Leopard Gecko — Tremper Albino

Geographical Origin and Habitat: The leopard gecko is native to the dry, semi-desert regions of Southern Asia, specifically Afghanistan, Pakistan, northwestern India, and parts of Iran. They inhabit rocky clay slopes, dry grasslands, and arid scrublands, avoiding fine shifting sand dunes. They spend the hot daytime hours sheltering in deep rock crevices or cool underground burrows. The "Tremper Albino" was the first albino morph isolated and bred in captivity in 1996 by herpetologist Ron Tremper.

Taxonomy and Genetics: Belonging to the family Eublepharidae. The "Tremper Albino" mutation (often called the Texas Albino) is a simple autosomal recessive trait. This genetic mutation completely prevents the production of black melanin, leaving yellow, orange, pink, and tan pigments intact. Their eyes feature a silver or light pink base color with visible red veins under direct light.

Behavior and Habits: Terrestrial, crepuscular, and nocturnal. They possess an incredibly docile, calm, and handleable temperament, making them one of the most popular reptile pets globally. They communicate using slow tail waving and can vibrate their tail rapidly when excited or hunting.

Morphology: Robust body with a plump tail that serves as a fat storage organ. The livery of the Tremper Albino features a yellow or orange background with light brown, pink, or lavender spots and an absolute absence of black. Adults reach 20-25 cm in length. They have functional moveable eyelids and thin toes lacking adhesive pads. Males have prominent preanal pores and hemipenal bulges.

Terrarium Setup: An enclosure measuring 60x40x40 cm is ideal for a single gecko. The substrate must not be loose sand to prevent fatal intestinal impaction; use slate tiles, paper towels, textured vinyl mat, or dry coco fiber. Provide at least three shelters: one on the warm side, one on the cool side, and a humid hide containing damp sphagnum moss necessary for shedding.

Lighting and Heating: Require a daytime thermal gradient with a hot spot temperature of 30-32°C (86-90°F) (via an under-tank heat mat or overhead ceramic heater regulated by a thermostat) and 24-25°C (75-77°F) on the cool side. Night temperatures can drop to 20°C (68°F). A low-output 2% or 5% UVB light is recommended to prevent bone issues.

Humidity and Hydration: General ambient humidity should be kept low (35-45%). However, the humid hide must remain damp at all times (internal humidity >70%) to ensure successful skin shedding. Provide a shallow dish of fresh dechlorinated water, changed daily, on the cool side.

Feeding and Supplementation: Strictly insectivorous. Feed live crickets, Dubia roaches, locusts, and mealworms, with occasional waxworms or hornworms as treats. Dust insect feeders with pure calcium at every feeding for juveniles, and calcium with vitamin D3 2-3 times a week. Place a small bottle cap filled with pure calcium in the tank.

Compatibility: Males are fiercely territorial and will fight violently if housed together. Females can also show territorial dominance, making individual housing the safest choice to ensure a stress-free life. Never house males and females together unless pairing temporarily for breeding.

Health and Common Diseases: Metabolic Bone Disease (MBD) is the most common health issue, caused by a lack of calcium and vitamin D3. Intestinal impaction is caused by swallowing sand. Retained shed on the toes can lead to tissue necrosis and loss of digits due to constricted blood circulation.
