There is no hard and fast number of gecko hides you need for your tank. However, there are a few useful rules of thumb to consider. First, you should absolutely include hides in your tank so your gecko has a place where they feel safe and secure. Next, you also need at least one hide that includes a moist substrate, such as wet moss or a moist paper towel, so your leopard gecko can more easily shed their skin. The more leos you have, the more hides you should include in the tank so that all your pets have their own unique places to go. Finally, consider the size of your tank and the look you want to create. Placing leopard gecko caves, rocks, plants and other types of décor can increase the visual harmony of your habitat and make it more pleasant to watch your leos go about their lives. You can find all the supplies you need to care for your pet at Petco’s leopard gecko shop.
