A tortoise, blue tongue skink, and a bearded dragon.

That is actually a really appealing idea. It’s much more feasible than my idea, and much more interesting to people that know next to nothing about reptiles. The concept of housing reptiles together that are active at different times is much more likely to draw their interest than my idea. Thank you. I’ll look into this further myself.

Do yourself a favor and save some money. Do it in a 55 gallon with green anoles (diurnal) and house geckos (nocturnal). Keep 5 anoles and 5 house geckos. They both eat bugs and I've actually seen them cohabbed successfully before. You can switch out the house geckos for green tree frogs or something if you can't find house geckos.
