Tupong

Tupong (Pseudaphritis urvillii)

The Tupong, also known as the Congolli, is a hardy, bottom-dwelling species native to the estuarine and freshwater systems of southeastern Australia and Tasmania. As a temperate fish with an amphidromous life cycle, it can tolerate a range of salinities, making it suitable for carefully maintained brackish or freshwater aquaria. Known for its cryptic colouring and ambush-hunting behaviour, the Tupong appeals to aquarists seeking an unconventional native species that displays intriguing ecological adaptations.

The Best Aquarium Size for a Tupong

A single adult Tupong requires an aquarium of at least 200 litres to allow for appropriate swimming space and environmental complexity. As a solitary or loosely territorial species, additional individuals require significant additional space and visual barriers to reduce stress.

Tank Mate Compatibility for Tupong

Tank mates must be robust, temperate-water species that do not compete aggressively for the same benthic niche. Suitable companions include:

• Southern pygmy perch

• Australian smelt

• Gudgeons (e.g., empire gudgeon)

• Murray rainbowfish

• Fly-specked hardyhead

• Western galaxias

Avoid small, delicate species or those requiring tropical conditions.

Diet for a Tupong

A carnivorous predator, the Tupong requires a diet rich in protein. Feed:

• Live or frozen invertebrates (bloodworms, brine shrimp, blackworms)

• Small fish or shrimp (as occasional treats)

• Sinking carnivore pellets or soft-frozen foods formulated for benthic predators

Feed 34 times weekly; avoid overfeeding to maintain water quality.
