Holy cow, I just realized that this post was posted a long time ago, like 6 months. With leopard geckos you can keep 2 in a 20 gallon tank. And they are most active at dawn and dusk. They are also really cool when they eat.
Also a little late. But I have always liked the idea of a Uromastyx. Also when I spelled Uromastyx incorrectly the suggestion for the word that the computer though was Burgomaster.
