About the Empire Gudgeon

The Empire Gudgeon is one of Australia's most colourful native freshwater fish, admired for its iridescent blue-green body, golden highlights, and brilliant orange to red fin margins. Native to the rivers and streams of northern and eastern Australia, this peaceful species has become increasingly popular among aquarists looking to showcase Australian native fish.

Empire Gudgeons thrive in well-planted aquariums with driftwood, rocks, and plenty of shaded areas. Males develop the most vibrant colours during breeding, displaying brilliant metallic blues and greens that rival many tropical species. While generally peaceful, they can become mildly territorial when spawning, particularly around caves and nesting sites.

This species is best kept in pairs or small groups and mixes well with other Australian natives and peaceful tropical fish of a similar size. A varied diet of quality micro pellets, frozen bloodworms, blackworms, brine shrimp, insect larvae, and live foods will keep them healthy while enhancing their spectacular colouration.

With their fascinating behaviour, hardy nature, and stunning appearance, Empire Gudgeons are an outstanding choice for both native and planted freshwater aquariums.

Common Mistakes

Not providing enough hiding places

Driftwood, caves, rocks, and dense plants help reduce stress and encourage natural behaviour.

Housing with aggressive fish

Choose peaceful tank mates that won't outcompete or bully these native fish.

Feeding only dry foods

A varied diet including frozen and live foods helps maintain vibrant colours and breeding condition.

Poor water quality

Stable water conditions and regular maintenance are essential for long-term health.

Keeping them with very small fish

Although generally peaceful, they may consume tiny fish or invertebrates that fit into their mouths.
