Brush-tailed bettongs are solitary, nocturnal marsupials who only come together for courting and mating or if a female has an offspring at their heels. Each slow-moving bettong will spend from dusk until a few hours before dawn foraging for food. In the wild, brush-tailed bettongs consume fungus, which doesn’t contain many valuable nutrients or amino acids. Bacteria at the front of the bettongs’ gastrointestinal tract help break down food, create waste, and continue through the digestive process to the back sections of the stomach and small intestine, creating a balanced diet.
