Discus

About

Discus (Symphysodon discus) are the round, laterally compressed showpieces of the Amazon basin, and few freshwater fish carry themselves with quite the same presence. Wild fish are found in calm, darkly stained waters near the mouth of the Negro River and in the lower stretches of the Abacaxis and Trombetas rivers in Brazil. Slow, warm, acidic environments that this species has adapted to over millions of years. The body is almost perfectly disc-shaped, and between the vivid color forms developed in the hobby and the natural wild variants, the visual range is genuinely impressive. In the wild they are opportunistic feeders, picking at worms, small crustaceans, insects, and plant material along the riverbed and margins. In the aquarium they are peaceful fish that do best in groups and can become surprisingly personable with regular human interaction, often recognizing their keeper at feeding time. Despite being listed here as beginner-friendly, that label deserves a caveat. Discus are sensitive to water quality and do best when their keeper pays close attention to consistency. They reward patience and careful husbandry with long lives and behavior that few other freshwater fish can match.
