Temperature & Humidity

Aim for a substrate temperature of 27-32 C. Place the heat source under one third to one half of the enclosure to give a hot spot of 32 C and an ambient of 27 C. Keep relative humidity at a minimum of 50-65 percent. Year-round night-time drops are not necessary for health or for captive breeding.

Enclosure

Adults are fine in the equivalent of 10 to 20 gallons (about 38-76 litres). Being fossorial they need little vertical space and can be kept in shallow plastic tubs. Cover the whole floor with 5-10 cm of sand, wood chip or aspen bedding. Provide a flat-bottomed water bowl 13-18 cm across at all times.

Diet & Feeding

In the wild it constricts birds and small mammals. In captivity offer thawed frozen mice matched to the snake's girth, warmed to about 32 C before feeding. It is an ambush predator that lunges out from under the substrate, so use soft-tipped feeding tongs.

Temperament

Slow-moving, rarely aggressive and easy to handle thanks to its small size. It is active at dusk and at night and spends the day buried. It is not social, so keep it singly outside the breeding season.

Notes

The dorsal keels sharpen towards the rear, so never grip a struggling animal hard. Listed on CITES Appendix II as Boidae spp. since 4 February 1977, recorded in Species+ under the name Gongylophis conicus. Appendix II, so no Japanese registration certificate is required. The IUCN Red List assesses it as Near Threatened.

About Rough-Scaled Sand Boa

A small sand boa native to the dry regions of India and northern Sri Lanka, known for its viper-like zigzag pattern and keeled scales. This burrowing, sand-dwelling species is calm and beginner-friendly.

7 things to know before welcoming a Rough-Scaled Sand Boa

1. 1Needs Deep Burrowing Substrate

   As a fossorial species, provide a soft, deep substrate it can burrow into—vermiculite or reptile-safe sand work well. Shallow substrate can leave it feeling exposed and stressed.

2. 2Rarely Seen During the Day

   This snake spends most daylight hours buried in sand, so don't expect much daytime activity. It's most active around dusk and at feeding time.

3. 3Keep It Dry, With a Warm Spot

   Coming from arid habitats, it doesn't tolerate high humidity well. Keep the enclosure on the dry side with a temperature gradient and a dedicated warm spot, since excess moisture can lead to mold or skin problems.

4. 4Zigzag Pattern Is Mimicry

   The zigzag dorsal pattern is thought to mimic the venomous Russell's viper, helping deter predators. In reality, this species is completely non-venomous and easygoing.

5. 5Calm, Easy-Going Temperament

   True to its beginner-friendly reputation, it rarely bites and tolerates handling well. That said, if startled it may coil defensively, so approach calmly and avoid sudden movements.

6. 6Stays Compact Even as an Adult

   Adults reach at most about 99cm, making this one of the smaller boas you can keep. Its manageable size is part of why it's a popular pick for first-time snake owners.

7. 7Feeds on Small Rodents

   Its staple diet is small rodents such as frozen-thawed mice. Because it's a burrowing species, offering food on or lightly buried in the substrate encourages more natural feeding behavior—just be sure prey size matches the snake's size.

Frequently asked questions about Rough-Scaled Sand Boa

Q.Is this snake suitable for beginners?

A.Yes — it's classified as beginner-friendly and has a calm temperament, making it approachable for first-time snake keepers. That said, it's worth learning its specific care needs, like its preference for dry conditions, before bringing one home.

Q.How big does it get?

A.Adults reach at most about 99cm, making it one of the smaller boa species. This compact size means it doesn't need a huge enclosure.

Q.Is it venomous?

A.No, it's completely non-venomous. Its zigzag pattern resembles the venomous Russell's viper, but this is believed to be mimicry that helps deter predators rather than any actual danger.

Q.Where does it spend its time during the day?

A.Being a fossorial species, it spends most of the day buried in sand. It's typically only visible around dusk, at night, or during feeding.

Q.What substrate should I use?

A.Since it likes to burrow, a soft, deep substrate such as vermiculite or reptile-safe sand works well. As it comes from arid regions, avoid keeping the substrate too moist.
