Decorating your leopard gecko terrarium is more than just another means to waste your money and/or make your gecko’s space look prettier. While they can serve an aesthetic function, they also enhance a reptile’s quality of life by mimicking their natural environment and providing mental stimulation. The best zoos do this all the time — it’s called environmental enrichment. A common misconception is that reptiles are stupid creatures that don’t need “toys” or decorations beyond their keeper’s fancy, so modern reptile husbandry experts are working to disprove this.

Hides: A leopard gecko needs at least two hides: a warm, moist hide, and a cool, dry hide. Do not limit yourself to two hides, however. If possible, add more — like a warm, dry hide. People like having options, and leopard geckos do, too.
Plants: There’s not a lot of plants in leopard geckos’ natural environment, but if you want to enhance the aesthetic with fake plants, I won’t stop you. Avoid using real plants, as they can raise humidity.
Rocks: Since the substrate won’t be very naturalistic, one of the best ways you can improve the enclosure’s appearance will be with rocks. Leopard geckos like climbing, and in fact, stacking pieces of slate with inch-two inch spacers between simulates the cracks that they hide and climb in in their natural environment.
Backdrop: If you’re using an all-glass enclosure, adding a naturalistic backdrop can be much more attractive. It also helps the gecko feel more secure in its environment because he can’t see outside as much.
Water bowl: Geckos drink readily from water bowls, so they need on in their enclosure. It should be shallow enough that the gecko can’t drown by accident, and the water should be replaced daily.
Keep in mind that changes in décor may disorient or otherwise stress your gecko, making them act weird. This is normal for a week or two after major changes, but varies according to gecko. If your gecko doesn’t mind or seems to like change, then that might be a good way to enhance their environment. If your gecko reacts poorly to change, it’s best to keep the layout the same (however boring you might think it is).
