all kinds of geckos
beardies
skinks
corn snakes
sand boas
all kinds of cute scaley things would do fine in that size enclosure. depending on how many you are getting and if you want to fill them right away. you could get a couple trios of bp's and just keep the babies that you make and you will have them full in a couple years. lol im running out of rack space and the wifes threating to make me sell some of my dinkers instead of getting more racks
