African Red-Sided Skink (Trachylepis homalocephala) Care Sheet
The African Red-Sided Skink (Trachylepis homalocephala) is an attractive, active African skink characterised by a streamlined body, smooth glossy scales and, in many individuals, striking reddish or orange colouration along the flanks.
It is a diurnal, sun-exposing skink, so successful captive husbandry should provide much more than warmth alone. A suitable enclosure combines usable floor space, climbing and basking structures, a strong thermal gradient, appropriate UVB, bright visible lighting, secure cover and a varied invertebrate-rich diet.
These skinks can be fast and alert. Although individuals may become accustomed to routine keeper activity, they are generally better regarded as active display animals than reptiles that need frequent handling.
Captive-bred animals should be preferred whenever available.

Taxonomy
The species belongs to the large African skink genus:
Trachylepis
Older literature concerning African skinks may use the genus:
Mabuya
for species now placed within Trachylepis.
Accurate scientific identification is important because many superficially similar African skinks have historically appeared in the pet trade under inconsistent common names.
Natural Distribution
Trachylepis homalocephala is associated primarily with southern Africa.
Animals occur in environments where they can make use of:
- Sun-exposed ground
- Rocks
- Logs
- Vegetation
- Crevices
- Sheltered retreats
Natural Habitat
Habitat can include:
- Savannah
- Open woodland
- Scrub
- Rocky terrain
- Coastal vegetation
- Areas containing fallen timber and natural cover
The species uses both the ground and raised surfaces.
This should influence enclosure design.
Appearance
African Red-Sided Skinks possess:
- Smooth glossy scales
- A streamlined body
- Strong functional limbs
- Long tail
- Relatively pointed head
Colour
Colour varies between individuals, populations, age and sex.
Animals may show combinations of:
- Brown
- Bronze
- Olive
- Grey
- Cream
- Orange
- Red
The reddish or orange flank colour gives rise to the common name.
Adult Size
Adults generally reach approximately:
20–30 cm total length
with a significant proportion consisting of tail.
Behaviour
Normal behaviour can include:
- Basking
- Rapid movement
- Foraging
- Climbing
- Investigating crevices
- Hiding beneath cover
- Watching activity outside the enclosure
Activity
This is a:
day-active species.
A healthy animal should have opportunities to become visibly active during the illuminated part of the day.
Temperament
Individuals can be:
- Alert
- Fast
- Shy
- Curious
Some become confident around routine keeper activity.
Handling
Frequent handling is unnecessary.
When handling is required:
- Support the body
- Keep the animal close to a safe surface
- Do not squeeze
- Never grab the tail
Tail Autotomy
Like many skinks, the tail may be shed as a defensive response.
A regenerated tail may differ from the original in:
- Shape
- Scale pattern
- Colour
Escape Risk
These skinks can move quickly.
Ensure that:
- Doors close securely
- Cable openings are sealed
- Ventilation openings cannot be exploited
Take particular care when servicing the enclosure.
Enclosure Size
For one adult, approximately:
90 × 45 × 60 cm
should be regarded as a practical minimum.
However:
120 × 60 × 60 cm or larger
is strongly preferred.
Why More Height Than a Burrowing Skink?
Unlike highly fossorial species, Red-Sided Skinks readily make use of:
- Rocks
- Logs
- Branches
- Raised basking platforms
Moderate enclosure height therefore increases usable space.
Floor Space Still Matters
Do not replace floor area with height.
The enclosure should provide both:
good floor space + usable low-level climbing structure.
Juveniles
Juveniles can be maintained in appropriately furnished larger accommodation provided:
- Food can be located easily
- Numerous small hides are available
- Temperatures are correct
- Escape security is excellent
Substrate
A naturalistic substrate can contain:
- Organic topsoil
- Washed play sand
- Clay-containing soil
- Leaf litter
Substrate Depth
Approximately:
10–15 cm
is useful across much of the enclosure.
Deeper areas can be provided.
Digging
Although not as specialised for burrowing as Sandfish or Peter’s Banded Skinks, Red-Sided Skinks should still be able to:
- Dig
- Investigate soil
- Shelter beneath cover
Moisture Gradient
The exposed surface can remain relatively dry.
Lower substrate and protected areas can retain slightly more moisture.
Hides
Provide multiple secure retreats.
Include:
- Warm hide
- Cool hide
- More humid retreat
Cork
Cork bark is particularly useful for creating:
- Crevices
- Elevated surfaces
- Hides
- Climbing opportunities
Rocks
Secure rocks can create excellent:
- Basking surfaces
- Visual barriers
- Crevices
Rock Safety
Heavy rocks should be supported securely.
Do not balance heavy stone on loose substrate.
