Recommended Gear
General
Front-opening 120-gallon equivalent enclosure with dual ventilation — meets the 4x2x2 minimum for adult blue tongue skinks. Deep base for substrate depth.
Par38 or BR30 halogen flood bulbs deliver the tight, intense basking spot blue tongue skinks need — 100-110°F surface temps with a natural white spectrum. Far superior to ceramic heat emitters for daytime basking.
T5 HO 12% UVB is the gold standard for blue tongue skinks — provides Ferguson Zone 3 exposure across a wide footprint. Pair with a reflective hood for maximum output.
Cypress mulch holds moisture well for Indonesian subspecies and stays drier for Northern BTS — versatile, safe for burrowing, and easy to spot-clean. 24-quart bag covers a 4x2 footprint at 3-4 inches depth.
Monitors both hot and cool side temps simultaneously with independent alarm thresholds. Essential for dialing in the 100-110°F basking zone and 75-80°F cool side without guessing.
Low-D3 calcium powder for dusting food items 2-3x per week. Designed for animals with strong UVB access — prevents metabolic bone disease without vitamin D3 overdose risk.
Heavy ceramic or resin feeding bowl that won't tip during feeding — important for blue tongue skinks that push and root through their food. Easy to sanitize between meals.
