Common Name: Viper Gecko (Carrot-tail Viper Gecko)
Scientific Name: Hemidactylus imbricatus (formerly Teratolepis fasciata)
Size when shipped: Captive-bred juveniles, approximately 0.5"-0.75" total length depending on age; adult size averages 3–4" (7.5–10 cm).
Lineage: F2s from assorted Captive Bred lifestock acquired from 2020-2022.
In-house testing/treatment performed:
Normal activity and behavior
Beginner to Expert?Beginner-friendly with a Bio Dude twist: excellent for attentive beginners through advanced keepers who are comfortable with small, fast, nocturnal geckos and arid bioactive systems.
SizeMiniature gecko species; adults typically reach 3–4" (7.5–10 cm) total length with a thick, “carrot-shaped” tail.
Biological nicheCrepuscular–nocturnal, terrestrial insectivore from rocky steppe and semi-desert habitats. Prefers tight rock crevices, burrows, and low hides, emerging to hunt small invertebrates at dusk and night.
Native rangeArid and semi-arid regions of Pakistan and surrounding areas, with records extending into Iran and possibly parts of India.
Group vs. Non-groupCan be kept solo, as a pair, or in small harems (one male with multiple females) in appropriately sized enclosures. Do not house adult males together. Mixed groups should be similar in size with plenty of hides and visual barriers.
Terrestrial vs. ArborealHighly terrestrial; adapted to rocky, sandy terrain. They will climb low rock work and hard scape but do not require tall, arboreal enclosures. Rocks are absolutely necessary with this species as is branching and thermo gradients established in the terrarium.
Vivarium size
Single animal: 18" x 18" x 18" or larger.
Pair / small group: 24–30" long footprint and additional floor space. 2' x 2' x 2' is great for a small harem. Set up as an arid or semi-arid bioactive habitat with deep substrate, rock stacks, secure hides, and a humid hide for shedding.
TemperatureCreate a horizontal gradient:
Cool side: ~75–80°F (24–27°C)
Warm side / basking surface: ~85–90°F (29–32°C)
Night drop: ~70–75°F (21–24°C)
Use overhead heat and allow the substrate and stonework to hold warmth, mimicking sun-warmed rock. Avoid sustained temps above the low 90s.
Humidity
General ambient: ~40–60% relative humidity (dry air with localized humidity pockets).
Provide at least one humid hide with moist moss or substrate to aid in shedding.
Good ventilation is important; avoid a constantly wet environment while allowing evening spikes from light misting.
DietObligate insectivores. Offer a rotation of:
Appropriately sized crickets and roaches
Mealworms, superworms (in moderation), and black soldier fly larvae
Occasional soft-bodied treats (waxworms, etc., as rare extras)
All insects should be gut-loaded and dusted with a high-quality calcium and vitamin/mineral supplement on a regular schedule (more frequent dusting for growing juveniles).
