Description de l'espèce
Geographical Origin and Habitat: This species is native to northern and northwestern Madagascar, including surrounding islands such as Nosy Be. It primarily inhabits tropical rainforests but is highly adaptable, frequently found on palm trees, banana plants, and the outer walls of houses in rural areas.
Taxonomy and Genetics: Classified in the family Gekkonidae, genus Phelsuma, scientific name Phelsuma grandis. It was historically considered a subspecies of Phelsuma madagascariensis. Genetic isolation from mainland and island populations has established it as a stable, distinct species.
Behavior and Habits: Strictly diurnal and arboreal, which is unusual for geckos. It is highly active, bold, and territorial. Males will vigorously defend their home territory from rival males. They spend much of their day basking in direct sunlight on flat branches or leaves to regulate body temperature.
Morphology: One of the largest extant day geckos, reaching up to 28-30 cm in total length. It has a bright green to neon-lime body, decorated with brilliant red spots on the back and a red stripe running from the nostril to the eye. Skin is delicate with small, granular scales. Toe pads are highly adhesive.
Soins, reproduction et cohabitation
Terrarium Setup: Requires a vertically oriented terrarium of at least 60x45x90 cm for a single adult or a pair. Furnish with smooth bamboo poles placed vertically and horizontally, along with sturdy live plants such as Sansevieria, Bromeliads, or Pothos. Use a moisture-retaining soil substrate.
Lighting and Heating: High-intensity lighting with a strong (10%) UVB bulb is mandatory. Maintain a daytime ambient temperature of 25-28°C (77-82°F) with a localized basking spot of 32-35°C (90-95°F). Nighttime temperatures should drop to 20-22°C (68-72°F) to mimic natural cycles.
Humidity and Hydration: Maintain relative humidity of 60-80%. Mist the enclosure once or twice daily with dechlorinated water. These geckos rarely drink from standing water bowls, preferring to lick water droplets off the leaves and smooth bamboo poles during and after misting.
Feeding and Supplementation: Omnivorous. Provide a diet of live gut-loaded insects (crickets, roaches, silkworms) and high-quality commercial powdered diets designed for frugivorous geckos mixed with water. Dust insects with pure calcium at most feedings and calcium with D3 twice weekly.
Compatibility: Highly territorial. Never house multiple males together. Even housing a male and a female together requires close observation, as aggressive behavior can result in severe skin tearing. Single-specimen housing is often the safest choice for beginners.
Health and Common Diseases: The skin of this species is fragile and tears easily as a defense mechanism; they should never be grabbed. Metabolic Bone Disease (MBD) is common if UVB lighting or calcium supplements are inadequate. Shedding issues can occur if humidity is too low.

Profil de reptile
- Régime alimentaire
- Omnivore
- Phelsuma grandis is primarily insectivorous, requiring a varied diet of live insects. Feeder insects should be appropriately sized, typically no larger than the space between the reptile's eyes. It is essential to dust the food items with calcium and vitamin supplements regularly. Providing gut-loaded insects ensures maximum nutritional value for the animal.
- Espérance de vie
- 15-20 years
- Taille adulte
- 28 cm
- Mode de vie/microhabitat
- Arboreal
- In the wild, Phelsuma grandis thrives in specific microclimates that provide the necessary warmth, humidity, and cover. Terrestrial species require ample floor space, while arboreal ones need vertical climbing opportunities. Maintaining an enclosure that closely mimics these natural conditions is vital for their well-being. A proper lifestyle setup reduces stress and allows the reptile to exhibit natural foraging and resting behaviors.
- Cycle d'activité
- Diurnal
- The activity pattern of Phelsuma grandis is largely dictated by its natural habitat and evolutionary adaptations. As a crepuscular or nocturnal species, it is most active during dawn, dusk, or nighttime hours. During the day, it prefers to rest in secure, dark retreats to avoid predators and extreme temperatures. Adjusting lighting and feeding schedules to match this pattern promotes a healthy and active lifestyle.
- Sociabilité
- Solitary
- Phelsuma grandis exhibits unique behaviors that are fascinating to observe in captivity. They may use body language, such as tail waving or vocalizations, to communicate with their environment or other individuals. Providing adequate hiding spots helps them feel secure and encourages natural behaviors. Careful observation can reveal a lot about their health and stress levels.
- Reproduction
- Oviparous
- Reproduction in Phelsuma grandis typically occurs after a cooling period or changes in environmental cues. Females will lay clutches of eggs, which need to be carefully incubated at specific temperatures and humidity levels. The sex of the offspring can sometimes be determined by the incubation temperature. Proper calcium supplementation is critical for breeding females to ensure healthy egg development.
- Tolérance aux manipulations
- Display only
- Handling Phelsuma grandis should be done with care and patience to avoid causing undue stress or injury. It is best to allow the reptile to walk onto your hands rather than grabbing it directly. Short, positive handling sessions can help acclimate the animal to human interaction over time. Always wash your hands before and after handling to prevent the spread of bacteria and ensure both human and reptile safety.
- Brumation
- Brumation is a natural cycle for Phelsuma grandis, often triggered by seasonal drops in temperature and daylight hours. During this time, the reptile will significantly decrease its activity and appetite, resting for weeks or months. It is crucial to monitor their weight and ensure they have access to fresh water throughout this period. Only healthy adults should be allowed to brumate, as it can be taxing on young or sick individuals.
- Mue
- Periodic
- Regular shedding, or molting, is a sign of growth and good health in Phelsuma grandis. To facilitate a smooth shed, it is important to provide a humid hide or lightly mist the enclosure when signs of shedding appear. Retained shed, especially around the toes or tail, can cause serious circulation issues and should be gently removed. Ensuring adequate humidity and rough surfaces in the enclosure helps the reptile remove old skin effectively.
