Description

Hemitheconyx caudicinctus is a terrestrial West African gecko associated with savannas and sheltered retreats. Its brown body carries pale and dark bands, sometimes with a white dorsal stripe. It has movable eyelids and a thick storage tail; observations in Ghana recorded use of ground burrows and increased activity on nights following rain.

Lifespan15–20 years, sometimes longer

Behaviour

Observe the individual’s behaviour and limit handling.

Housing together

House animals individually because conflicts can occur between females too. Each animal must be able to use its shelter and food without surrendering them to another. Manage breeding introductions separately.

Enclosure and climate

Provide a warm hide, a cool hide and an enclosed humid hide on the cool side, over a drainable digging substrate. Keep the humid hide available when the air is drier: it offers a local moisture choice without wetting the entire enclosure.

Night: 22–25 °C. Warm-season values; keep these without a cool cycle below six months.

Setup

Use a humid hide with a removable lid to inspect and replace bedding. Keep moisture inside it without wetting the surrounding floor.

Warm area, cool area and hides

If heating is specified, place it at one end and distribute hides between that area and the cool side. Choose openings and internal space suitable for the body; after adding bedding, check that entrances remain clear. Set the dish on a stable base and leave routes between retreats; use low supports only where suitable for the species.

Testing and access

Connect specified heat sources to compatible thermostats and guard against contact. Secure probes according to device instructions; measure air at resting sites and heated surfaces separately with independent instruments. In housing with water, also check water temperature and quality: one zone’s thermostat does not control the others.

With the complete enclosure running, record day and night readings and compare them with the sheet. Test doors, cable openings and cleaning access, keeping vents clear. Change one variable at a time and recheck after each adjustment.

Lighting and UVB

Ferguson zone not assigned with sufficient precision to this taxon.

One UVI peak is not verified for this entry. Adjusting the installation requires a target for the identified species and origin; the layout should provide screened areas and voluntary light access. A missing number does not establish that UVB is useless.

UVB is recommended at an intensity appropriate to the species, with the option to withdraw from the light. Evidence of its necessity varies between animals: assess exposure alongside diet and species identification.

UVA is recommended as part of daytime lighting, including when UVB has not been shown to be indispensable. Check the UVB source’s spectrum, as it may already emit UVA: a second lamp is not automatically necessary.

Linear UVB tube with reflector, sized once species UVI is established; no single verified percentage for this entry.

For maintenance, a cycle of approximately 12 hours of light and 12 hours of darkness can serve as an initial reference. Use a timer to switch lights off at night, and keep retreats available so the animal can withdraw from light during the day. Adapt day length to species and origin, following the specific guidance for seasonal care and breeding.

Example with height 45 cm and animal height 17 cm. Not to scale: distances describe layout without guaranteeing UVI or a safe clearance for every lamp. Check the model used, mesh and all reachable points.

Light in the animal’s daily life

Available guidance assigns two different peaks to this species: do not average them. Provide opaque retreats and optional access to low UVB; establish a commissioning target before installation.

An example layout in the enclosure

To make the layout concrete, take housing measuring 90 × 45 × 45 cm, using the first dimensional configuration in the sheet. This is a mounting example: retain the conditions and any alternatives attached to the stated minimum.

In a wooden enclosure with internal lighting, imagine the tube 40 cm above the floor and the back or head at 17 cm. The geometric distance is therefore 23 cm. The branch or platform lies below animal height, according to body size. Place lighting over one side, with a route to fully screened retreats.

In a glass enclosure with a mesh roof, retain the same animal height and imagine the tube 5 cm above the mesh: distance becomes 33 cm. Mesh attenuates UV variably; ordinary glass roofs block UVB. Increasing the percentage alone is insufficient: measure beneath the mesh and adjust height, output or layout as needed.

These distances describe the example, not a safe clearance for every lamp. First establish a verified UVI target for the identified taxon. Also respect the minimum clearance specified for the model used. Recheck with furnishings, guards and mesh installed, including the highest reachable points and animal growth.

Choosing and checking lighting

First define the patch that should illuminate the whole body and the route to a screened retreat. For a broad patch, select a linear tube with reflector; consider a compact only if its useful patch covers the body and leaves an accessible gradient. Check model, output, reflector and mounting distance, then compare measured UVI with the species target. Label UVB percentage alone cannot determine distance and intensity.

The decisive check uses a UVI meter facing the source at animal height. Check the centre and edges of the exposed patch, the highest supports and retreats, which must allow withdrawal from UV. Repeat after moving equipment, changing lamps and plant growth. Without a meter, use the manufacturer’s instructions and measurements for the exact configuration, including safety clearances.

When UVB or UVA are absent

When keeping without UVB, D3 must be supplied through a complete diet or species-appropriate supplementation. Calcium alone does not replace D3. Check existing amounts in prepared diets and multivitamins before combining products; dosage also depends on diet and cannot be derived from lighting hours.

