Aquarium plants are aquatic vegetation that can be grown in fish tanks to enhance the environment for both fish and plants. They provide oxygen, improve water quality, and offer hiding spots for fish, which can reduce stress. Common types of aquarium plants include Java Fern, Anubias, and Amazon Sword. These plants can be either floating, submerged, or emergent, depending on their growth habits. Proper lighting, substrate, and nutrients are essential for their health. Additionally, aquarium plants can help control algae growth by competing for nutrients, making them beneficial for maintaining a balanced ecosystem in the tank.
