Its really easy to do safely with research, I'm just annoyed at how many people on the Internet give opinions without having done anything similar. With a little bit of research you can easily set up a comminal cohabitating tank. Combining many type of frogs is a bad idea, a white's would eat a green tree frog as well as a firebelly toad but it would likely pick up toxins from the toad. If you do set up a tank with other species try sticking to one frog type or at least choose 2 different types that occupy different areas of the tank (ground level terrestrial frog and an arboreal for example, that way food competition and territory battles don't concur as much / or much at all if your tank is large enough with many hiding spots. Obviously more animals means a lot larger space, the larger the space the less conflict you risk.

I see you point on toxins more clearly, and I agree with your statement, I just feel a tiny bit of research would Easily let someone know if an animal is toxic to another.

The lab and cheetah have quite a bit to do with it really, It's an example of interspecie cohabitation and how animals can go outside their normal family for companionship. They wereb inteoduced as birth and are rhe same age, no surrogacy there. I'll admit most amphibians / reptiles don't have nearly the same drive for companionship as mammals, but I'd you think my bearded dragon hasn't bonded to me and doesn't enjoy being held and played with well then I say you've either never owned one or didn't treat it right. Reptiles can and do form bonds with their owners, to varying degrees depending upon species.

Yes, I do realize that green tree frogs, white's tree frogs, anoles, and goodness knows what else can have very similar basic terrarium requirements. The problem, especially with frogs, is the stress level. Even species that live side-by-side in the wild don't truly cohabit; they have a very unique niche that they exploit. Just because two frogs could potentially live on the same tree in the wild does not mean that they should be put into the same tank in captivity. Additionally most frogs are not social animals, and are certainly not sociable with other species in confined spaces. The behavioral stress from being in the presence of another species constantly is unhealthy and could cause a frog to become sick.

The few times I have seen cohabiting of species work out well is in areas warm enough for people to let larger reptiles roam a yard year-round. Even then, each individual (or at least each species group) typically has its own special housing and feeding area designed for its specific needs.

Going on to the point that I made about the toxins; it is not just for feeding. That is just the most clear-cut example I could think of. Why would a frog native to North America have any sort of tolerance for the chemicals present on an Australian frog's skin? They wouldn't. Since frogs absorb chemicals very easily through their skin, this could cause major issues.

Your example about the cheetah and dog has nothing to do with reptile husbandry. Those two were put together either for companionship or the lab was used as a surrogate. The reason the cheetah doesn't attack the dog for not acting like another cheetah is because it has an emotional attachment to the dog (and also because the cheetah is well fed). Reptiles don't form 'emotional attachments'. There's a reason people 'play with' their dog and 'handle' their snakes. I don't care how long you house different species together, the second one of them moves like food or makes a 'threatening' gesture (different species might see different gestures as threats) there will be a fight.
