Husbandry requirements

Gaboon Viper — origin: Lowland tropical rainforests and wooded areas of sub-Saharan Africa (Central and West Africa). A species of the equatorial forest floor..

Terrarium temperature gradient

Night min20 °C
Cool side23–25 °C
Warm side28–31 °C

A species of equatorial undergrowth: a gentle thermal gradient with no scorching hot spot. A slightly warm spot on the floor (~32 °C max) is acceptable but NO intense basking lamp. Natural night-time drop to ~20-22 °C. Use a thermostat and shield every heat source to prevent burns.

Enclosure (adult)
150 × 75 × 60 cm

Spacious, sturdy and TOTALLY secure terrestrial terrarium (venomous species)

A sedentary but massive species: favour floor area over height. Lockable closures mandatory, a hatch/airlock system and a shift box for maintenance without direct contact. Solid hides and a humid zone. Husbandry reserved for trained keepers, with locatable antivenom and an emergency protocol.

Humidity
60–80 %

A humid tropical-forest atmosphere. Maintain 60-80% with good ventilation to prevent stagnation; humidity peaks are useful during sheds.

Substrate
Coco fibrePotting soil/orchid barkSphagnum moss (humid zones)Leaf litter (enrichment)

A moisture-retaining substrate at a good depth. Avoid any dusty or mouldy substrate. Never feed on loose substrate that could be ingested.

UVB
Optional

Not strictly necessary (a nocturnal undergrowth species); low UVB lighting (Ferguson zone 1, ~2-4%) remains beneficial if provided with hides allowing avoidance. A regular photoperiod is essential.

Water source
Always available

A large bowl of clean water at all times, wide enough for the animal to immerse itself; renew frequently.

Origin
Viperidae

Lowland tropical rainforests and wooded areas of sub-Saharan Africa (Central and West Africa). A species of the equatorial forest floor.

Feeding & health

Diet

Carnivore (rodents) — Appropriately sized rats and mice; rabbit possible for very large adults.

A voracious appetite but a slow metabolism: feed sparingly (a single appropriately sized prey item every ~2-4 weeks depending on age, more spaced out in adults). Excess food quickly leads to obesity. Thawed prey preferably, presented with long tongs at a safe distance.

Breeding
Viviparous

Can produce very large litters (15-60 neonates, exceptionally more). Breeding reserved for specialised facilities: the neonates are fully venomous and dangerous from birth.

Health watch points
  • Obesity (overfeeding relative to the slow metabolism)
  • Respiratory infections (incorrect thermal/humidity parameters)
  • Stomatitis ('mouth rot')
  • Difficult shedding / dysecdysis (insufficient humidity)
  • Internal and external parasites, especially in wild-caught specimens

Frequently asked questions

Answers to the most common questions about keeping the gaboon viper.

How big does an adult Gaboon Viper get?
An adult Gaboon Viper typically measures 0.9–1.8 m (a stocky and very heavy adult, on average 120-150 cm (total length); large specimens > 180 cm, exceptional records > 200 cm. the most massive venomous snake in africa, capable of exceeding 8-10 kg.).
What temperature and humidity does a Gaboon Viper need?
A gradient of roughly 23–25 °C on the cool side to 28–31 °C on the warm side. Humidity 60–80 %.
What does a Gaboon Viper eat?
Carnivore (rodents): Appropriately sized rats and mice; rabbit possible for very large adults..
Is the Gaboon Viper a good reptile for beginners?
Expert level. Reputed to be placid and reluctant to bite ('the sleeping giant'), it nonetheless remains extremely dangerous: its strike is among the fastest and longest known, and it has the longest fangs of any snake (up to 4-5 cm). Its apparent calm leads to a dangerous drop in vigilance. Handle only with a hook and tongs, never by hand. Plan ahead: a lifespan of 15–20 yrs.
