Strange Batrachians

The most commonly kept frogs are the poison arrow frogs, the mantellas, the treefrogs, clawed frogs and the horned frogs. A few other species (tomato frogs, leaf frogs, etc.) are usually available. Larger and more active frogs (bullfrogs and kin) require more space than most hobbyists have available, but they can make interesting inhabitants for greenhouses and the like. Toads are also available, though only a few species are colorful enough to attract most hobbyist's attention. (More recently, I've seen a few albino Woodhouse's toads, which are fairly interesting.) Fire-belly toads are probably the most common.
