The lizards don't need to stay together forever. That simply wouldn't be feasible for me. They need to stay together for approximately a year. I'm planning on having them sealed off from each other for a month or two, and having them acclimate to each other a little outside of the cage at first. I'd actually prefer to have smaller reptiles so I can get a smaller cage. They just can't be the same species because I feel that would hurt my project, and make it too simple. The cage will also be bioactive. I'll test it on my snake first to see what problems I run into with that, and then make a similar setup for the reptiles. Until another person responds I'll be looking into smaller species that get along well. Don't worry about being rude. I'm inviting criticism so I don't care. Like I said I really don't know what I'm talking about here so any responses are appreciated.
In that case, the only two species I've read that have been suggested as possibilities for successfully cohabbing were a pink tongue skink and a crested gecko... This was mentioned in the book "Rhacodactylus.." by RepashyVosjoli.

In the book, the authors suggested a single PTS and a single crested gecko in a large planted terrarium with a good chunk of vertical climbing space and lots of "furniture" and hiding spots. These species were suggested because one is diurnal and the other nocturnal. One is mostly terrestrial, the other arboreal, and they both eat small insects or fruit / veg as prey. The idea being, they won't come in contact with each other, won't be awake when the other is awake, and won't occupy the same space in the terrarium. I do not know if the authors actually did this or not.

Honestly, I'm not sure the acclimation you mention will matter. With different species, they won't necessarily "communicate" the same way or understand each other's signals to back off, etc. They can view each other as competition, but not really socially interact. If they have similar needs, they will compete for water, for the best hides, the best heat source spot, etc. Unless you plan on providing a large enough enclosure to have multiple of each of these items, you may be in for trouble and violence (and high vet bills or death). In the case of the 2 species I've suggested above, you'd still want to provide like the biggest exo terra possible (36" x 36" x 18") and have food / water sources for both species separately.
