Instructions
Purchase a minimum of a 25 gallon tall terrarium with a securely fastening screen. This size terrarium will safely house a pair of geckos.
Fill the terrarium with a few inches of coco fiber substrate, and add plenty of plants, logs, climbing branches, and hiding places. The more secure your geckos feel, the more likely they are to reproduce.
Place a 75 Watt basking heat lamp over one side of the tank, making sure the geckos can move in and out of the warm zone as they desire.
Maintain a humidity level between 70 and 90 percent through the day, and a high temperature of 75 to 80 degrees Fahrenheit. A spray mist bottle works well for keeping the humidity up, and live plants can help hold moisture in the terrarium as well.
Obtain a true male and female pair of geckos. This can be difficult to do without purchasing from a reliable breeder, as many pet stores have no idea how to accurately sex geckos, and the task can be difficult without one of each gender to compare to. If you have to purchase geckos from pet stores, look up images of male and female geckos online to learn the differences. The most obvious way to tell is by observing the vent areas: males will have wider tail bases and two nubs of flesh off of each side of the tail. Males are also often larger, and have two crescent-shaped areas of more pronounced scales forming a V near the vent.
Feed the geckos a variety of mineral dusted insects, such as crickets, waxworms, moths, locusts and grasshoppers. You can also occasionally supplement bits of fresh mashed fruit, which some white line geckos love.
Wait for the male and female to settle in and notice each other. White line geckos will generally breed every 4 to 6 weeks if conditions are right. The female will lay a clutch on the glass. The eggs can be fragile, so do not try to remove them. They can take between 90 and 140 days to hatch in the tank.
Watch the parents closely for signs of aggression. Most white lines actually protect the young during their early months, but some may opt to eat them instead. If aggression results, remove the babies to a separate enclosure.
Feed the offspring wingless fruit flies and pin crickets until they are old enough to begin accepting larger food.
Breeding White Lined Geckos
White line geckos, also commonly known as skunk geckos, are a 7 to 8 inch long species of Indonesian gecko named for the pale cream or white line which runs down their backs. While they are not nearly as common on the pet trade as leopard or even crested geckos, they seem to breed readily if conditions are appropriate. Your best chance for breeding white line geckos is to make sure they are happy and healthy, and let nature take its course.
