Giant Day Gecko Care Sheet

Lizards Home > Library
The Giant Day Gecko (Phelsuma madagascariensis grandis) is a green colored lizard, often with red or orange spotted patterns running down their heads and back. This species is diurnal, meaning they are active during the day.

The Giant Day Gecko is a large species of omnivorous gecko, as can probably be determined by its name. They are originally from the island of Madagascar off the coast of Africa, and can live up to about 11 years.

Food & Water

The Giant Day Gecko is omnivorous, eating both insects and fruits. They can be fed crickets, mealworms, waxworms, butterworms etc. two to three times a week, along with different types of fruit occasionally. For the meat side of their diet, crickets should form the staple, while fatty insects like waxworms and butterworms should only be fed occasionally. In the wild, a staple food is flower nectar. All insects should be gut-loaded before feeding to your Gecko. You should also dust the insects with a multi-vitamin supplement. You can get reptile Vitamin Spray as well, from your local pet store. Leave a dish with water in the habitat at all times. Ensure that the water is clean, changing it everyday. You can also mist them, but they will get most of their water from the dish.

Lighting, Temperature & Humidity

Use broad spectrum heat bulbs, and a fluorescent or other bulb with UVB. Direct sunlight (not through glass) is recommended for natural vitamins. Keep the humidity around 65%. You can use misting to raise the humidity levels if needed. The temperature should be kept between 80 degrees F to 85 degrees F. Do not let the temperature get above 90 degrees F. The temperature should never fall below 70 degrees F.


Giant Day Geckos need a fairly large enclosure. A 2.5' x 2.5' x 2.5' as a minimum size should be sufficient for one, but bigger is always better. Never house 2 males together, as they will become territorial, aggressive and fight each other. Make sure to include cover for the Gecko to hide under. Also include some branches for climbing, as the Giant Day Gecko is very active. Use large bark chips, reptile carpet or newspaper for a substrate.
