Aquadecor Classic rocks aquarium backgrounds have become an absolute customers’ favorite over the past few years. A large variety of designs and colors, as well as their natural look, is what makes them ideal for Tanganyika and Malawi cichlids, or any other species that have rocks as a part of their natural habitat. We recommend classic rocks aquarium backgrounds (A models) for smaller, medium-sized and larger fish tanks. These backgrounds come in several pieces for a simple and easy setup and need to be glued to the glass using silicone for aquariums. They can be accompanied by the bottom and overhanging rocks in the same design and color. Each aquarium background can be made in any color.
