Ornate Day Gecko (Phelsuma ornata) Care Sheet
The Ornate Day Gecko (Phelsuma ornata) is a small, brilliantly coloured diurnal gecko native to Mauritius and several surrounding islands in the Indian Ocean.
Despite its relatively small size, it is an exceptionally striking species. Adults typically combine bright green, turquoise or blue-green colouration with red, orange and dark markings across the head and back. The vivid patterning responsible for its common name makes it an outstanding naturalistic display animal.
Ornate Day Geckos are strongly arboreal and spend much of their lives climbing trees, shrubs, palms and other vegetation. They are active during daylight and require bright visible lighting, appropriate UVB and access to a localised basking area.
Like other members of the genus Phelsuma, they possess delicate skin and specialised adhesive toe pads. They can move extremely quickly across both rough and smooth surfaces and should not be regarded as reptiles intended for routine handling.
Successful husbandry centres on a secure vertical enclosure, abundant climbing structure, strong appropriate lighting, UVB, a thermal gradient, fluctuating humidity, excellent ventilation and a varied omnivorous diet.

Natural Distribution
The Ornate Day Gecko is native to Mauritius and associated offshore islands.
Island reptiles can be particularly vulnerable to environmental change because their natural distributions are often comparatively restricted.
Threats to island reptile populations may include:
- Habitat loss
- Habitat modification
- Introduced predators
- Invasive species
- Collection pressure
Responsible captive breeding provides a sustainable source of animals for herpetoculture.
Natural Habitat
Ornate Day Geckos inhabit warm, vegetated environments.
They may utilise:
- Trees
- Shrubs
- Palms
- Coastal vegetation
- Broad-leaved plants
- Forest edges
- Vegetation around buildings
They spend most of their lives above ground.
Captive accommodation should therefore emphasise usable vertical space and abundant climbing opportunities.
Appearance
Ornate Day Geckos are highly variable and colourful.
Typical colours can include:
- Bright green
- Turquoise
- Blue
- Red
- Orange
- Yellow
- Black
Many individuals display contrasting markings across the:
- Head
- Neck
- Back
- Tail
Their colouration can appear particularly intense under high-quality full-spectrum visible lighting.
Colour Variation
Colour intensity varies according to:
- Individual genetics
- Age
- Sex
- Temperature
- Lighting
- Activity
- Stress
- Health
Temporary changes in colour are normal.
Adult Size
Adults generally reach approximately:
4–5 inches total length
including the tail.
Although small, they are highly active and benefit from considerably more space than their body length alone might suggest.
Behaviour
Ornate Day Geckos are strongly active during daylight.
Normal behaviour includes:
- Basking
- Climbing
- Hunting insects
- Exploring vegetation
- Territorial displays
- Licking nectar-like foods
- Drinking droplets
- Moving between exposed and shaded areas
They are highly visual and rapidly respond to movement.
Temperament
Ornate Day Geckos are generally nervous rather than aggressive towards people.
They are:
- Extremely quick
- Agile
- Excellent climbers
- Capable of sudden jumps
They are best maintained primarily as display animals.
Handling
Routine handling is not recommended.
When an animal must be moved, guiding it carefully into a secure container is generally safer than catching it by hand.
Never:
- Grab the tail
- Squeeze the body
- Restrain the skin
- Chase the animal excessively
- Handle it in an unsecured room
Delicate Skin
Like other Phelsuma, Ornate Day Geckos possess delicate skin.
Rough restraint can cause sections of skin to tear away.
This defensive adaptation is an important reason to minimise unnecessary handling.
Tail Loss
Ornate Day Geckos can shed their tails when severely stressed or improperly restrained.
Never lift or restrain a gecko by its tail.
A regenerated tail may differ noticeably from the original.
Enclosure Size
For a single adult:
18" × 18" × 24"
should be considered a practical minimum.
Larger accommodation is preferred where possible.
Additional space allows:
- Greater exercise
- More climbing opportunities
- Better thermal gradients
- Better UV gradients
- Denser planting
- Greater behavioural choice
Vertical Space
Vertical space is essential.
The enclosure should contain climbing structures throughout its height.
A tall but empty enclosure provides little useful habitat.
Climbing Structure
Suitable furnishings include:
- Bamboo
- Natural branches
- Cork
- Vines
- Live plants
- Artificial foliage
Arrange climbing surfaces:
- Vertically
- Horizontally
- Diagonally
This allows the gecko to travel throughout the enclosure.
Bamboo
Bamboo is particularly useful for day geckos.
It provides:
- Smooth climbing surfaces
- Basking locations
- Resting areas
- Visual barriers
Use several different diameters where possible.
Ensure all pieces are securely positioned.
