Hello from texas!

That setup actually looks good for the fire belly. The only thing I would add would be a rock in the water so the toad could have a resting spot and still be in the water. The tree frogs will need enclosures with height and lot of branches and big leafy plants. They also just need a water bowl to soak it. It should be shallow. Why don't you post some pictures of them..maybe we can help you to identify them so that we can provide the proper advice for their care. They are a little more picky when it comes to temp and humidity requirements than the fire bellies.

I usually suggest 10 gallon tanks for fire-bellied toads, but I also suggest more than just one. They're fun to watch in a group. I agree with Cheri about land for the toad.

If the treefrogs are the same species, they can be in the same tank, but otherwise you'll need two. Once we see pics, we'll definitely be able to help.
