Depends what type you get. This is a crested gecko, and they're super easy to have.
Don't require any heating, just a nice tank with lots of stuff to climb on. Clean once a week. Replace food every other day. These guys are fruit eaters too, and there is a special mix you get for them that you just mix with water, couldn't be any easier! :D They don't need a lot of attention either, so if your busy and can't get them out that week, it's fine :)
