🏠 Enclosure
One adult: 90 × 50 × 50 cm; enlarge for larger animals. Relative humidity 45–65%, with dry rests, a locally moist refuge and water. Locked enclosure, locked room, protected servicing and separate quarantine of at least 90 days.
🪨 Substrate and furnishings
- Give the snake enough uninterrupted floor length to stretch fully. Secure ventilation mesh, doors and cable entries, checking gaps against the smallest animal present. Place cover in both thermal zones and fix stones against collapse. After quarantine, 5–8 cm of compactable soil mixed with washed sand, with a little leaf litter, can provide firm footing and local moisture. Keep most of the surface dry. Avoid sharp gravel, aromatic wood and inaccessible cavities; paper remains useful for sick animals.
💡 Lighting
- Provide 12–14 hours of visible light in the active season and darkness at night. Keep full shade available. No species-specific UVB optimum is established; if low-level UVB is used, measure exposure and review the arrangement with the veterinarian using the UV-Tool reference. Guard lamps and adjust seasonal day length gradually, in step with the approved winter plan.
🌡️ Temperature
Provisional active-season values; not species tolerance limits. Locality-specific winter planning requires veterinary review.
- Basking spot: 26-29 °C
- Warm zone: 20-24 °C
- Cool zone: 17-21 °C
- Night: 15-19 °C
💧 Humidity and water
Air humidity: 45–65%.
Measure relative humidity near the resting animal, using the table as a provisional band. Keep a slightly moist refuge alongside dry resting surfaces; avoid wetting the whole floor. Ventilation and local moisture are more useful than chasing a single percentage. Supply fresh water continuously in a stable bowl, serviced only after isolation. Persistent poor sheds require a hydration and health review, not forced soaking or peeling.
🪳 Feeding
Verify accepted prey before acquisition: some small High Atlas lines depend on lizards. Established rodent-feeding adults: modest thawed whole prey every 10–14 days provisionally; young animals often 7–10 days. Do not collect wild prey.
☠️ Venom
Any bite is a medical emergency; small size or an apparently dry bite is not reassuring.
Move away and call emergency services. Keep the person still, remove rings and tight items, and support the limb without compression. Do not cut, suck, apply ice or a tourniquet, or delay transport to capture the snake. Agree receiving-hospital and poison-centre arrangements before acquisition; antivenom selection and use belong to clinicians. A product labelled for another Vipera species cannot be assumed effective.
🩺 Health — warning signs
- Watch for appetite loss, abnormal posture, injury, breathing issues, failed shedding or molting, and sustained weight loss.