UVA contributes to environmental perception and behaviour and cannot be replaced by vitamins or calcium. A reptile UVB source normally also emits UVA: check its declared spectrum. If the existing lighting lacks it, complete the installation with a suitable source; an ordinary white LED does not guarantee UVA and a UVA-only lamp does not provide UVB.

Humidity and ventilation

During the warm season, maintain daytime humidity at 70–80% and allow it to rise at night. During the cool season, the reference is about 50% by day and 70–75% at night. Measure near hides without letting the hygrometer touch wet bedding, and also inspect substrate beneath retreats. If readings stay outside the specified values, check blocked vents and standing water before adjusting water input; recheck after the change.

Feeding

Terrestrial insectivore: offer moving prey at dusk. Adjust energy using both tail and trunk; do not add waxworms simply to increase weight.

Recommended foods

The tiers describe dietary use: rotate foods within each tier rather than treating them as an absolute nutritional score.

FoodDietary roleBenefits and limitsPreparation
Crickets and locustsMain choicesSupply protein and encourage hunting; calcium is low relative to phosphorus, so preparation and supplementation are needed.Use captive-bred insects and gut-load them as described below. Select suitably sized feeders, place the meal’s batch in a clean container and apply a thin calcium coating immediately before offering them.
Feeder roachesMain choicesThese feeders provide a useful second protein source for rotation, but do not constitute a complete diet or replace calcium supplementation.Offer well-fed soft nymphs sized to the mouth; avoid excessively hard adults.
Silkworms and black soldier fly larvaeFor rotationDiversify texture and nutrients. Black soldier fly larvae can supply more calcium, but content depends on rearing: they do not make the entire diet complete.Choose appropriately sized feeder larvae. Keep silkworms on their specific food; check the supplier’s supplementation guidance.
Waxworms, mealworms and superwormsOccasionalFat-rich larvae concentrate energy and often contain little calcium: use as a small part of variety, not the sole food.Replace part of the meal instead of adding them to a full ration. Avoid hard or oversized larvae for small animals.
Wild insects, fireflies and contaminated preyAvoid / not a stapleMay carry pesticides, parasites or toxins; a healthy appearance does not establish safety.Use traceable feeder cultures; do not collect insects beside roads or treated gardens.

Comparable nutritional values

Protein, fat, calcium and phosphorus are percentages of dry matter, excluding water; dry matter itself is a percentage of fresh weight. These are reference analytical values compiled in a clinical table, not guaranteed contents of your batch or a universal ranking. Age, rearing, feeding and supplementation change composition. Do not compare them directly with fresh-food percentages or already diluted prepared diets. Comparable numbers are not provided for other foods.

DM = dry matter. Ca:P describes calcium relative to phosphorus before supplementation: a protein-rich feeder may still be calcium-poor. Offered portions remain those for this species and life stage.

Meals by age and size

Stage and sizeFrequencyAmount per meal
Young: from first feeding until growth is well establishedDailyInitial trial portion: 3–5 small insects, one at a time. Count those eaten in about 5 minutes; stop when interest wanes rather than continually refilling. Adjust the count to actual prey size and growth.
Juveniles and subadults: still growing noticeablyEvery 1–2 daysInitial trial portion: 3–5 small insects, one at a time. Count those eaten in about 5 minutes; stop when interest wanes rather than continually refilling. Adjust the count to actual prey size and growth.
Adults: near final size, growth has slowedEvery 3–5 days, according to reserves and activityInitial trial portion: 3–5 small insects, one at a time. Count those eaten in about 5 minutes; stop when interest wanes rather than continually refilling. Adjust the count to actual prey size and growth.

Adjusting portions

To assess the portion, compare the amount and type of food eaten with growth and body condition. Weekly weighing of juveniles and monthly weighing of adults helps follow the trend. Adjust the ration gradually when growth or reserves require it; reduce it if body condition indicates excess weight or leftovers remain. Investigate unexpected weight loss or abnormal swelling rather than addressing it only with more or less food.

Preparing and offering meals

Prepare insects during the 24–48 hours before feeding: keep them in their culture container with a complete feeder diet and safe hydration. Check access to food and water and remove spoiled leftovers. Then select feeders of the specified size and prepare only the batch to be offered. This step, called gut-loading, improves prey quality; bran or potato alone do not correct deficiencies.

At feeding time the prey should be easy to swallow. As an initial guide, choose insects no wider than the space between the eyes, then adapt size to the mouth and the animal’s response. Offering them individually or in an escape-resistant dish lets you see actual intake and remove leftovers.

Trial amounts are a starting point for a healthy, active animal at correct temperatures: record intake and weight trend, then adjust the ration. Do not feed again merely because it continues striking at prey.

Calcium and vitamins

Immediately before feeding, lightly coat low-calcium insects with phosphorus-free calcium: they should remain visible, without clumps. Common insects often have an unfavourable calcium:phosphorus balance; rotating them alone does not correct it.

Choose one supplementation programme: plain calcium for ordinary meals and a species-appropriate multivitamin at its labelled feeding intervals. Record the product and its existing D3 and vitamin A; do not add a second dose to meals using a combined product. With measured UVB, agree the oral D3 provision; product concentrations are not interchangeable.

