But I would like to point out one can set up vivariums of many species. It just requires a very large enclosure, match the environment of the animals, and consist of species from the same ecosystem. Plus one needs extensive knowledge on the behavior, breeding, and diet of the various animals. It is possible, but one just needs enough cash and knowledge haha. One of these days I would love to set up a 55-100 gallon vivarium consisting of frogs, fish, and what have you. But if you want to get a day gecko go with a giant day gecko - they are the hardiest of the genus. Also very beautiful and diurnal which is always a plus.
