Description
The Empire Gudgeon (Hypseleotris compressa) is a striking and robust freshwater fish native to Australia and parts of Papua New Guinea. Commonly found in slow-flowing rivers, creeks, estuaries, and billabongs, this species is well-suited to both freshwater and brackish environments. The male Empire Gudgeon is especially admired for its brilliant red-orange fins and iridescent blue-green body patterning, which becomes most vibrant during the breeding season. Hardy, adaptable, and peaceful, the Empire Gudgeon is an excellent addition to native community aquariums or species-specific setups.

The best aquarium size for Gudgeon Empire Hypseleotris compressa

Aquarium Setup Gudgeon Empire Hypseleotris compressa
Aquarium Filtration
Moderate filtration with gentle flow is ideal. Use sponge filters or canister systems with flow diffusers to maintain oxygenation while mimicking natural conditions.
Aquarium Plants
Provide dense planting along tank margins using species such as Vallisneria, Java Fern, or native Australian aquatic plants. Floating plants can offer cover and help diffuse lighting.
Aquarium Lighting
Moderate to bright lighting brings out the male’s colouration. Ensure shaded areas with plant cover to allow retreat from direct light.
Aquarium Heating
Keep water temperature between 22–28°C. This species adapts well to seasonal fluctuations but prefers stability during breeding.
Aquarium Substrate
Use fine sand or smooth river gravel to mimic natural riverbeds. A dark substrate enhances the visual contrast of their bright fin colouration.
Aquarium Decorations
Include driftwood, rocks, and submerged branches to establish territories and provide shelter. Ensure all hardscape materials are smooth and aquarium-safe.
