There is a whole lot
to be said on this subject; for most of it, I'll let you use the search function here: try "mixing" and then if your eyes still work try "paludarium".
I will say this: keeping wild caught herps (those toads and lizards are 98% likely to be WC) is not a good idea for casual keepers, regardless of the opinion of someone who makes their money by convincing you otherwise. If you do, at the absolute bare minimum quarantine separately for a few months beforehand and get a fecal sample to an exotics vet.

There are many, many more species that are good captives that are captive bred. I won't recommend any, because you need to be captivated by an animal independently of your simple desire to keep living things in a box. If you don't have any animals in mind that you have a strong interest in keeping, then i think you should just leave them to their own business. An enclosure full of non-animal living things could be very, very rewarding and virtually none of those plants would have been taken from the wild.