Foliage
Dense foliage provides:
- Security
- Shade
- Drinking surfaces
- Climbing opportunities
- Humidity gradients
- Visual barriers
Suitable reptile-safe plants may include:
- Pothos
- Ficus
- Schefflera
- Bromeliads
- Other suitable tropical plants
All plants should be free from pesticides and harmful chemicals.
Hides
Provide elevated cover using:
- Dense vegetation
- Cork
- Hollow bamboo
- Concealed areas behind plants
The gecko should always have the opportunity to move completely out of sight.
Enclosure Security
Escape prevention is critical.
Ornate Day Geckos can exploit extremely small gaps.
Carefully check:
- Doors
- Sliding tracks
- Ventilation
- Cable ports
- Lid fittings
before introducing the animal.
Ventilation Mesh
Ventilation mesh must be fine enough to prevent escape while maintaining good airflow.
Remember that very small feeder insects may also escape through coarse mesh.
Substrate
Suitable substrates include:
- Organic topsoil
- Coco fibre
- Tropical soil mixtures
- Orchid bark
- Leaf litter
The substrate should retain some moisture while allowing adequate drainage.
Bioactive Housing
Ornate Day Geckos are well suited to naturalistic bioactive enclosures.
A properly established system may contain:
- Live plants
- Natural soil
- Leaf litter
- Springtails
- Suitable small isopods
Bioactive housing does not remove the need for routine observation and maintenance.
Temperature Gradient
Provide a clear thermal gradient.
The entire enclosure should never be maintained at basking temperature.
Basking Temperature
Provide a localised basking area around:
29–32°C
The gecko must be able to move away easily.
General Day Temperature
Most of the enclosure can remain around:
23–27°C
Cool Area
Provide cooler shaded regions around:
21–24°C
Night Temperature
Night temperatures can generally fall to approximately:
18–22°C
A modest nighttime reduction is appropriate.
Overheating
Avoid allowing the entire enclosure to become excessively warm.
Small arboreal enclosures can overheat rapidly, particularly during summer.
Always provide cooler shaded retreats.
Heating
Where supplemental heating is required, use appropriate overhead heating to create a localised basking zone.
Heating equipment should be safely controlled and monitored.
UVB
UVB is essential.
Ornate Day Geckos are strongly diurnal reptiles naturally exposed to daylight.
Appropriate UVB supports:
- Vitamin D3 synthesis
- Calcium metabolism
- Healthy skeletal development
- Natural basking behaviour
UV Gradient
Provide access to:
- Appropriate UV exposure around basking areas
- Moderate exposure
- Filtered exposure
- Complete shade
The gecko must be able to regulate its exposure behaviourally.
UVB Placement
UVB effectiveness depends on:
- Lamp output
- Distance
- Mesh obstruction
- Reflector
- Enclosure design
Follow current manufacturer guidance when selecting and positioning UVB equipment.
Visible Lighting
Bright visible lighting is extremely important.
These are active daytime reptiles.
High-quality lighting encourages:
- Natural activity
- Feeding
- Basking
- Colour display
- Plant growth
Suitable daylight LED lighting can be used alongside UVB and basking equipment.
Photoperiod
Approximately:
11–13 hours of daylight
is suitable depending on season.
Night Lighting
The enclosure should become dark at night.
Do not leave visible red, blue or purple lamps operating throughout the night.
Humidity
General humidity around:
60–80%
is appropriate.
Humidity should fluctuate naturally rather than remaining constantly high.
Humidity Cycle
Humidity will normally increase after misting before gradually falling as ventilation dries the enclosure.
This fluctuation is desirable.
The enclosure should not remain permanently saturated.
Misting
Light misting:
Once or twice daily
works well in many setups.
Frequency depends on:
- Ventilation
- Planting
- Substrate
- Room humidity
- Season
Allow enclosure surfaces to partially dry between misting sessions.
Hydration
Ornate Day Geckos frequently drink droplets from:
- Leaves
- Glass
- Bamboo
- Branches
Regular misting therefore provides important drinking opportunities.
Water Bowl
A small shallow water dish can also be provided.
Keep it clean and replace the water regularly.
Ventilation
Excellent ventilation is essential.
High humidity combined with stagnant air can encourage:
- Mould
- Bacterial growth
- Skin problems
- Respiratory disease
The enclosure should remain humid but fresh.
Diet
Ornate Day Geckos are omnivorous.
Their captive diet should include:
- Appropriately sized live insects
- Suitable nutritionally complete gecko diet
Dietary variety is important.
Live Insects
Suitable feeders include:
- Small crickets
- Small locusts
- Small roach nymphs
- Fruit flies
- Small black soldier fly larvae
- Other appropriately sized captive-produced insects
Prey should be appropriately sized.
Gut Loading
Feeder insects should be properly gut-loaded before use.
Suitable foods include:
- Leafy greens
- Vegetables
- Appropriate commercial gut-loading diets
Calcium Supplementation
Live insects should be appropriately dusted with calcium.
