Day Gecko


Female Madagascan Giant Day Gecko CB Sub Adult

Giant Day Geckos are large green geckos from Madagascar. They are found in the rainforest and are extremely active during the day.
Day geckos are cold blooded and are known as ‘exothermic’– meaning that they need heat from an outside source in order to maintain their body temperature.

Day geckos enjoy an arboreal enclosure to provide them with plenty of space to exercise as they would in the wild. They enjoy climbing and jumping. Day geckos can be kept in a bio-active terrarium which replicates their environment in the wild.

Day Geckos are fast moving, timid lizards who make excellent display pets. Care should be taken if handling to clean the enclosure as these geckos will run away very quickly. We recommend catching your lizard inside a plastic tub.


Day Geckos enjoy an arboreal environment with plenty of space to jump around. Other geckos such as crested and gargoyle geckos enjoy the same type of environment but instead of day geckos being nocturnal, they are diurnal meaning they are active during the day time.

There are many substrates available for geckos, almost all being soil or natural fibre based. Which substrate you use is down to personal preference, don’t be afraid to try new things like mixing a couple of substrates together to get the perfect mix for your gecko.

Plastic plants or live plants can be used. Geckos require UVB. Although they often remain in the partial light, they do have access to sunlight in the wild and so we do recommend a UVB source. Heating should be provided in the form of a ceramic or heat bulb. This should maintain ambient temperatures with a hot spot for basking.

It is important to turn off lighting at night, and any heating which is used, so that your gecko can understand the natural light cycle and act accordingly. If you are not reaching the advised temperatures, speak to us about adding extra heating to your enclosure.

Always wash your hands before and after handling your day gecko.

Day Geckos are unlike the more common types of gecko kept such as leopard geckos, crested geckos and gargoyle geckos because they are very fast moving and generally do not like to be handled. If you do need to handle your gecko to move it, we recommend catching it against the glass with a clear plastic tub, ensuring the tail is not touched in any way. Day geckos, like many other species are able to drop their tales to avoid being caught by predators in the wild. Although the tail grows back, it does take some time for the tail to come back properly and will generally be dark or black for some time.

Day Geckos can be accurately sexed from around 6 months of age.

Like many other lizards, Male Day Geckos will have large femoral pores between their back legs. It is easier to sex Day Geckos using a clear tub and looking at the bottom of the lizard from underneath.

It is important to accurately sex your gecko before housing it, especially in a group enclosure.

As adults, females are slightly smaller than males but this should not be used as an accurate way to sex.

Eyes–  Eyes are clear with no eye caps. Sometimes with a dry shed, eye caps get stuck. To help get the shed off fully, you can set up a moist moss hide for your gecko. Use Beaphar skin and eye ointment for stuck caps and gently remove with a cotton pad, never try to peel off the eye caps.

Skin–  The skin is clear of shed and there are no cuts or scrapes on the geckos skin. Occasionally locusts or crickets can nip the skin of the gecko. Always remove live food that is not eaten after the geckos meal to prevent further bites and stress which can stop your gecko eating.

Limbs– All the limbs are moving correctly and the gecko is able to walk and move normally. Geckos can suffer from a condition called MBD (metabolic bone disease). This occurs when geckos do not have enough calcium and causes their bones to grow abnormally, eventually restricting their movements. MBD cannot be reversed so always dust livefood with calcium twice a week to avoid MBD occurring.
