Providing housing for a reptile in general is usually a pretty common and easy task but it’s really easy for crested geckos. They don’t require a lot of special or expensive equipment, as long as you keep them warm and continue to feed them; they’ll be content with you. Geckos are very versatile and they have to be because of their size. In the wilderness they have to be fast and versatile if they want to escape some of the predators that lurk out there in the jungle.
The numbers of enclosures that a Gecko can safely be kept in is limitless but if you want the most common option that is easiest to take care of then get a cage or aquarium to store the Gecko or Geckos in.
TIP: NEVER EVER put males together in the same cage or same place at the same time. Like two drunken guys at a bar, they will fight because they’re very territorial. While you can add a lot of landscaping or textures to make it more realistic like they’re back in their own natural environment, they can survive in simplistic conditions as well and it doesn’t have to be the most decorated thing in the world.
It’s recommended that hatchlings be placed in a 10 gallon aquarium or tank at minimum. However, you should monitor the youngest ones because if you put them in a larger housing structure, then they might stop eating or not eat at all. It’s a common issue to know that some of the younger geckos when placed in larger houses don’t eat too well. This doesn’t happen to all of them but it’s a known and common issue. They seem to have trouble adapting to the size of the housing.
So for safety sake, it’s best to keep any young hatchling that’s less than 12 weeks in old in an aquarium that’s not any bigger than 10 gallons.
There’s a lot of debate on whether or not that adult Geckos will do just fine in a 10 gallon aquarium but it’s highly recommended that you put them in something a little larger such as a 20 gallon aquarium at minimum so they have the ability to be mobile and have more room. They aren’t going to stop eating if they’re put in a larger tank and they like to be active. They won’t have a lot of leg room if they’re stuffed into a 10 gallon aquarium tank. For example, if you have two to four adults, then you should have no problem putting them into a 30 gallon tank/aquarium.
Make sure that you have a screen cage in case you owner other curious pets that might try to get into the cage and this also helps with keeping the humidity up inside the structure as well. Make sure that there’s adequate height as well because it’s easier to maintain efficient temperatures in well-rounded containers and adult Geckos seem to prefer those habitats more.