Requirements depend on:
- Age
- UVB provision
- Diet
- Reproductive status
Breeding females require particularly careful calcium management.
Multivitamins
A suitable reptile multivitamin can be offered periodically.
Avoid excessive supplementation.
Complete Gecko Diet
A nutritionally complete commercial gecko diet can provide the fruit and nectar-like component of the captive diet.
Prepare according to manufacturer instructions.
Offer small fresh portions and remove uneaten food before it spoils.
Fresh Fruit
Small quantities of suitable soft fruit may occasionally be offered as enrichment.
Fresh fruit should not replace a nutritionally complete diet.
Feeding Frequency
Juveniles can generally be offered food:
Daily or almost daily
Adults can generally be fed:
4–5 times per week
using a varied combination of live insects and complete gecko diet.
Adjust feeding according to:
- Body condition
- Activity
- Reproductive status
Feeding Ledges
Elevated feeding stations are useful.
These allow the gecko to feed naturally without descending to the enclosure floor.
Food Enrichment
Encourage natural feeding behaviour by:
- Offering live insects
- Varying feeding locations
- Using elevated feeding stations
- Allowing controlled hunting among foliage
Social Housing
Individual housing is the safest general recommendation.
Ornate Day Geckos can be territorial.
Adult Males
Adult males should not normally be housed together.
Territorial aggression may result in:
- Bite injuries
- Chronic stress
- Feeding suppression
- Restricted access to basking areas
Male/Female Housing
Experienced breeders may maintain compatible male/female pairs in sufficiently large and densely furnished enclosures.
Females must be monitored carefully for:
- Persistent courtship
- Mating injuries
- Stress
- Feeding competition
Separate accommodation should always be available.
Female Aggression
Females may also display territorial behaviour.
Do not assume females will automatically coexist peacefully.
Sexing
Mature males generally develop:
- More pronounced preanal/femoral pores
- Broader tail base
- More obvious reproductive structures
Sexing juveniles can be considerably more difficult.
Breeding
Ornate Day Geckos can be bred successfully in captivity.
Only healthy mature animals in excellent condition should be bred.
Female Condition
Breeding females require excellent:
- Nutrition
- Calcium provision
- UVB
- Hydration
- Body condition
Repeated egg production can place considerable demands on females.
Egg Laying
Females generally produce:
2 eggs per clutch
although single eggs can occasionally occur.
Multiple clutches may be produced during a breeding season.
Egg Deposition
Eggs may be deposited in protected locations such as:
- Bamboo
- Cork
- Plant structures
- Concealed enclosure furnishings
The species produces adhesive eggs which may become firmly attached to the laying surface.
Do not forcibly remove firmly attached eggs.
Egg Protection
Where eggs remain inside the adult enclosure, a ventilated protective cover may sometimes be positioned around them.
This can help:
- Protect the eggs
- Prevent adults disturbing hatchlings
- Contain newly emerged young
Incubation
Eggs can generally be incubated around:
24–27°C
under stable conditions.
Incubation commonly lasts approximately:
45–70+ days
depending on temperature and other factors.
Avoid excessive incubation temperatures.
Hatchlings
Hatchlings are extremely small and fast.
Provide:
- Secure escape-proof accommodation
- Fine climbing structures
- Dense foliage
- Appropriate UVB
- Moderate basking temperatures
- Regular misting
- Tiny live prey
- Suitable complete gecko diet
- Appropriate supplementation
Hatchling Food
Suitable prey may include:
- Flightless fruit flies
- Pinhead crickets
- Tiny roach nymphs
- Other appropriately sized feeders
Hatchling Security
Escape prevention is critical.
Young day geckos can pass through tiny gaps around:
- Doors
- Ventilation
- Cable ports
- Sliding tracks
Check accommodation carefully before introducing hatchlings.
Quarantine
All newly acquired reptiles should undergo quarantine.
A minimum of approximately:
90 days
is a sensible starting point.
Monitor:
- Feeding
- Weight
- Faeces
- Skin
- Shedding
- Respiration
- Activity
Shedding
Healthy Ornate Day Geckos generally shed successfully when correctly hydrated.
Retained shed may occasionally occur around:
- Toes
- Tail
- Limbs
Avoid forcibly pulling firmly attached skin.
Toe Health
Healthy adhesive toe pads are essential for normal climbing.
Retained shed or contamination can interfere with grip.
Inspect feet periodically.
Signs of Good Health
A healthy Ornate Day Gecko should generally display:
- Clear bright eyes
- Strong grip
- Alert daytime activity
- Regular basking
- Active hunting
- Appropriate body condition
- Smooth coordinated climbing
- Healthy skin
- Normal faeces
Warning Signs
Seek veterinary advice for:
- Persistent food refusal
