A planted tank is an aquarium that features live aquatic plants alongside fish and other aquatic creatures. These tanks are designed to create a natural environment, promoting the health and well-being of the inhabitants. The plants help maintain water quality by absorbing carbon dioxide and releasing oxygen, which benefits both the flora and fauna. Setting up a planted tank requires careful selection of plants, substrate, and lighting. Common plants include Java Fern, Anubias, and Amazon Sword. Proper maintenance, such as regular pruning and fertilization, is essential to keep the plants healthy and thriving in the aquatic ecosystem.
