Can the animals go down to the water?
I'm glad to hear you took the toads out. The problems with reptiles and frogs are the aggressive behavior feeding for the frogs and the timid behavior of lizards. The tree frogs will out compete the geckos and could hunt the crickets you leave in the setup without the geckos getting any. Usually keeping this type of tree frog is hard alone to do and it's probably the one species many keepers can agree along with the Dumpy Tree Frogs that should be single species at least until you have kept them a few years. They are more dependent on precise climate like temp humidity and so on. The gecko could most likely be wild and give disease to your frogs and could be fatal. I'm not trying to be negative I just don't want any animals to cause harm on the others and nobody telling you there are things to look out for.
Generally keeping multiple species together is something that needs to be researched and it's best to own the species individually that you want to bring together so you can see what they prefer in your experience and the biggest reason is so you don't favor one over the other. A lot of times people attempt to mix animals but only want to have something live with their favorite species. Where as a keeper who has both and knows how to care for them and can accommodate both will have more success and will be able to truly have a successful mixed species setup. It's something that should take a lot of time because it's bringing two species together understanding diseases, behavior, prey size, climate, cohabitation and more. It is something that can really be rewarding if done with proper research and planning. I like your ambition and I think you have some cool ideas I just believe there is a lot of reason to slow down the process and take time enjoying the toads and tree frogs and whatever you have. Then begin asking questions on here and finding articles and videos on one and possibly both species.
I mean no disrespect or any negative criticism. Your setup looks great!
