American toads are quite peaceful towards one another, but larger animals will nudge others from food, so keep an eye on them at feeding time. The conditions favored by toads are also suited to a number of other interesting creatures, and their diets and temperaments suit them ideally to community terrariums.
Compatible animals include spotted, tiger, marbled, slimy and other terrestrial salamanders (see photo), wood frogs (see photo), gray, barking, green and other native treefrogs and land snails. Assuming that space permits the establishment of a warm basking area (without over-heating the toads), you can also house a number of small reptiles with American toads. I have had kept them with 5-lined skinks, Italian wall lizards, green anoles, DeKay’s (brown) snakes, ring-necked snakes and smooth green snakes. There are other possible toad-companions as well – please write in if you would like more suggestions.
American toads will utilize favored burrows for years on end, with wild individuals documented as remaining within the same territory for over 20 years. If you have a population living nearby, encourage the toads to stay nearby by providing a shallow, easily-exited pool and some retreats in the form of half-buried, inverted clay flower pots. Resident toads will learn to gather at an outdoor light in hopes of an insect meal, and will otherwise delight you with their comings and goings.
We know little about the movements of adult amphibians, but it does seem that American toads are usually found within a limited home range, so one can become quite familiar with the individuals resident in a garden or similar area.
