Frog: Moss, and wet gravel and rocks. Toad: This is not so straightforward... Some toads are adapted to very dry climates/habitats; some toads are adapted to very wet climates/habitats. You will have to figure out what type/species of toad it is.
Well, all of the big toads would need a lot of room, so all of them would become cannibals and eat each other until one is left. Then that toad would be happy. SO a toad, not toads, could live in a small habitat.
Generally speaking, frogs have slimy skins and prefer moist environments and have long strong hind legs for jumping. Toads ,however, have warty, dry skin and prefer arid habitats and they also have shorter legs designed for walking instead of jumping.
Toads are amphibians of the order Anura, or Frogs. The distinction between a toad and frog is not made in taxonomy but by popular culture. A frog is considered to be a toad based on drier skin and terrestrial habitats.
