10+ gallon for juvenile leopard gecko
20+ gallon for adult leopard gecko
As you might’ve guessed, your gecko's enclosure is pretty important. There’s quite a few options you have to pick from. The sizing is based on glass aquarium-style enclosures, however, plastic and wooden enclosures are also adequate. Simply find an enclosure of similar or larger sizing in the material of your preference!
For a single leopard gecko, many people say a 10 or 15 gallon enclosure is just fine. If you ask me, this is quite small for an animal that is frequently active throughout the night. I'm comfortable keeping an adult in a 20 gallon or larger. This allows for space to include all of the hiding places, and a temperature gradient leopard geckos will thrive the most with.
Can reptile enclosures be too large? Many people will say yes, but if you ask me, there is no limit as to just how large your animal's home can be. I did a video on this!
Can you keep leopard geckos? This is a tricky question. Firstly, right off the bat - male leopard geckos will almost always fight, potentially to the death. A male and female can also fight, and if the female survives, your male may eventually fertilize your female. If you're interested in breeding, hopefully you've already kept leopard geckos, and this may not be the guide for you.
What about two female leopard geckos? This is where it gets complicated. Although I have personally kept multiple pairs of female leopard geckos together, it's often more difficult than separating and keeping them in separate enclosures. For this reason, along with a few others, I no longer cohab. It's required that you keep extremely close attention to them, ensuring your two generally solitary animals get along. Even if they do seem to get along, something can happen down the road that puts one leopard gecko off, and results in a fight.
You'll also have more difficulty keeping track of their feeding and health, as you won't be able to differentiate who's poop is whose, along with how much one gecko ate, unless you feed them separately.
I go more into detail of my experiences with cohabitation, and my suggestions, in this video!
Leopard geckos spend a decent amount of their time sleeping, especially during the day, and deserve places to feel comfortable and hidden in. The general consensus is a single leopard gecko should have at least 3 hiding places. One in the warm area of the enclosure, another in the cooler area, and the final hide should be turned into a "humid hide". This final hide acts as moist place for your leopard gecko to shed its skin off. This should be kept moist at all times, as it's very hard to tell when leopard geckos are about to shed - and may go through the entire process before you even notice.
Can't find the shed? You shouldn't! As soon as it's pulled off, your gecko will snack on it, until the entirety of his or her old skin has been eaten. This re-uses the nutrient your gecko would otherwise lose, just leaving the shed to dry up. Recycling at its finest.
To create a humid hide, simply cut a hole into Tupperware, sand or melt the edges to avoid cuts or scratches, and add moist paper towel or coconut fiber to the interior. Keep it damp, and you're good to go!
