A fauna box is part of the basic set-up of terrariums. The boxes, also known as faunariums, are used in many situations as a temporary solution or replacement for reptiles, amphibians, mice, arachnids or insects. For example, a fauna box can serve as a transport box, a quarantine station for sick or injured animals, a container for keeping and/or breeding live foods. Like terrariums, fauna boxes are available in many different sizes.
