Silver Perch

About the Silver Perch

The Silver Perch is one of Australia's most iconic native freshwater fish, valued for its peaceful temperament, rapid growth, and hardy nature. Native to the Murray-Darling River system, this attractive species features a streamlined silver body with subtle bronze and olive tones that become more pronounced as the fish matures.

Silver Perch are highly adaptable and thrive in ponds, aquaculture systems, and large freshwater aquariums with excellent filtration and plenty of swimming space. They are naturally inquisitive and quickly become confident around their owners, often recognising feeding times and readily accepting prepared foods.

As omnivores, Silver Perch enjoy a varied diet including quality native fish pellets, vegetables, aquatic plants, insects, worms, and frozen foods. Their peaceful disposition allows them to coexist with other suitably sized Australian native fish, making them a popular choice for native display aquariums and outdoor ponds.

Due to their potential adult size, Silver Perch are best suited to spacious aquariums or ponds where they have ample room to grow and thrive.
