Giant Day Gecko Care Instructions

Giant Day Geckos (Phelsuma grandis) are a species of diurnal (active during the day) geckos native to Madagascar and other nearby islands in the Indian Ocean. They are known for their vibrant green coloration with red markings, large size compared to other day geckos, and their active and arboreal nature. Here's a detailed care guide for keeping Giant Day Geckos healthy and happy:

Habitat Setup:

  1. Enclosure: Provide a vertically oriented terrarium to accommodate their arboreal lifestyle. A 20-gallon tall terrarium or larger is suitable for a single gecko, while larger enclosures are preferable for pairs or small groups. Ensure the enclosure has secure mesh ventilation to maintain airflow.

  2. Substrate: Use a substrate that retains moisture well, such as coconut fiber, peat moss, or orchid bark. This substrate not only helps maintain humidity levels but also provides a naturalistic environment for the geckos.

  3. Temperature and Lighting:

    • Daytime Temperature: Maintain a temperature gradient ranging from 80-85°F (26-29°C) on the cooler end to 88-90°F (31-32°C) on the warmer basking spot.
    • Nighttime Temperature: Allow temperatures to drop slightly to around 70-75°F (21-24°C).
    • UVB Lighting: Provide UVB lighting for 10-12 hours a day using a fluorescent UVB bulb appropriate for the size of the enclosure. This aids in calcium metabolism and prevents metabolic bone disease.

  4. Humidity: Giant Day Geckos require moderate to high humidity levels, typically between 60-80%. Maintain humidity by misting the enclosure with water at least twice daily, or as needed to keep the substrate and foliage moist.

Diet:

  1. Feeding: Giant Day Geckos are primarily insectivores. Offer a variety of appropriately sized live insects such as crickets, roaches, mealworms, waxworms, and fruit flies. Feed them every other day, providing as much food as they can consume in 10-15 minutes.

  2. Supplements: Dust feeder insects with calcium powder (without vitamin D3) three times a week, and with a vitamin supplement containing D3 once a week to ensure proper calcium absorption and overall health.

  3. Occasional Treats: Offer occasional treats such as mashed fruit (e.g., banana, mango, papaya) or commercially prepared gecko diet to provide variety in their diet.

Environmental Enrichment:

  1. Branches and Foliage: Furnish the enclosure with plenty of branches, vines, and live or artificial plants to create a naturalistic environment. Suitable plants include pothos, ficus, bromeliads, and orchids, which provide climbing opportunities and hiding spots.

  2. Hiding Places: Include cork bark tubes, hollow logs, or commercial reptile hides to give your gecko places to retreat and feel secure.

  3. Water Source: Provide a shallow water dish for drinking and soaking. Ensure the water is changed daily to maintain cleanliness.

Health and Maintenance:

  1. Monitoring: Regularly monitor temperature, humidity, and behavior to ensure optimal conditions and detect any signs of illness or stress.

  2. Handling: Handle Giant Day Geckos infrequently and with care to avoid causing stress or injury. If handling is necessary, support the gecko gently and avoid excessive pressure on their body.

  3. Veterinary Care: Find a reptile veterinarian experienced with geckos and schedule annual check-ups to monitor your gecko's health and address any concerns promptly.

By providing proper care and a suitable habitat, you can ensure the health and well-being of your Giant Day Geckos, allowing you to enjoy their beauty and natural behaviors for years to come.
