Discus

The Discus (Symphysodon sp.)

The King of the Aquarium

Experience the pinnacle of the freshwater hobby with the Discus. Often heralded as the King of the Aquarium, no other fish commands attention quite like a fully mature Discus. With their massive, flattened, disc-like bodies and graceful demeanor, they bring an unparalleled elegance to large, low-light biotopes. Whether you prefer the intricate, maze-like patterns of "Leopards" and "Snakeskins," the solid, striking pigments of "Marbled Whites," or the fiery intensity of "Red Melons," these fish are living art.

Pro-Tips for Success (Crucial for Discus)

Discus are not community fish for a standard setup. They are high-maintenance "divas" that require pristine water parameters. Because of their preferred high temperatures, they need a dedicated large filtration system and very frequent water changes (up to 50% weekly or even twice weekly). They must be kept in groups of at least 6 to prevent extreme stress and shyness. We highly recommend using a RO/DI water system to manage their soft, acidic requirements.

Aquarist Note: Discus are highly sensitive to nitrate. If you cannot commit to rigorous maintenance and a specialized feeding regimen, this is not the species for you. They should only be kept with very docile, heat-tolerant tankmates.