Branches
Provide sturdy branches or logs positioned:
- Horizontally
- Diagonally
- Near the basking area
Plants
Safe live or artificial plants can provide:
- Visual cover
- Shade
- Environmental complexity
Enrichment
Useful enrichment includes:
- Live-prey hunting
- Leaf litter
- Food searching
- Different substrate textures
- Multiple basking levels
- Logs
- Scent exploration
Temperature Gradient
Provide a clear daytime thermal gradient.
Basking Surface
Aim approximately for:
38–42°C
on the principal basking surface.
Warm Ambient Temperature
Maintain the warmer side around:
27–30°C
during the day.
Cool Area
Provide a cooler area around:
22–25°C
Night Temperature
Temperatures can generally fall to approximately:
18–22°C
overnight for healthy animals.
Basking Surface Is Not Air Temperature
A basking rock measuring:
40°C
does not mean the enclosure air should be 40°C.
You are creating:
hot surface → warm zone → cooler zone → sheltered retreat
Heating
Use overhead heating.
Suitable options include:
- Halogen flood lamp
- Appropriate incandescent basking flood
Why Overhead Heating?
This better recreates daytime solar heating and creates a naturally useful:
warm-above / cooler-below
gradient.
Basking Area
The basking zone should be broad enough to warm most of the animal’s body.
Avoid an extremely concentrated hot spot.
Heat Safety
Internally mounted heat lamps must be appropriately guarded.
Thermostat
Heating equipment should be controlled appropriately while temperatures are checked independently.
Measuring Temperatures
Use:
digital thermometers
for air temperatures.
Use an:
infrared thermometer
for basking surfaces.
UVB
Appropriate UVB is an important part of comprehensive long-term husbandry.
African Red-Sided Skinks are:
diurnal and sun-exposing
and should be provided with the opportunity to regulate their UV exposure.
Target UVI
At the main basking position, aim approximately for:
UVI 3–4
with progressively lower exposure elsewhere.
What Is UVI?
UVI means Ultraviolet Index.
It tells us how much biologically effective ultraviolet radiation actually reaches the animal at a particular position.
Why Is UVI More Useful Than Lamp Percentage?
Because a UVB tube labelled:
6%, 7%, 12% or 14%
does not tell us by itself how much UV reaches the skink.
Actual exposure changes with:
- Distance
- Reflector
- Mesh
- Lamp model
- Lamp age
- Height of the basking surface
UV Gradient
A useful enclosure should provide approximately:
Main basking area: UVI 3–4
Surrounding illuminated area: UVI 1–2
Partial shade: UVI below 1
Deep hide: approaching UVI 0
Why Provide Shade?
A reptile requiring UVB does not need UV everywhere.
Wild reptiles regulate exposure by moving between:
sun → partial shade → deep shade → shelter
The enclosure should allow the same choice.
What UVB Lamp Do I Actually Need?
For most adult setups, look for a:
LINEAR T5 UVB SYSTEM
rather than relying on a small compact UVB bulb.
Depending upon:
- Enclosure height
- Mesh
- Lamp mounting
- Basking height
a system somewhere in the:
6–12% UVB class
may be appropriate.
The correct system is whichever safely provides approximately:
UVI 3–4 at the basking position.
Why Such a Wide 6–12% Range?
Because installation changes everything.
For example, a lower-output lamp:
mounted relatively close inside an enclosure
can sometimes provide similar exposure to a stronger lamp:
mounted farther away above mesh.
This is why we specify the UVI target.
What This Means in Practice
If you’re at the expo or reptile shop and don’t understand the lamp percentages, ask for:
a good-quality linear T5 UVB system suitable for a moderately high-UV, day-active skink.
Explain that you are aiming for:
UVI 3–4 at the basking position.
Then use the manufacturer’s current distance chart for that exact lamp.
Do I Need the Strongest Desert Tube?
No.
Do not automatically buy the strongest lamp available simply because the animal comes from Africa.
The objective is:
correct exposure
not maximum exposure.
Heat and UVB Should Overlap
Position the main UVB coverage over the same general area as the basking heat.
The primary basking site should therefore provide:
HEAT + BRIGHT LIGHT + UVB
Shade
Elsewhere, the animal should be able to access:
lower UV → partial shade → complete shade.
Mesh
Mesh between the lamp and animal can reduce UV output.
Always account for mesh when selecting lamp strength and distance.
UV Meter
An appropriate UV Index meter provides the most reliable way to check exposure.
Measure at approximately:
the height of the skink’s back while basking.
If You Don’t Own a UV Meter
Most new keepers won’t.
Use:
- A reputable T5 system
- Manufacturer distance guidance
- Correct basking height
- Plenty of shade
UVB Replacement
Replace the UVB lamp according to the manufacturer’s current guidance.
