research but what I can't seem to find is how quickly they grow.... How much time do you think I have to build a giant cage before the little guy out grows the 40 gallon?

Savannah Monitors grow extremely fast within the first year or so.
They go from being under a foot long to being around 3 or 4 feet within the first year or two [depending if you have a female (smaller) or a male (larger) and if they are kept in proper conditions]. Unfortunately, that 40 gallon would not last you long at all.
