Rough-Scaled Sand Boa (Eryx conicus) Care Sheet
The Rough-Scaled Sand Boa, also commonly known as Russell’s Sand Boa, is a small to medium-sized, heavy-bodied boa native to parts of South Asia. It is a highly specialised fossorial snake, spending much of its time concealed beneath loose soil, sand and other ground cover.
Unlike the smoother appearance of many other sand boas, Eryx conicus has strongly keeled scales that give the body its characteristic rough texture. Its short tail, wedge-shaped head and powerful body are adaptations for moving through loose substrate.
Captive-bred Rough-Scaled Sand Boas can make fascinating and manageable captives. Their husbandry should reflect their natural burrowing lifestyle, with particular attention paid to substrate depth, temperature gradients, dry but not excessively dehydrating conditions, and controlled feeding.

Natural History
Rough-Scaled Sand Boas occur across parts of the Indian subcontinent and surrounding regions.
They inhabit environments including:
- Dry scrub
- Semi-arid grassland
- Agricultural margins
- Sandy areas
- Loose-soil environments
- Rocky scrubland
They spend substantial periods beneath the surface.
Their powerful bodies allow them to push through loose substrate, while the small head reduces resistance when burrowing.
Individuals may remain almost completely concealed while waiting for suitable prey to pass nearby.
Appearance
Rough-Scaled Sand Boas have short, muscular bodies with strongly keeled scales.
Typical colouration consists of:
- Brown
- Tan
- Reddish-brown
- Greyish-brown
with darker irregular blotches or markings.
This pattern provides excellent camouflage against soil, rocks and dry vegetation.
The underside is generally lighter.
The tail is short and blunt, while the head is relatively small and poorly differentiated from the neck.
Rough-Scaled vs Kenyan Sand Boa
The Rough-Scaled Sand Boa should not be confused with the commonly kept Kenyan Sand Boa (Eryx colubrinus).
Although both are fossorial members of Eryx, they are separate species.
Eryx conicus is particularly distinguished by its:
- Strongly keeled scales
- Rougher body texture
- Different natural distribution
- Characteristic patterning
- Generally larger, robust appearance
Care principles are similar in some respects, but each species should be maintained and bred as a distinct taxon.
Adult Size
Adults commonly reach approximately:
60–90 cm (2–3 ft)
although individual size varies.
Females generally become larger and considerably heavier-bodied than males.
Their relatively short length can be misleading because mature females can become substantial, powerful snakes.
Enclosure size should therefore consider both length and body mass.
Enclosure
For an average adult, approximately:
90 × 45 × 45 cm (3 × 1.5 × 1.5 ft)
provides a practical minimum starting point.
A larger enclosure, such as:
120 × 60 × 60 cm (4 × 2 × 2 ft)
provides considerably greater opportunity for environmental enrichment and is encouraged where practical.
The enclosure should prioritise:
- Floor space
- Deep substrate
- Multiple retreats
- A thermal gradient
- Fresh water
- Secure construction
Excessive height is less important than usable ground area.
Juvenile Enclosures
Juveniles can initially be maintained in smaller secure accommodation.
Provide:
- Appropriate burrowing substrate
- Warm-side retreat
- Cool-side retreat
- Fresh water
- Environmental cover
Even very young animals should be able to bury themselves.
Larger accommodation can be used from an early age provided it contains sufficient cover and is completely escape-proof.
Enclosure Security
Rough-Scaled Sand Boas are strong burrowers and can push against enclosure furnishings and doors.
Check carefully around:
- Doors
- Ventilation
- Cable openings
- Sliding tracks
The enclosure should close securely.
Very young snakes can exploit surprisingly small openings.
Substrate
Suitable substrate is one of the most important aspects of Eryx conicus husbandry.
The snake should be able to completely bury itself.
Suitable options include:
- Reptile-safe soil
- Soil/sand mixtures
- Lignocel
- Aspen
- Other loose, dry burrowing substrates
Where enclosure design allows, provide approximately:
10–15 cm
of substrate, with deeper areas particularly beneficial for larger animals.
Should They Be Kept on Pure Sand?
Despite being called a Sand Boa, Eryx conicus does not require an enclosure consisting entirely of loose sand.
