I just recently moved all my snakes into a rack system and they're doin great. Only problem is now I have empty tanks! I'd like to keep a small lizzard or two in it but can't decide which kind. I like crested geckos but I'm not sure I want something that I have to tend to daily due to a demanding work schedule and family life. I also like some leopard geckos but since it's a 20 tall and not long would it be enough room since they're terrestrial? Haven't done too much research yet on species so I'd like some opinions on the two I mentioned and all the ones I didn't if you have any experience. Thanks to everyone in advance!!
