Leopard geckos are docile reptiles with easy-care levels, making them among the most popular pet reptiles out there. They are hardy lizards with lots of interesting personalities. Leopard geckos are in demand due to their wonderful personalities, and you may be wondering if you can breed them in captivity.

Breeding of leopard geckos is an exciting process from the beginning to the end. Leopard geckos are among the easiest reptiles you can breed, but you will need to do a lot of research and prepare to help ensure your breeding pair is safe and happy.

In this article, we will provide you with enough information that you need to know to help make your leopard gecko breeding easy and successful.

Everything About Leopard Gecko Breeding

Generally, leopard geckos breed by the mating of the male and female. The female will then lay an egg that will then hatch into a hatchling. A fascinating thing about leopard gecko is that the temperature where the egg is kept will help to determine the sex of the hatchling leopard gecko.

Female leopard geckos usually lay their eggs under logs or rocks in the wild. The eggs are usually soft and will harden and develop a protective shell after some time. It will then take around 6-10 weeks before the eggs are incubated based on the temperature.

When Can Leopard Gecko Breed?

Just like other reptile species, the size and weight of a leopard gecko will determine its sexual maturity. Leopard geckos usually become sexually mature when they weigh around 35-40g between 18-24 months old.

Leopard geckos will start breeding if you keep a male with at least two females in an enclosure. Gecko owners can encourage breeding by shortening the day and reducing the gecko’s enclosure’s temperature zone to 70-75°F for 4-6weeks.

Breeding Season of Leopard Gecko

In the wild, the breeding season of leopard geckos usually starts in January or February and can last until September. Your female gecko will mate and lay eggs several times during the breeding season. However, leopard geckos can mate all year-round in captivity.

Since leopard geckos are crepuscular reptiles, they typically mate at night when they are active.

The Habit Of Finding A Mate And Mating

You can determine that your leopard gecko is about to breed when they start to circle each other. This is usually a short process and can take about 2-5 minutes. 

During courtship, the male leopard gecko will show interest in a female gecko by approaching it. The male will then circle round the female and will either lift up its tail or move it side to side. Once the male finishes inspecting the female and finds her desirable, it will dash towards her.

It is recommended that you monitor the courtship closely because leopard geckos can show aggression towards each other during the period. This can then cause severe injuries if you are not there to separate them.

As stated above, a male leopard gecko will rattle its tail when approaching the female. The female gecko will then turn and respond to the male’s advances. She will then freeze up and stare directly at the male when it is ready to mate. They will take some time to size each other up before the male stops rattling its tail to approach her quickly.

Whether it’s leopard gecko or any other gecko species, they mate in the same way.

The male will quickly climb on the female’s back and then bite her neck to position itself. It is normal for a male to bite, but you can separate the geckos if you notice any bleeding. After successful mating, the male will separate from the female, and you can place the geckos in a different tank.

However, if the female is not ready to mate, it will back away or attack the male aggressively.

Things You Need For Breeding Your Leopard Geckos

Although it is easy to breed a leopard gecko, breeding your leopard gecko is more than just placing a male and female together in an enclosure. This is because your gecko will need certain conditions and environments for the breeding to be successful.

In the section below, we will highlight the things that you need for breeding leopard geckos.

Selecting Leopard Geckos Breed

The first thing that you will need for breeding a leopard gecko is the breeding stock. You will need a male and 1-2 female leopard geckos that are completely healthy and in good shape for the breeding process.

You can also identify the male by the oval-shaped hemipenal bulges.

Tank For The Female Geckos

You can house a single female leopard gecko in a 10-gallon tank but using a 20-gallon tank is more comfortable. This way, it can be quite easy to introduce the male for mating and then return him to its enclosure.

However, if you want to breed more than a female, the tank should not be less than 20-gallon. This is because there should be space where your geckos can explore and hide. There should also be extra space for the time that you want to introduce the male.

Tank For The Male Geckos

The minimum tank size for housing a male leopard gecko is a 10-gallon tank. However, housing it in a 20-gallon tank is more suitable. It is recommended to house a male leopard gecko in another tank and then introduce it to the female tank for mating.

After mating, you can then return your gecko to its enclosure.