Daily care

First days

Keep retreats accessible and observe without opening them to look for the animal. Check climate readings from outside, offer scheduled food and record actual intake. Prepare the scales and container before weighing so the transfer stays brief; compare weight with earlier records rather than relying on appearance alone.

Cleaning

Keep animals and equipment away from kitchens and food areas, use tools dedicated to each enclosure and wash your hands with soap and running water after handling animals, food, tank water or furnishings. Quarantine new arrivals separately and agree the duration and checks with a veterinarian before introducing them to established animals.

Handling

Before a transfer, prepare an open container and an access route. Allow the animal to enter where possible; if support is necessary, support its body without gripping the tail and minimise time out of the enclosure. Stop repeated attempts to grasp it and allow withdrawal to a retreat.

Checks

Record weight, appetite and behaviour; consult a veterinarian experienced with the species if changes persist. For laboured breathing or wounds, contact them promptly without waiting for symptoms to persist.

Breeding

Sex, maturity and readiness

Check V-shaped pores as well as the tail-base bulge, which alone can mislead. A cautious breeding reference is at least 18 months and about 40–45 g, together with good condition and tail reserves.

Start a record for each breeding animal with identity, origin, documented age and previous weights. Compare the weight trend with growth and body condition; delay introductions for animals still growing rapidly, losing weight or recently acquired. Use stated ages as guidance alongside these checks. If sex cannot be identified reliably, obtain assessment by qualified personnel before pairing.

Preparation and seasonal cycle

Breeding follows recovery from a drier, cooler season. Make gradual changes while retaining a humid hide; resume feeding only when the gradient permits normal digestion. Males court with tail vibrations; separate a female that lashes at or bites him.

Before encounters, prepare and test offspring enclosures and have first foods available. Check records for regular adult feeding and good body condition, then verify access from exposed areas to retreats. If the species protocol includes seasonal changes, adjust settings gradually and record the response. Record night-time air, surface and egg temperatures separately, noting where each is measured. Keep water available throughout preparation.

Courtship and mating

Introduce only identified, compatible adults, with another enclosure ready. Observe from a distance and end the encounter if you observe persistent pursuit, injuries or an animal unable to move away from its partner; do not forcibly separate animals during copulation. Record the date, both identities and what you actually saw: courtship, contact or mating alone does not prove fertilisation.

Before laying and the nest

Offer a moist box with diggable fibre: the first clutch often follows mating by 2–4 weeks, usually with two eggs. Shedding, reduced appetite and digging may precede it. Retain the nest for later clutches without automatically repeating pairings.

Maintain a suitable laying site even without a male: females can produce unfertilised eggs. Persistent straining without laying, weakness or tissue protruding from the vent require prompt veterinary assessment. Do not wait for a predicted laying date if these signs appear. Do not squeeze the abdomen, pull eggs or give drugs to induce laying without veterinary direction.

Egg incubation

Use containers outside the terrarium, moist substrate and a probe at shell level. This guide does not assign a definite duration to one temperature because reviewed data do not support it; do not automatically transfer the leopard-gecko temperature-sex curve.

Test the system before laying with an independent probe at egg height. Use clean, labelled containers, closed but allowing air exchange, with room for eggs and hatchlings. Keep eggs in their original orientation and do not detach eggs glued to their support. The substrate should retain moisture without free water on the shell; check condensation and water loss, adding water at the edge of the substrate rather than onto eggs. Record temperature and events daily without needless opening. The stated times are approximate: do not increase heat to meet a date.

First meals and juvenile care

Rear on paper with a moist hide and dry shelter. After the first shed offer a few supplemented crickets or small roaches daily and check tails, droppings and feeding. Keep hatchlings apart from adults and promptly address sibling competition.

During the first weeks, monitor each youngster: a feeding group does not guarantee that every individual eats. Record intake, droppings and weight at regular intervals to follow growth and adapt housing and food size. Provide separate accommodation if competition prevents an individual from feeding or size differences become marked. Document repeated independent meals before transfer to another keeper.

Female recovery

After reproduction provide water and the usual balanced diet, initially in manageable portions; monitor weight, activity and return of appetite. Keep supplements and lighting consistent with the feeding guide. Avoid further introductions until the previous condition has recovered; later clutches may occur without another mating. Persistent straining, weakness or protruding tissue require veterinary attention, without squeezing the abdomen.

Equipment and example diary

Place the nest where it can be checked without dismantling the enclosure. Label containers with female identity and laying date and prepare the specified medium; for attached eggs, instead provide guards in place without detaching them. If using an incubator, install a thermostat and independent probe and test it before laying. Run offspring enclosures too and prepare scales and first food, reserving capacity for later clutches.

A consistent diary using actual dates helps follow reproduction in Hemitheconyx caudicinctus. Start with adult identity, weight and condition, then record observed encounters, laying or birth and development conditions. After emergence record the first meal actually accepted and each youngster’s growth while continuing to follow female recovery. Over time these records help identify your lineage’s pattern without turning approximate durations into deadlines.