A UVB lamp may continue producing visible light even after useful UV output has declined.
Visible Lighting
Bright visible daytime lighting is strongly recommended.
An additional daylight LED can improve:
- Activity
- Circadian rhythm
- Natural behaviour
- Enclosure visibility
Photoperiod
Approximately:
11–13 hours of daylight
is appropriate through much of the active season.
Seasonal adjustment can be provided.
Night Lighting
The enclosure should become:
dark at night.
Do not use visible:
- Red
- Blue
- Purple
night bulbs.
Humidity
Humidity should be provided as a:
gradient
rather than attempting to maintain one exact percentage everywhere.
Ambient Humidity
Approximately:
40–60%
is suitable across much of the enclosure.
Humid Retreat
Provide access to a more humid hide or sheltered microclimate.
This is particularly useful during:
- Shedding
- Dry environmental conditions
Ventilation
Good ventilation remains essential.
The enclosure should not remain:
- Saturated
- Stagnant
- Permanently wet
Misting
Occasional light misting can be used where required to support:
- Humidity
- Drinking behaviour
- Plant maintenance
Allow exposed surfaces to dry appropriately.
Water
Provide fresh clean water continuously.
Water Bowl
Use a:
- Stable
- Easily accessible
- Appropriately shallow
water bowl.
Diet
African Red-Sided Skinks should receive a diet based primarily around:
varied invertebrate prey
with appropriate additional foods where accepted.
Suitable Invertebrates
Offer a rotation including:
- Locusts
- Crickets
- Roaches
- Black soldier fly larvae
- Silkworms
- Mealworms
- Appropriate beetle larvae
- Earthworms from safe sources
- Captive-produced snails
Variety Matters
Do not feed only:
crickets
or:
mealworms
for the animal’s entire life.
Gut Loading
Feeder insects should be properly gut-loaded for approximately:
24–48 hours
before feeding.
High-Fat Feeders
Foods such as:
- Waxworms
- Large quantities of superworms
should be offered sparingly.
Plant Foods
Some Trachylepis will accept limited plant matter.
Suitable foods to trial can include:
- Appropriate leafy greens
- Squash
- Edible flowers
These should complement rather than replace the primarily invertebrate-based diet.
Fruit
Small amounts of suitable fruit may be accepted.
Fruit should remain:
occasional
rather than a dietary staple.
Vertebrate Foods
There is no need to make rodents a routine part of the diet.
An occasional appropriately sized whole vertebrate food may be accepted by a large adult, but an invertebrate-rich diet is more appropriate as the normal foundation.
Calcium
Invertebrate prey should receive appropriate:
calcium supplementation.
Vitamin D3
Where effective UVB is correctly provided, additional dietary vitamin D3 should generally be used sparingly according to the overall supplementation programme.
Multivitamin
Use a suitable reptile multivitamin periodically.
Juvenile Feeding
Growing juveniles can generally receive appropriately sized prey:
daily or near-daily
depending upon:
- Meal size
- Growth
- Body condition
Adult Feeding
Healthy adults can generally receive food approximately:
3–4 times per week
with quantity adjusted according to:
- Activity
- Meal size
- Body condition
- Season
Obesity
Do not assume that constant willingness to eat means the animal requires more food.
Monitor:
- Body shape
- Weight
- Activity
Feeding Enrichment
Encourage natural foraging by:
- Releasing suitable insects
- Hiding prey beneath leaf litter
- Varying feeding locations
- Allowing scent-driven searching
Social Housing
Individual housing is the safest general recommendation.
Can They Be Kept Together?
Experienced keepers may maintain compatible animals in sufficiently large enclosures.
However, cohabitation can introduce:
- Territorial competition
- Feeding competition
- Basking competition
- Reproductive pressure
- Injury
Males
Mature males should not automatically be housed together.
Monitoring Groups
If animals are cohabited, monitor:
- Weight
- Feeding
- Basking access
- Hiding behaviour
- Chasing
- Injuries
Separate animals if necessary.
Sexing
Sexual differences can become more apparent with maturity.
Males may develop:
- More robust heads
- Stronger colouration
- More territorial behaviour
depending upon individual and population.
Breeding
African Red-Sided Skinks are:
oviparous — egg-laying.
Seasonal Cycling
Breeding can be influenced by seasonal changes in:
- Temperature
- Photoperiod
- Feeding
- Humidity
Courtship
Reproductive behaviour may include:
- Increased activity
- Following
- Chasing
- Courtship interactions
Nesting
Females require access to:
deep, slightly moist, secure substrate
for nesting.
Gravid Female
A gravid female may:
- Become visibly broader
- Dig repeatedly
- Become restless
- Change feeding behaviour
- Investigate nesting locations
Female Nutrition
Reproductive females require excellent:
- Calcium
- UVB
- Hydration
- Dietary quality
Clutch Size
Clutch size can vary.
