Ok, so I currently have a leopard gecko and love him, but I want a new species of gecko/lizard. I just want one that can maybe climb or is just cool. Bt one that doesnt get to big, like can live in 30 gallon or less, and where can I buy the animal(site). Any suggestions, also how much would the entire setup cost as well,thanks!

P.S. The lizard/gecko doesnt have to be one that clibs, there just cool=)
