A leopard gecko tank is the single most important purchase you will make for this species, because it sets the boundaries for temperature gradients, humidity, hide placement, and safe movement. Leopard geckos are ground-dwelling, crepuscular lizards that need horizontal floor space far more than height. As a vet who treats reptiles, I see most husbandry problems trace back to enclosures that are too small, too humid, or impossible to clean without stressing the animal.
When choosing a tank, prioritize floor footprint over gallons on the label, a secure lid or front-opening door to prevent escapes, and enough length to build a warm side and a cool side. Good ventilation keeps humidity in the safe 30 to 40 percent range, while front access lowers stress during feeding and spot cleaning. Match the enclosure to an adult’s needs from the start so you are not rehousing a settled animal later.