Pure fine sand can:
- Become dusty
- Offer limited structural variation
- Collapse easily around tunnels
- Make feeding management more difficult
A structured soil/sand mixture can provide a more stable and naturalistic burrowing medium.
The substrate should be:
- Loose enough for burrowing
- Predominantly dry
- Clean
- Free from chemicals or fertilisers
Hides
Burrowing does not eliminate the need for conventional retreats.
Provide at least:
- One warm-side hide
- One cool-side hide
Additional cover can include:
- Cork bark
- Low rock-style hides
- Artificial burrows
- Secure flat shelters
The snake should be able to choose between different temperatures without sacrificing security.
Heavy Furnishings
Any heavy rocks or decorations must be positioned securely.
Never place unstable heavy objects loosely on top of deep substrate.
A Sand Boa may tunnel underneath them and cause them to collapse.
Heavy structures should rest securely on the enclosure base or be otherwise installed so that burrowing cannot undermine them.
Temperature & Heating
Provide a clear thermal gradient.
Suitable temperatures are approximately:
Basking/warm surface: 31–33°C
Warm ambient area: approximately 26–29°C
Cooler area: approximately 22–25°C
Night: approximately 20–23°C
The snake must always be able to move away from the warm area.
The entire enclosure should never be maintained at basking temperature.
Heating
Overhead heating can create an effective thermal gradient.
Suitable systems may include appropriately installed:
- Halogen basking lamps
- Deep heat projectors
- Ceramic heat emitters
depending upon enclosure design.
All heating equipment must be appropriately thermostatically controlled.
Internally mounted heating equipment accessible to the snake must be securely guarded.
Surface temperatures should be checked with an infrared thermometer.
Substrate Temperatures
Because Eryx conicus spends substantial periods underground, temperatures should not only be measured at the surface.
Check temperatures:
- At the basking surface
- Within the warm-side substrate
- Within the cool-side substrate
- Inside important retreats
The snake should be able to burrow into cooler conditions.
Heating arrangements that cause the deepest substrate to become the hottest area can prevent normal thermoregulation.
Humidity
Rough-Scaled Sand Boas generally require relatively dry conditions.
A useful general ambient range is approximately:
30–50% relative humidity
with normal fluctuations.
The enclosure should not remain continuously damp.
Good ventilation is important.
A localised humid retreat can be provided during shedding.
Humid Hide
A humid hide can contain:
- Damp sphagnum moss
- Moist coconut fibre
- Another suitable moisture-retaining substrate
The contents should remain moist rather than saturated.
This provides access to increased humidity without raising moisture throughout the entire enclosure.
Check and clean the hide regularly.
Water
Fresh drinking water should be available at all times.
Provide a stable bowl that cannot easily be overturned or buried.
Water should be:
- Changed regularly
- Replaced immediately when contaminated
- Provided in a clean container
A very large soaking container is unnecessary, although individuals may occasionally soak.
Lighting
Provide a consistent day/night cycle.
Approximately:
10–12 hours of light per day
is suitable.
Because this species naturally spends substantial periods beneath the substrate, it must always be able to completely avoid bright lighting.
The enclosure should become genuinely dark at night.
Avoid red, blue or purple nighttime bulbs.
UVB
Low-level UVB can be incorporated into modern husbandry.
A useful exposed basking target may be approximately:
UVI 1–2
with buried areas, shaded retreats and hides providing negligible exposure.
The snake must always be able to regulate its own exposure.
Because Eryx conicus is strongly fossorial, exposure is naturally likely to be intermittent.
Furnishing & Enrichment
Fossorial snakes still benefit from environmental complexity.
Suitable enrichment includes:
- Different substrate depths
- Cork bark
- Secure rocks
- Multiple hides
- Low branches
- Leaf litter in selected areas
- Different substrate textures
- Scent trails
The enclosure should encourage:
- Burrowing
- Exploring
- Ambush behaviour
- Concealment
- Thermoregulation
A barren enclosure containing only substrate and a water bowl provides unnecessarily limited behavioural choice.
Diet
Rough-Scaled Sand Boas are carnivorous constrictors.
Wild prey can include:
- Rodents
- Other small mammals
- Lizards
- Other appropriately sized vertebrates
Their hunting strategy often involves remaining partially or completely concealed before striking passing prey.
Captive-bred animals generally adapt well to appropriately sized rodents.
