Standing's Day Gecko

Standing's Day Gecko is a striking, large-bodied gecko native to the dry spiny forests of southwestern Madagascar. Reaching 20 to 25 cm in total length, it shifts in color from grayish brown to blue-green depending on the light, giving it a dramatic, ever-changing appearance. With its bold build and confident presence, it stands out among day geckos for its sheer physical presence. Because wild populations have suffered from overcollection, attentive care in captivity matters all the more. This is considered a species for experienced keepers, requiring a spacious enclosure and careful attention to temperature and humidity — but for those ready to meet its needs, it makes for a rewarding, long-term companion.

Standing's Day Gecko key facts

Care level
Advanced
Lifespan
15-20 years
Size
20-25cm total length, sometimes larger
Temperature
Humidity
40〜75%
Diet
Crickets and dubia roaches, prepared fruit-based gecko diet, nectar
Temperature & Humidity
Keep the basking spot at 32-35C, the cool zone at 24-31C and night-time temperatures at 22-23C. Aim for average humidity of 40-75 per cent. Although it is a dry-forest species, letting humidity fall too low causes shedding problems, so mist morning and evening. Target a UV index of 3.0-4.0 at the basking site.
Enclosure
As a large, active arboreal species it needs a tall enclosure of at least 60 x 60 x 120 cm even for one animal. Run thick branches and driftwood at several levels and provide a well-lit basking branch near the top. Live plants and a moisture-retentive substrate hold humidity; suspend heat lamps clear of the mesh top to prevent burns.
Diet & Feeding
In the wild it takes insects and other invertebrates and will even eat smaller lizards, supplementing this with soft fruit, pollen and nectar. In captivity use a prepared fruit-based gecko diet as the base with crickets and dubia roaches alongside, dusting the feeders with calcium.
Temperament
In the wild it lives in pairs in trees. Breeding pairs have been kept together successfully, but males must never be housed together. Unless breeding, a single animal or a group of females is safer, and any animals that fight should be separated at once. It is fast and thin-skinned, so it is not suited to handling.
Notes
It belongs to Phelsuma, listed on CITES Appendix II, so import requires an export permit from the exporting country; Appendix II animals need no Japanese registration certificate. The IUCN assesses it as Vulnerable, with illegal collection for the pet trade named as a threat, so choose captive-bred animals and confirm the origin of any animal you acquire.

About Standing's Day Gecko

A guide to Standing's Day Gecko, a large day gecko species endemic to Madagascar, covering its traits, temperament, and what experienced keepers should know before bringing one home.

7 things to know before welcoming a Standing's Day Gecko

  1. 1Needs a Spacious Enclosure

    Reaching 20-25 cm in length, this gecko needs a tall, roomy enclosure with plenty of depth. Fill it with plants and branches to create vertical space where it can move around actively.

  2. 2Light and UVB Matter

    Its coloration shifts from grayish brown to blue-green depending on light intensity. Proper UVB exposure and a consistent lighting cycle are essential for its health.

  3. 3Prefers a Drier Setup

    This species comes from dry spiny forest habitat. Avoid excessive humidity and aim for a clear dry-humid cycle in your husbandry.

  4. 4Skittish and Alert

    Standing's Day Geckos are wary and quick-moving, making them poorly suited to handling. They're best enjoyed as an animal to observe rather than hold.

  5. 5Delicate Skin

    Like other day geckos, its skin is thin and delicate and can tear if gripped too firmly. Keep handling to an absolute minimum.

  6. 6A Long-Term Commitment

    With a lifespan of 15 to 20 years, this is a long-term companion that calls for lasting commitment.

  7. 7Best for Experienced Keepers

    This species is generally considered suitable for experienced keepers. Prior experience with day geckos or other arid-adapted reptiles is a real advantage.
