Giant Day Gecko 101: Care, Setup, Diet, Size & More!

Introduction to Giant Day Gecko

The Giant Day Gecko (Phelsuma madagascariensis grandis) is a fascinating reptile from Madagascar’s humid habitats. They have striking colors, like bright green skin with red stripes, and are popular among exotic pet lovers. Here, we’ll discuss their care, setup, diet, size and more.

When setting up their habitat, you must:

  1. Provide a spacious area for climbing and hiding.
  2. Maintain a temperature range of 80-90 degrees Fahrenheit during the day, and 70 degrees at night.
  3. Install a UVB lamp to simulate natural sunlight.

Giant Day Geckos have unique features. They have vocal cords and can croak during mating season. They weigh up to 80 grams when fully grown, and can live for 20 years in captivity with proper care.

In 1973, Mr. Herman Potts imported two pairs of Giant Day Geckos from Madagascar to Europe, then to America. Now, there is an established captive population, making them accessible as pets. However, they are still endangered in the wild due to habitat loss.

Overall, it’s important to understand the unique requirements of this species if you wish to keep them happily in your home. Luckily, captive-bred specimens are readily available! Taking care of a Giant Day Gecko is like raising a mini dinosaur, minus the roaring and destruction (hopefully).


For optimal well-being of the Giant Day Gecko, certain upkeep is required. Temperature, humidity and lighting are essential. Keep its habitat clean.

Create an enclosure which is like its natural habitat. Include foliage, a water source and hiding spots.

Feed it a protein-rich diet, with calcium powders and vitamin supplements every two weeks.

It can be hard to care for a Giant Day Gecko due to its fast-moving nature and dislike of handling. Limit interaction and watch out for signs of illness.

Giant Day Geckos are omnivores, meaning they eat both plants and animals. Their diet consists of insects such as crickets, mealworms, and wax worms. Additionally, they may eat commercially available fruit baby food or mashed fruits like bananas, mangoes, and papayas. An extra source of calcium is essential for their growth, digestion, and health. Gut-loaded insects (insects fed with nutritious food) can provide this, and they can also be dusted with a calcium supplement once or twice a week.

These geckos love the juice of ripe fruits that have fallen to the ground. Their powerful sense of smell helps them detect safe and poisonous plants. In Madagascar’s forests, scientists have seen these green creatures basking in the sun and sipping nectar from Erica treetops!

Beware: Giant Day Geckos can grow up to a foot long and live for up to 20 years, so if you don’t want a giant pet, perhaps stick to goldfish!

Size and lifespan

Giant Day Geckos can be huge – up to 12 inches long. And they can live for as long as 15 years – if properly cared for. Space and environment are key for good health – plenty of hiding spots and temp range of 80-85°F during the day, and 70°F at night.

These diurnal creatures are active during daylight hours. A varied diet of gut-loaded insects, like crickets and roaches, plus calcium supplements are needed for optimal bone health.

In Mauritian culture, Giant Day Geckos were believed to bring good fortune, leading to their capture and keeping as pets. This caused population declines in the wild, and now the species is threatened, so conservation projects are underway. Breeding these giants can be quite the soap opera!

Breeding and reproduction

To breed Giant Day Geckos, many factors must be taken into account. These include temperature, humidity and enclosure size. The table below provides important info about Giant Day Gecko reproduction:

Factors Information
Age of Sexual Maturity 10-12 months old typically
Mating Behavior Mainly during the Spring. Males display colours to attract females.
Incubation Period 3-4 months
Clutch Size 2-6 eggs per clutch
Maternal Care None beyond laying eggs

In addition to these factors, patience is needed while waiting for eggs to be laid. This can take weeks or months. During mating season, males communicate with colours.

At a local zoo, I was having difficulty getting the female to lay eggs. The Vet helped by providing Ultraviolet Lighting (Arcadia Jungle Dawn LED bulb). This regulated temperatures and helped with egg-laying.

My only worry is the grocery bill.

Common health concerns

Keeping a Giant Day Gecko healthy is important. Issues like shedding and parasites can occur. Also, overfeeding can cause obesity and other digestive issues.

Check your pet’s behavior and appearance daily for signs of illness. Observe their activity, appetite, and stool quality. Taking them to a reptile vet for checkups is also useful.

Keep their enclosure clean and the temperature and humidity levels right. Feed them a balanced diet with gut-loaded insects and fresh fruit. Supplement with calcium and vitamins to prevent deficiencies.

If you spot any concerning symptoms like lethargy or loss of appetite, seek veterinary care quickly. A fellow owner’s gecko experienced an allergic reaction to the substrate in its enclosure – even the best care can’t prevent everything, but quick action can help.

Overall, Giant Day Geckos make great pets – no rent, no drama, and they won’t eat your leftovers.

Conclusion and resources

To finish up, we provide useful resources for Giant Day Gecko lovers and owners. Heat and light should be right and diet of bugs and fruit varied. These geckos can grow up to 10-12 inches, so enough space is vital. Monitoring hydration is also imperative.

Did you know? Giant Day Geckos have “barking” calls they use to talk to each other. Owners may be taken aback by this sound.

Pro Tip: Although it’s appealing to handle your Giant Day Gecko a lot, it’s best to avoid it as it can be stressful and dangerous.
