Marbled Geckos

Note: I will no longer be breeding these geckos so that I can focus on terrestrial species. I still know a lot of breeders and importers however, so let me know if you're looking for one.

These beautiful arboreal geckos are native to Australia. They generally have a tan or olive colored body with lighter and darker blotches giving them a marbled appearance. Like Tokays and other tree loving geckos the marbled geckos can climb the walls of their cages, making a well secured or locking lid a necessity.

A tall 20 gallon aquarium is the minimum recommend size for one of these geckos as the males can reach eight or more inches long and the females are only a little smaller. If you want to house a male with your female you’ll need to increase the cage size up to at least 55 gallons. Lots of branches and hiding places towards the top of the cage will give your geckos a sense of security.

They need a daytime temperature of 75 to 85 degrees F and a night temperature of around 70 to 75 degrees F. If you have breeding females due to lay soon I’d maintain a standard cage temperature of 80 degrees F until the eggs have been safely laid and collected for incubation. Humidity levels should be maintained at about 75% and can be helped by placing a large shallow water dish in their cages and daily misting. The geckos will not likely use the water dish, but will get the water they need from the misting.

I use a combination substrate of Bed-a-Beast mixed with Reptile Bark. This combo seems to help keep the cage humidity up without becoming smelly or too wet.

Dusted and gut loaded insects are the best food for Marbled geckos although I’ve heard of owners offering them baby food. Crickets are the best if your geckos are good eaters. If they’re picky or thin I’d recommend using waxworms as they have a higher fat content and are pretty much “candy” for geckos. Large adult males may eat small pinkie mice, but they’re hard to gut load so it’s difficult to supplement them. 

(Note: The above little girl is very thin as she is a recent import and needs to put weight on!)




If you decide to breed your geckos you've really got to monitor them closely because they may not get along and will often fight to the death. Putting the male into the females cage or both into a neutral cage may help a little, but if a territorial dispute arrises, make sure that you have gloves and are quick on your feet.

Eggs should be incubated at 80-84 degrees Fareinheit. If they're fertile the eggs may hatch anywhere from 65 to 200 days after their laid. If you can't remove the eggs from their parents cage than tape ventilated deli cups over them to prevent the adults from eating the hatchlings. Remove the hatchlings as soon as possible into their own individual grow boxes.
