Background Information

The giant day gecko (*Phelsuma grandis*) is a vibrant and striking lizard native to the lush forests of Madagascar and the nearby Comoros Islands. Known for their bright green color and distinctive red spots, these geckos are diurnal, meaning they are active during the day. They are popular among reptile enthusiasts due to their beautiful appearance and relatively docile nature.

 

 Lifespan

In captivity, giant day geckos can live for 15-20 years with proper care.

 

 1. Housing

 Enclosure Size

- **Juveniles:** A 10-gallon tall terrarium is suitable.

- **Adults:** A minimum of 40-gallon tall terrarium (at least 30 inches tall) is recommended, as they thrive in vertical spaces.

 

 Enclosure Type

- Glass terrariums or pvc enclosures with good ventilation. A secure lid is crucial to prevent escapes.

 

 Substrate

- **Options:** Coconut fiber, cypress mulch, or a bioactive substrate mix.

 

 Hiding Spots and Climbing Opportunities

- Provide multiple hiding spots using logs, plants, or commercial hides.

- Include branches, vines, and live or artificial plants to create climbing structures, as they are arboreal and enjoy vertical space.

 

 Temperature and Humidity

- **Temperature:** Maintain a daytime temperature of 75-85°F (24-29°C), with a basking spot reaching 85-90°F (29-32°C). Nighttime temperatures can drop to 70-75°F (21-24°C).

- **Humidity:** Aim for 60-80%. Use a hygrometer to monitor levels and mist the enclosure daily to maintain humidity.

​

2. Feeding

 Diet

Giant day geckos are primarily insectivorous but can also benefit from fruits and commercial diets. A balanced diet includes:

- **Insects:** Crickets, mealworms, roaches, and other insects. Offer every other day.

- **Fruits:** Mashed bananas, papaya, or commercial fruit mixes. Provide in moderation.

- **Commercial Diets:** Specially formulated diets for day geckos can be used as a staple.

 

 Feeding Schedule

- **Juveniles:** Feed insects daily and fruits every few days.

- **Adults:** Feed insects every other day and fruits 1-2 times a week.

 

 Hydration

- Provide fresh water in a shallow dish and mist the enclosure regularly to ensure hydration.

 

 3. Handling

 Acclimation

- Allow your giant day gecko to acclimate for a week before handling.

 

 Handling Tips

- Approach slowly and gently. Support their body with both hands.

- Limit handling sessions to avoid stress, especially for new geckos.

 

 Signs of Stress

- Signs include hiding, rapid breathing, or tail dropping. If stressed, return them to their enclosure.

​

4. Health Care

 Regular Health Checks

- Monitor for signs of lethargy, weight loss, or shedding issues.

 

 Shedding

- Giant day geckos typically shed every few weeks. Ensure humidity is adequate to assist in the shedding process.

 

 Veterinary Care

- Establish a relationship with a veterinarian who is experienced in reptiles. Schedule regular check-ups and seek immediate care for any health concerns.

​

5. Behavior and Enrichment

 Social Behavior

- Generally friendly but can be territorial, especially males. It’s best to keep a single male with females or in separate enclosures.

 

 Enrichment

- Provide climbing opportunities, hiding spots, and foliage to stimulate natural behaviors.

- Rotate decorations to keep the environment interesting.

 

 6. Common Issues

 Metabolic Bone Disease (MBD)

- Caused by insufficient calcium or UVB exposure. Symptoms include lethargy and deformities. Ensure a balanced diet and appropriate lighting.

 

 Parasites

- Signs include weight loss, abnormal feces, or lethargy. Consult a vet for diagnosis and treatment if necessary.

 

 Dehydration

- Ensure access to fresh water and adequate humidity. Signs of dehydration include wrinkled skin and lethargy.
