What is a good pet gecko or lizard with a lifespan of 15 years or less?

I looked into Bearded Dragons, Leos, Gargoyle Geckos, African Fat-tailed geckos, Day Geckos, House Geckos, White lined geckos(skunk geckos), Curly Tailed lizards, Crested Geckos, Skinks, Monitors, Anoles, and many more. Crocodile geckos (or Moorish geckos) seem good but i don't know their life span. Don't want to large of a pet, able to fit in a 30g or less would be nice, and i would like to be able to hold them. Thanks.
