Lined day geckos are small species that are found in the islands surrounding Madagascar. They are identified primarily through their green skin colors that are dotted with red spots all over their backs and in between their eyes and nose.

They got their namesake from the stripes that can be seen beginning from their nose and extending both to the sides of their bodies up to their tails and to the end of their legs. These stripes are colored yellow, black, and white, while their tails are colored in vibrant blue.

Lined day geckos can reach the lengths of 4.5 inches up to 6 inches, depending on which subspecies.

According to the IUCN’s Red List, they have a wide distribution and a large and stable population. They are listed as a species of least concern regarding extinction.

Lined day geckos are very adaptable animals and can enjoy living in man-made enclosures. As long as they receive adequate care, they can live an average of 10 years, or even longer, in captivity.

Availability and Natural Habitat

Lined day geckos are native to Northern Madagascar, Eastern Madagascar, and the Mascarene Islands of Reunion. They prefer living in banana plants, bushes, trees, and palms throughout the villages and rainforests.

While some of these geckos are being imported, there is a huge number that is bred in captivity.

Unlike other lizards, lined day geckos are active during the daytime, thus, their name. The males are very territorial and can even fight with their mates. They also enjoy climbing and hiding around.


The small lined day geckos feed on the most commonly available feeder insects, which are mainly composed of hornworms, reptiworms, crickets, roaches, silkworms, waxworms, and mealworms. 

In captivity, you can also provide your pet with commercially made gecko diets. 

Eating Habits

As a lined day gecko keeper, you should strive to offer variety into the diet of your pet. This would allow them to receive the different nutritions that come from consuming various feeder insects. If you can’t do this, supplementation using a reptile multivitamin and combine them with reptile calcium supplements is how you can provide your pet with their nutrient needs.

For egg-laying females, include calcium supplements during every feeding time. For the others, you can feed them with calcium every other feeding. For the vitamins, they can be offered to the animals at least once a week.

Common Health Problems

Geckos routinely shed their skins as part of their growth cycle. If they are having trouble with shedding, it is a sign that there are unhealthy. This can be part of living in unsanitary conditions, having incorrect humidity in the enclosure, and feeling stressed.

Also, they can get parasitic infections. If you are suspecting that your pet gecko might have a parasitic infection, this can be detected through a fecal exam. 

Lastly, one of their common problems is a metabolic bone disease. This is a serious illness that can affect many reptiles and is involved in vitamin D and calcium deficiency. This leads to weaker bones, which is very painful for the gecko. This can be a fatal illness if not treated right away.


Owning a beautifully colored lined day gecko will tempt you to try and touch them. Unfortunately, the lined day geckos are extremely sensitive, and they can easily be stressed, so no matter how much you want to, you should refrain from handling them.

Additionally, if they are handled too roughly, their skin can easily tear off, and they can even drop their tails. Although the regeneration of their tails is possible, they will not appear identical to their original tails, so it is still better to treat them cautiously.

Try to limit the handling into teaching your lined day geckos to take food from your hands. With patience, you can train them about this and familiarize them with your presence.

Though lined day geckos are fairly small, this does not mean that they are housed in a small area. For one adult, the ideal enclosure size must be 12 inches by 12 inches by 18 inches. They thrive on large terrariums, but you can also use the traditional glass aquarium. These animals are quite busy and have high levels of activity, so if you can provide a larger one, that would be better. If you are interested in breeding them, you can house a male and a female in 18 inches by 18 inches by 24 inches cage.

Now, for the design and decoration of the cage, always put first the knowledge of your lined day gecko’s natural behavior. Since they are relatively small, you can provide them with foliage to burrow under and some spaces to use as hiding boxes. These geckos also enjoy climbing, so you can also provide them with elevated hide boxes. Most experts suggesting the use of bamboo hollows and zoomed cork rounds, as the lined day geckos will treat them like how they would hug and lie down some round tree branches.

Also, lined day geckos will appreciate cylindrical basking perches that they can use whenever they feel threatened to hide on. You can also opt for installing wood products, magnetic ledges, grapevines, and cork flats.

With regards to plants, aside from providing a great natural look to the cage, they also increase humidity in the cage and provides a beneficial microclimate that your lined day geckos need so that they can stay healthy. There’s no need to worry about them eating the leaves, as they do not have interests in plants that way. You can place any type of plant that you desire, but your best choice will be plants that have high moisture levels and typically thrive in tropical environments.


The substrate for a lined day gecko enclosure would be dependent on the type of living space that you can provide for them. One set up that your geckos will surely like is a naturalistic vivarium with living plants inside. It also looks aesthetically pleasing, which is a big bonus for your lined day gecko.

When going for a naturalistic vivarium, the substrates that you will need are polyfoam, hydroton balls, and a mix of eco earth and moss growing substrate. Polyfoam will act as a divider between planting layers and drainage layers, while hydroton balls will be used for the drainage. Additionally, combine a healthy mix of moss growing substrate and eco earth to provide the live plants in the enclosure some beneficial nutrients.

If you just plan on using artificial plants, you can benefit from a substrate that is easy to clean and that can retain humidity well. You can take your pick from compressed coconut husk, eco earth, orchid bark, and cypress mulch. Any of these would be great for your pet day gecko, so you can play around and experiment on which one would work best.

Lighting and Temperature

Lined day geckos can achieve their beautifully vibrant colors with the use of high-quality lights. Heating and lighting are essential for these reptiles, and without them, their skin will turn dark and drab. No matter how colorful they were when you got them, they will lose their beauty if you don’t provide them with these needs.

For lighting, you can use a basic fluorescent strip lighting and combine it with a basking light or a halogen light. This is usually the best way to go for lined day geckos, but make sure that you go for lower wattage basking bulbs, especially if you are using a smaller cage.

Observe the temperatures in the cage, and they must remain around 90 degrees Fahrenheit for the basking spots and around 70 degrees Fahrenheit towards the cool side of the cage.

If you have decided to house your lined day geckos in larger terrariums, you can use a mercury vapor bulb for extra heating. It also produces lots of UVB light for your lined day gecko’s needs. The large amount of UVB can provide your geckos the brightest skin color through these lights.

Humidity and Water

Lined day geckos are tropical species, and they should be provided a tropical environment, even in captivity, so that they can survive. To keep humidity, you must mist them at least twice a day so that the humidity will be increased. Misting would also provide them with water droplets on the leaves that they can use for drinking.

Additionally, you should add a clean water bowl with fresh water, just in case they want a soak or if they want to use it for drinking. Don’t forget to replace the water regularly to avoid contamination.

On the other hand, you can use a terrarium fogger, instead of mist spraying every day. Aside from being aesthetically pleasing, these fogger machines increase humidity naturally, and the fog produces condensation in the leaves for your geckos.
