A small, burrowing, orange-and-brown sand boa that spends most of its life submerged in substrate, ambushing prey from below. Its tiny footprint, docile nature, and simple dry husbandry make it a top beginner snake.

Part of the Boas
Boas are mostly non-venomous constrictors that give live birth, ranging from small sand boas to giant boa constrictors; many are popular, long-lived pets valued for calm temperaments.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Adult enclosure
3 × 1.5 × 1 ft (≈ 20-gal long)
Kenyan sand boas are small (2–3 ft) ambush burrowers. Minimum is a 3×1.5 with at least 4 in of fine sand or eco-earth for burrowing, basking 32 °C, cool 24 °C, low humidity.

Recommended
Larger deep-substrate viv
4 × 1.5 × 1 ft, 6 in substrate
A 4×1.5 with 6 in+ of fine substrate, scattered hides, and a strong thermal gradient. Sand boas spend most of their lives buried — substrate depth is welfare-critical.

Ideal
Naturalistic arid enclosure
4 × 2 × 1 ft, naturalistic
Naturalistic East African arid enclosure with deep mixed substrate, hardscape, and varied basking. Lets the snake choose burrow depth and thermoregulate fully.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg / Neonate
Most reptiles lay leathery- or hard-shelled eggs incubated by ambient warmth, though some snakes and lizards give live birth. Incubation temperature can influence sex and development in many species.
Photo coming soon
Hatchling
Hatchlings emerge as fully formed miniatures of the adult, often using an egg tooth to slit the shell. They are independent from birth but small and vulnerable, and may show brighter or different juvenile patterning.
Photo coming soon
Juvenile
Juveniles grow steadily, shedding their skin periodically as they enlarge. Coloration and proportions shift toward the adult form, and growth rate depends heavily on temperature, diet, and basking/UVB access.
Adult
Adults reach the species' full length and mass and become sexually mature. Many reptiles show sex differences in size, coloration, or features (such as larger heads, hemipenal bulges, or femoral pores), and continue to shed throughout life.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Because they spend nearly all their time buried, sand boas need floor space rather than height; a single adult is well housed in a 10-20 gallon enclosure or a 24 x 16 in tub. The substrate is the centerpiece: provide 3-4 in of aspen, play sand, or a sand-soil mix deep enough for full burrowing. A secure lid is important even though they are not strong climbers. A small water bowl and one above-ground hide round out the setup.
Maintain a warm side of 90-95 F (32-35 C) at the substrate surface, a cool side around 78-80 F (26-27 C), and nighttime in the low 70s F. Belly heat from an under-tank heater on a thermostat works well for these subterranean ambush predators. Keep humidity low, around 30-40%; excess moisture causes health problems. UVB is not required.
Substrate
Provide deep (3-5 in) loose, fine aspen shavings or a play-sand/soil mix so this fossorial boa can burrow and ambush from beneath the surface; aspen is a popular, clean choice. Avoid cedar/pine, and keep the substrate dry to prevent scale rot.
Equipment & setup
A simple, secure 10-20 gallon tank suits an adult; provide a belly-heat gradient with an under-tank heater on a thermostat giving a warm side of 90-95F and a cool side in the high 70s. No UVB is required for this nocturnal burrower; offer a small water dish (they often stay buried) and keep humidity low.
Diet
Kenyan sand boas eat appropriately sized frozen-thawed mice, from pinkies for hatchlings to adult mice for large females (males eat noticeably less). Feed every 5-7 days for juveniles and every 7-14 days for adults, sizing prey to the snake's girth.
They are classic ambush feeders that strike from beneath the sand and constrict, so dangling thawed prey with tongs near the surface usually triggers a fast response. Avoid loose-sand impaction risk by feeding on a tile, in a separate container, or by ensuring prey is fully thawed and dry.
Behavior & temperament
Sand boas are extremely docile, almost never bite, and are content to be briefly handled before they try to burrow back down. They are fossorial and reclusive by nature, so seeing them out is uncommon, which suits keepers who want a low-maintenance display animal rather than a frequently held pet.
Enrichment is mostly about deep, diggable substrate that lets them express natural burrowing and ambush behavior. Keep handling short and gentle; their main stressor is being denied a place to hide rather than handling aggression.
Health
Most health issues trace to husbandry that is too wet or too cool: respiratory infections, scale rot, and stuck sheds. Keep the enclosure dry and warm with proper belly heat. Retained eye caps can occur with low humidity at shed time and may need a brief humid hide.
Impaction from ingesting loose sand is a possibility during feeding, so many keepers feed off-substrate. Obesity from overfeeding small males is common. Standard reptile hygiene applies to limit Salmonella, and any wheezing or open-mouth breathing warrants a reptile vet visit.
Tips, DIY & hacks
Use an under-tank heater rather than an overhead lamp, since this species absorbs warmth through the belly while buried and overhead heat dries the air too much. Feed appropriately sized rodents (often offered with tongs at the surface), keep the dish small to avoid raising humidity, and provide a buried hide; these hardy, slow-moving boas are great low-maintenance keepers.
