To create a natural aquarium environment that ensures proper oxygen for your fish, use natural substrates like sand or gravel, and add live aquatic plants such as Java Fern and Anubias, which release oxygen during photosynthesis. Include elements like driftwood, rocks, and caves to mimic natural habitats and provide hiding spots. Install a reliable filter for clean water and gentle circulation, and use an air stone or pump for additional aeration. Maintain optimal lighting for plant growth and ensure stable water temperature suited to the fish species. Avoid overcrowding, perform regular water changes, and promote surface movement to enhance oxygen exchange and maintain a balanced, natural ecosystem.
