Discus

Symphysodon discus

The Discus fish is a vibrant and elegant freshwater species known for its distinctive round, disk-shaped body. Native to the Amazon River basin in South America, it is often considered one of the most beautiful aquarium fish in the world.


Discus fish have laterally compressed bodies and can grow up to 8–10 inches (20–25 cm) in diameter. They are famous for their striking colors and patterns, which range from bright blues and reds to yellows, greens, and intricate striped or spotted designs. Selective breeding has produced many stunning varieties in the aquarium trade.


They prefer warm, soft, slightly acidic water and thrive in temperatures between 82–86°F (28–30°C). Discus are peaceful and social fish, often doing best when kept in small groups. Due to their specific water requirements and sensitivity to changes in water quality, they are generally recommended for experienced aquarists.


In their natural habitat, Discus feed on small invertebrates, insects, and plant matter. In aquariums, they are typically fed high-quality pellets, frozen foods, and specially formulated diets to enhance their coloration and health.

Because of their graceful appearance, calm behavior, and vibrant colors, Discus fish are often referred to as the “King of the Aquarium.”
