Can You Put Two Crested Geckos Together?

Many lizards are usually kept as pets, but few are as unique and attractive as the crested gecko. These lizards are striking in appearance and come in many different colors and variations. They are full of personality and make excellent pets, but once you get one, it tends to trigger a desire for more. The question is, can you put them all together, or do you need a separate terrarium?

But according to some reputable sources such as the Royal Veterinary College of the University of London, crested geckos are happiest when living alone. That doesn’t mean you can never keep these two lizards in the same house; it just means that you have to be very particular about how you do it.

In this article, we will discuss the risks of keeping crested geckos together and how you can reduce those risks to make them a more profitable option. We’ll also cover gecko pairs that have had the best and worst successes for a friendly life, ensuring you have a great chance of keeping two crested geckos together without major issues.

The Risks of Putting Multiple Crested Geckos Together

If you plan to try to house two crested geckos in the same cage, you should be aware of all the potential hazards that may arise as a result. This will ensure you’re prepared in case anything happens, and should offer the foresight needed to prevent many of these problems from appearing again.

Battle Between Lizards

The biggest risk when keeping several crested geckos in the same cage is fighting. The fights between these lizards can be very intense and aggressive. This often results in the death of one or both lizards. Injuries are almost guaranteed if such a conflict arises, and you can bet that some of those injuries will be quite serious.

Male crested geckos tend to be very territorial. That’s why they fought so intensely. But women are not the same. Women and men do not fight over territory. Males generally only attack other males in their space. For this reason, You will never want to keep two male crested geckos in the same cage. This will most likely result in a fight, which could result in injury or death for your gecko.


This may sound wild, but cannibalism is the main thing to consider. This is most common when there is a marked difference in size between two geckos in the same space. Larger lizards usually eat smaller lizards. In reality, crested geckos are voracious carnivores that will eat anything they can put in their mouths, and the smaller lizards just look like other food for one of these lizards.

Unfortunately, the problem of cannibalism does not end there. If a lizard is eaten, the lizard is lost. But what if the lizard that eats it chokes on a smaller lizard? Now you have two dead lizards, and this possibility is much more likely than you might think.

Potential Pair of Crested Geckos

To keep crested geckos together without fighting and running amok, you need to be very selective about the geckos you choose to house with. In this section, we’ll cover a few different pairs you might consider, and whether they’re a good idea or not.

Many boys

This may be the last pair you want to make with a crested gecko. Males can be very territorial, and if you put them together, you are more likely to see a fight, which could result in injury or death to one or both of the geckos.

Male and female

One male and one female can be placed together safely. This will likely produce offspring, but you may want to temporarily separate the two lizards after the female gives birth. She will need time to cool off and recuperate without the stress of the male trying to chase her to keep breeding.

Men and Some Women

This may be the best approach if you plan to keep more than one crested gecko in a cage. It is recommended that you keep no more than three in total to avoid fighting over space, even between females. But with one male and two females, there should be no fighting, lots of breeding, and the female will still get a cooldown time without being kicked out of the cage.

Some Women

Female crested geckos tend to form hierarchies when kept together, but they also generally remain peaceful. They are less territorial than males, and as such, are less likely to fight. You can usually safely hold several females together.

Crested Gecko Baby

Things are a little different when it comes to dealing with babies as they are a bit more social than mature adults. You can keep several baby crested geckos together without much risk of fighting, regardless of gender.

Keeping Crested Geckos Safely Together

If you are still determined to keep more than one crested gecko in a cage, then you should know how to do it in the safest way possible. Here are some tips to help you do that.

Only Choose Safe Partners

Don’t try to bring two men together, it’s not worth the risk. Stick to sensible groups. Keep no more than one male per cage. Females can be kept together, but make sure there is enough space to avoid fighting. One male can be kept with several females, but if he is being kept with just one, make sure he gets a separate cooldown time from him after giving birth.

Choose a Lizard of the Same Size

The last thing you want to do is accidentally feed the smaller crested gecko to the larger gecko by trying to squish them together. Avoid this by only placing lizards in the same habitat if they are about the same size. Even if the lizard doesn’t eat the smaller lizards, the larger males may try to breed with the unprepared female, causing serious damage in the process.

Ensure Spacious Space

Even female crested geckos will fight with each other if they don’t have enough space. You’ll want a 20 gallon tank for at least one crested gecko. Two geckos will require a 30-gallon terrarium, and more geckos will require more space. Keeping too many geckos in too small a space is a quick way to start causing trouble among your lizards.



Crested geckos make great pets and they are some of the most unique looking lizards. Keeping geckos in the same cage seems easy, but you need to be very careful about pairing them unless you want the lizards to kill or injure each other. However, if you take reasonable precautions such as never keeping many lizards together and only keeping lizards of the same size together, you should be able to keep several lizards in the same habitat safely and peacefully.
