Discus fish are often regarded as the “kings” of the freshwater aquarium. Native to the slow-moving waters of the Amazon Basin in South America, Discus are known for their round, disc-shaped bodies, striking color patterns, and elegant swimming style. Their vibrant hues range from brilliant blues and reds to yellows and greens, making them one of the most sought-after species in the aquarium hobby. An interesting fact about Discus fish is their unique parental care. Unlike many other fish species, Discus parents produce a special mucus on their skin that their fry feed on during the early stages of development. This provides essential nutrients and helps the young fish grow strong and healthy. Watching this nurturing behavior in a home aquarium is a rewarding experience for any Australian aquarist.
