Choosing the right 3D aquarium backgrounds for your fish tanks or terrariums can be a fairly difficult task. There are many things to consider before trying to make a choice such as the type of fish or reptiles you’re keeping, the type of habitat they prefer and of course, the size of your tank.

Rainforest 3D Aquarium BackgroundsRainforest BG

If you think rocky 3d aquarium backgrounds are a little too plain or boring for your taste, or if you keep animals which enjoy trees within their habitat such as most types of tropical fish and amphibians Рthis rainforest background is a great choice. Combined with a few plants and forest-themed decorations such as hollow logs or mossy stones, it will make your aquarium come to life.

It is constructed from a hybrid industrial-grade foam, making it completely safe and non-toxic. Like all other foam backgrounds it can easily be trimmed to fit any aquarium quite easily. The only drawback is that the average width of this background is about 3 inches, therefore a tank of 8+ inches in thickness is ideal.

Sizes available: Smallest size available is 24 x 16 inches, while the largest size available is 72 x 24 inches, with many other sizes in between.
