Giant Day Gecko Enclosure Size

1. Giant day geckos require a spacious enclosure to allow them to engage in natural behaviors and have ample space for climbing.

2. The minimum recommended enclosure size for a single giant day gecko is 24”L x 24”W x 48”H / 60 x 60 x 120 cm or similar.

3. Giant day geckos can grow up to 11″/28cm long, so the enclosure should be large enough to accommodate their size.

4. It is important for the enclosure to provide opportunities for the gecko to explore, hunt, and exercise.

5. Whenever possible, it is better to provide a larger enclosure for giant day geckos.

Can multiple giant day geckos be housed in the same enclosure?

1. Historically, day geckos have been successfully housed in breeding pairs or small groups with one male and multiple females. 2. If breeding is not intended, it is recommended to keep only one day gecko or a group of strictly females.
3. When housing multiple day geckos together, the enclosure size should be increased in proportion to allow the geckos to have space and get away from each other as necessary.

Lighting & UVB for Giant Day Geckos

1. Giant day geckos are diurnal and need access to a basking area and direct UVB during the day.

2. Lights should be on for 13 hours/day in summer and 11 hours/day in winter.

3. UVB lighting is crucial for giant day geckos to survive and display their best colour.

4. The strength of UVB depends on distance, and appropriate lamps should be used based on the enclosure's height.

5. Reptile-specific fixtures should be used for best results, and UVB bulbs should be replaced every 12 months.

6. Bright lighting with a colour temperature of around 6500K should be provided in addition to UVB and heat lamps.

7. Bright lighting can make giant day geckos more active, improve their appetite, and enhance their colour.

8. The  LED Bar and Glow & Grow are recommended lamps for general illumination.

Giant Day Gecko Temperature Requirements

- Humans are warm-blooded, while giant day geckos are cold-blooded and need to regulate their body temperature by moving between areas of different temperatures.

- In the wild, giant geckos warm up by basking in sunlight, which can be replicated in captivity with a white incandescent heat lamp.

- The recommended temperatures for the basking area, cool zone, and night time for giant geckos are provided.

- To ensure proper thermoregulation, the basking area should be positioned directly under the heat lamp, and vines, branches, and foliage should be provided at all levels in the enclosure.

  • Basking area temperature: 85-90°F (29-32°C)
  • Cool zone temperature: 77-82°F (25-28°C)
  • Nighttime temperature: 73-77°F (23-25°C)

Giant Day Gecko Humidity Requirements

1. Giant day geckos require a moderate to high humidity environment between 40-75%.

2. Consistently high or low humidity levels can lead to health issues for geckos.

3. Humidity levels naturally vary between warm and cool areas, as well as between day and night.

4. To increase humidity, use a pump-style pressure sprayer to mist the enclosure twice a day.

Giant Day Gecko Substrate Options

1. Giant day geckos benefit from using bedding to stabilize humidity and provide cushioning when they fall.

2. Moisture-retentive substrates similar to their natural habitat soil are ideal for giant day geckos.

3. There are several reliable options for bedding, including DIY tropical mix, products, soil, and Terra Fauna bioactive kit.

4. Regular cleaning is necessary, with feces and urates removed daily and contaminated substrate replaced every 3-4 months.

Decorating Your Giant Day Gecko Terrarium

1. Decorations are important for a gecko's enclosure as they provide environmental enrichment, stimulate natural instincts, and promote overall wellbeing.

2. Without decorations, the terrarium is just a plain box with dirt and a feeding ledge.

3. Geckos need climbing materials and places to hide that are not on the ground, even though they can climb glass.

4. Some suggestions for gecko decorations include branches, cork hollows, vines, live plants, and magnetic ledges.

5. It is best to avoid artificial plants with day geckos and arrange the decorations in a way that encourages climbing, exploration, and provides areas of both light and shade.

Feeding Your Giant Day Gecko

Giant day geckos, being omnivorous creatures, require a well-rounded diet consisting of both plants and animals in order to obtain the necessary nutrients for their well-being. They primarily consume insects, flower nectar, and fruit juice while in their natural habitat. When used as companions, this food regimen can be replicated by combining a suitable amount of meal replacement powder with live insects.

The frequency at which giant day geckos should be fed is determined by their age.

For young insects (0-6 months old), they should be fed with live insects on a daily basis and offered commercially available insect diets every other day.
Insects should be provided to subadults and adult insects more than 6 months old two to three times per week. Additionally, they should be given complete gecko diet once a week.
It is necessary to provide the crested gecko diet (CGD) using a feeding ledge attached to the wall, instead of placing it on the floor. In my personal opinion, I find magnetic mounts more favourable than suction cups.

The ideal insects to feed giant day geckos include crickets, dubia roaches, discoid roaches, red runner roaches, red head roaches, grasshoppers/locusts, hornworms, and silkworms.

Variety is the crucial factor in ensuring that your pet receives a nutritious and well-balanced diet. If you offer a diverse range of food to your pet, you will have the benefit of a healthier pet that is always excited about mealtime. I like to have a selection of at least 3 different types/flavours of CGD on hand and switch between them.


The diet of crested geckos is already enriched and well-balanced with diverse range of vitamins and minerals. Nevertheless, it is necessary to apply thin layer of calcium powder onto feeder insects prior to each feeding in order to maintain proper balance between calcium and phosphorus.

While there are numerous choices available, both CalciumPro Mg and Miner-All Outdoor are reliable calcium supplements. In order to achieve optimal outcomes, follow the instructions provided on the label.

Drinking Water

Even though your gecko will hydrate itself through daily mistings, it is advisable to have bowl of fresh water available on the feeding ledge at all times. For proper hygiene, it is recommended to clean this bowl thoroughly once week using veterinary disinfectants like Rescue or F10SC.

Handling Your Giant Day Gecko

Although giant day geckos can be safely handled due to their size, it is crucial to bear in mind that they possess highly sensitive skin, much like other day geckos. If you are interested in engaging with your gecko, suggest restricting your interactions to either hand-feeding them insects using feeding tongs with soft tips or placing small amount of CGD on your finger for them to taste. If your gecko becomes sufficiently trusting of you, it might climb onto your hand or arm. But never snatch it!

Ensure to give the gecko minimum of weeks to adapt to its new environment before attempting to initiate any interaction