Captive Diet
Appropriately sized:
- Mice
- Rats where suitable
- Other appropriate whole vertebrate prey
can be used.
Whole prey provides the necessary:
- Protein
- Fat
- Minerals
- Vitamins
- Bone
- Internal organs
Routine calcium or vitamin supplementation is generally unnecessary when appropriate whole prey is provided.
Frozen-Thawed Prey
Appropriately prepared frozen-thawed prey is strongly preferred.
This eliminates the risk of live rodents injuring the snake.
Frozen prey should be:
- Completely thawed
- Appropriately warmed
- Presented using feeding tongs
Never microwave whole frozen prey because uneven heating can create dangerous internal hot spots.
Feeding on Loose Substrate
Avoid allowing large quantities of loose substrate to adhere to wet prey.
Prey can be presented:
- Using feeding tongs
- Above the substrate
- On a clean flat surface within the enclosure
Routine removal to a separate feeding container is generally unnecessary.
Moving the snake for every meal can create avoidable disturbance.
Prey Size
Offer prey appropriate to the size and body condition of the snake.
A meal should create a modest visible swelling rather than extreme distension.
Avoid excessively large prey.
Oversized meals can increase the risk of:
- Regurgitation
- Digestive difficulty
- Injury
Prey size should increase gradually as the animal grows.
Feeding Frequency
Juveniles can generally be fed approximately:
Every 5–7 days
depending upon prey size and growth.
Healthy adults can generally be fed approximately:
Every 10–14 days
with frequency adjusted according to:
- Prey size
- Body condition
- Age
- Activity
- Reproductive status
Large adult females should be monitored carefully for excessive weight gain.
Feeding Response
Rough-Scaled Sand Boas are ambush predators and can strike rapidly from beneath the substrate.
Always establish where the snake is before placing hands into the enclosure.
Use feeding tongs for prey presentation.
Some individuals develop very strong feeding responses.
Hands should be washed after handling rodents or other prey animals.
Obesity
Sand Boas naturally have short, robust bodies, making obesity relatively easy to overlook.
Monitor:
- Body shape
- Muscle tone
- Tail base
- Activity
- Weight trends
A healthy snake should remain muscular rather than excessively rounded.
Feeding should be based upon body condition rather than appetite alone.
Handling
Captive-bred Rough-Scaled Sand Boas are generally manageable, although temperament varies between individuals.
When handling:
- Move calmly
- Support the body
- Avoid tight restraint
- Allow controlled movement
Avoid repeatedly digging up a concealed animal solely for unnecessary handling.
Burrowing is normal behaviour and the snake should be allowed periods without disturbance.
Defensive Behaviour
A defensive individual may:
- Strike
- Attempt to retreat
- Burrow rapidly
- Tighten the body
- Occasionally musk
A strike from beneath the substrate may also represent a feeding response rather than defensive behaviour.
Understanding the animal’s body language reduces unnecessary stress and accidental bites.
Handling After Feeding
Avoid unnecessary handling for approximately:
48 hours after feeding
and longer after particularly substantial meals.
Handling too soon can increase the risk of regurgitation.
Allow the snake to digest undisturbed at appropriate temperatures.
Shedding
Signs of an approaching shed include:
- Dull colouration
- Cloudy or blue eyes
- Reduced activity
- Possible temporary feeding refusal
Fresh water and access to a humid retreat generally support normal shedding.
After shedding, check:
- Eye caps
- Tail tip
- Overall skin
Repeated incomplete shedding indicates that hydration, humidity or general health should be reviewed.
Housing Multiple Snakes
Individual housing is generally recommended.
Rough-Scaled Sand Boas do not require companionship.
Separate housing allows accurate monitoring of:
- Feeding
- Faeces
- Shedding
- Body condition
- Health
It also prevents competition and feeding accidents.
Animals should only be introduced for breeding under controlled conditions.
Health
Potential health concerns include:
- Obesity
- Respiratory infections
- Mouth infections
- Dehydration
- Burns
- Retained shed
- External parasites
- Internal parasites
- Regurgitation
- Reproductive complications
Warning signs include:
- Significant unexplained weight loss
- Persistent refusal to feed
- Repeated regurgitation
- Wheezing
- Open-mouth breathing
- Nasal discharge
- Excessive saliva
- Mouth swelling
- Neurological abnormalities
- Significant behavioural changes
Persistent or serious symptoms require assessment by a suitably experienced reptile/exotic veterinarian.
