Why Do I Need A Background For My Aquarium? It's important for your aquarium to mimic your fishes' native habitat as closely as possible to keep them happy.

In addition to adding caves, vases, and other decors for your pets, a background covering one or maybe two sides of your tank is essential.

Without a background, your fishes will see their reflection and this can cause stress and aggression. How Do I Apply Jor's Dual-Sided Solid Background? Dual-Sided Solid background is easy to apply.
