Aquadecor professional 3D rubber backgrounds are incredibly lifelike, durable, and made by hand with precision. Specifically made to fit snugly in most 90 gallon aquariums (but can be cut to fit), these rubber backgrounds sink and do not need to be siliconed in place, making installation simple and easy on both dry and already set up aquariums. They are also flexible and can bend to fit past an aquarium with a center brace, preventing the need for a two piece background that leaves an unsightly straight line down the center of the aquarium. They also allow water to flow around the background, permitting the placement of heaters, filters, and other equipment behind the background where they are out of sight and do not detract from the display. Each individual background is hand made, and therefore unique even within the same model, so you will receive a one-of-a-kind masterpiece! These backgrounds are not painted; the rubber is infused with pigment which means no color flaking or scratching off during maintenance. These backgrounds carry a Lifetime Warranty that offers full replacement by Aquadecor. Measuring 48" x 24".