A relatively small clutch of approximately:
2–6 eggs
is a reasonable expectation for a medium-sized Trachylepis, although captive reproductive data for this particular species are comparatively limited.
Breeding Data Caution
Compared with mainstream species such as Leopard Geckos or Bearded Dragons, detailed captive breeding data for T. homalocephala are limited.
Avoid treating approximate reproductive figures as absolute.
Egg Retention
Seek veterinary advice for:
- Persistent straining
- Severe lethargy
- Weakness
- Abnormal swelling
- Repeated unsuccessful nesting
Incubation
Eggs can generally be incubated under stable warm conditions around:
27–29°C
Incubation Duration
Incubation may take approximately:
50–80+ days
depending upon:
- Temperature
- Moisture
- Individual variation
Because species-specific captive data are limited, carefully document breeding results.
Incubation Medium
Use a suitable incubation medium maintained:
slightly moist rather than saturated.
Egg Handling
Avoid unnecessary rotation after laying.
Hatchlings
Hatchlings require:
- Secure accommodation
- Numerous small hides
- Appropriate basking heat
- UVB
- Fresh water
- Small live prey
Hatchling Diet
Suitable prey includes:
- Pinhead crickets
- Tiny roaches
- Small black soldier fly larvae
- Small locusts
- Other appropriately sized invertebrates
Hatchling UVB
Provide appropriate UVB from the beginning.
Growing skinks require excellent calcium metabolism.
Quarantine
New animals should undergo quarantine.
Approximately:
90 days
is a useful starting point.
Quarantine Monitoring
Record:
- Weight
- Appetite
- Faeces
- Shedding
- Hydration
- Respiration
- Activity

Common Husbandry Mistakes
Enclosure Too Small
These are active skinks.
No Climbing Opportunities
They readily use rocks, logs and raised surfaces.
No Secure Cover
An exposed enclosure can create chronic stress.
Whole Enclosure Too Hot
Provide a genuine thermal gradient.
Basking Area Too Cool
Day-active skinks require a properly heated basking surface.
Using Heat Mats as the Main Heat Source
Overhead radiant heat better recreates natural daytime conditions.
No UVB
Appropriate UVB is important for comprehensive long-term husbandry.
Using Only a Small Compact UVB Bulb
A linear T5 system provides substantially more useful coverage.
Buying the Strongest UVB Lamp Because the Species Is African
Geography alone does not determine UV requirements.
Buying UVB by Percentage Alone
The actual UVI reaching the animal is what matters.
No UV Shade
The skink must be able to escape UV exposure.
Dim Enclosure
Provide bright daytime illumination.
No Water
Fresh water should always remain available.
Feeding Only Crickets
Provide a varied diet.
Poor Gut Loading
The nutritional value of feeder insects matters.
Too Many Fatty Feeders
This can contribute to obesity.
Constant Handling
These are generally better maintained as active display reptiles.
Grabbing the Tail
Tail loss can occur.
Assuming Cohabitation Is Automatically Safe
Monitor animals carefully or house individually.

UVB in Simple Terms
If you’re choosing equipment for this species and don’t yet understand reptile UVB, concentrate on the target rather than the percentage printed on the box.
The African Red-Sided Skink is a:
DAY-ACTIVE, SUN-EXPOSING SKINK
and should have meaningful access to UVB.
Look for a:
LINEAR T5 UVB SYSTEM
rather than relying on a little compact UVB bulb.
Depending upon enclosure height and how the lamp is installed, you might use something broadly within the:
6–12% UVB range.
But that does not mean every keeper should buy a 12% tube.
What we’re actually trying to achieve is:
approximately UVI 3–4 at the main basking position.
A lower-output lamp mounted closer can sometimes produce that.
A stronger lamp mounted farther away can also produce it.
Mesh can reduce the amount reaching the skink.
So don’t think:
“12% must be better than 6%.”
Think:
“Which lamp and distance will give my animal UVI 3–4?”
The main basking area should combine:
HEAT + BRIGHT VISIBLE LIGHT + UVB
and the rest of the enclosure should progressively provide:
less UV → partial shade → complete shade.
The skink chooses where it wants to be.
Also remember that the equipment performs different jobs:
Basking lamp = HEAT
T5 UVB tube = ULTRAVIOLET
Daylight LED = BRIGHT VISIBLE LIGHT
If you don’t own a UV meter, use the current distance chart supplied by the manufacturer of the exact T5 system you buy and take any mesh into account.
You don’t need to understand all of reptile lighting science before buying your first setup.
You do need to understand that the goal isn’t the strongest lamp — it’s the correct UV exposure at the animal’s basking position, with plenty of shade available.