Respiratory Disease
Respiratory problems can be associated with inappropriate:
- Temperature
- Humidity
- Ventilation
- Hygiene
Possible signs include:
- Wheezing
- Clicking
- Nasal discharge
- Excessive saliva
- Open-mouth breathing
Suspected respiratory disease requires veterinary assessment.
Environmental conditions should also be reviewed.
Quarantine
All newly acquired Rough-Scaled Sand Boas should undergo quarantine away from established reptiles.
During quarantine:
- Record body weight
- Monitor feeding
- Examine faeces
- Check skin
- Monitor breathing
- Check carefully for mites
- Observe behaviour
- Maintain separate equipment
Veterinary faecal testing may be appropriate where an animal’s previous history is uncertain.
Captive-bred animals should be strongly preferred.
Sexing
Adult females are generally larger and more robust than males, but size alone should not be used as definitive sex determination.
Sex may be established using appropriate professional techniques.
Any invasive sexing procedure should be performed by an experienced person.
Incorrect techniques can cause injury.
Reproduction
Rough-Scaled Sand Boas are live-bearing snakes.
Females give birth to live young rather than laying externally incubated eggs.
Breeding should only be attempted with healthy mature animals in appropriate body condition.
Breeding requires knowledge of:
- Accurate sexing
- Sexual maturity
- Seasonal cycling
- Pair introduction
- Courtship
- Pregnancy
- Female nutrition
- Birth
- Neonatal husbandry
Pregnancy
Pregnant females may alter their behaviour and thermoregulation.
They may:
- Spend more time in warm areas
- Change basking behaviour
- Reduce food intake
- Refuse food later in pregnancy
- Become less active
Females must have continuous access to an appropriate thermal gradient.
Unnecessary handling should be minimised during advanced pregnancy.
Birth
Females give birth to live young.
Litter size varies considerably according to:
- Female size
- Age
- Body condition
- Genetics
Breeders should have secure individual accommodation prepared before the expected birth.
The female should be monitored carefully following parturition.
Neonates
Newborn Rough-Scaled Sand Boas require:
- Secure individual accommodation
- Appropriate thermal gradients
- Suitable burrowing substrate
- Small hides
- Fresh water
- Appropriately sized prey
Young animals should be monitored individually for:
- First shed
- Feeding
- Body weight
- Defecation
- Normal development
Some neonates may require patience before establishing regular feeding.
Responsible Breeding
Breeding should be undertaken with a clear plan for the resulting offspring.
Breeders should maintain accurate records including:
- Parent identification
- Pairing dates
- Birth date
- Litter size
- Sex where established
- Feeding records
- Genetic information where applicable
Only healthy animals in appropriate body condition should be bred.
Responsible Sourcing
Captive-bred Rough-Scaled Sand Boas should be strongly preferred.
Before acquiring an animal, establish where possible:
- Captive-bred status
- Age
- Sex
- Feeding history
- Health history
- Genetic information
A healthy captive-bred animal with an established feeding history is preferable to an animal of uncertain origin.
Responsible Ownership
Rough-Scaled Sand Boas can live for 15–20 years or longer with appropriate care.
Before acquiring one, consider:
- Long lifespan
- Burrowing requirements
- Appropriate substrate depth
- Whole-prey feeding
- Adult enclosure requirements
- Specialist veterinary care
- Long-term commitment
Their fossorial nature should never be used as justification for keeping them in extremely small or barren accommodation.
A well-designed enclosure allows the snake to burrow while also providing different temperatures, retreats, textures and opportunities for exploration.
Never release a captive snake into the wild.
Summary
The Rough-Scaled Sand Boa is a distinctive, robust and highly specialised fossorial boa whose unusual keeled scales and burrowing behaviour make it a fascinating species to maintain.
Successful husbandry depends upon providing a secure terrestrial enclosure, deep suitable substrate, multiple retreats, an appropriate thermal gradient, predominantly dry conditions, fresh water, environmental enrichment and correctly sized whole prey.
Captive-bred individuals can make manageable and rewarding snakes when their natural burrowing behaviour is properly accommodated.
With appropriate feeding, environmental complexity and responsible long-term care, Eryx conicus can thrive in captivity for many years.
