Willang
Tandanus bellingerensis — known as the Willang — is a small freshwater catfish with a naturally restricted range in coastal river systems of eastern Australia.
A member of the eel-tailed catfish family (Plotosidae) and closely related to the better-known freshwater catfish of the region, it remains one of the least-documented species in the genus.
Published angling and biological records are sparse, and most practical knowledge comes from what is understood about closely related Tandanus species sharing similar habitat.
Scientific Name: Tandanus bellingerensis
- A Plotosidae catfish with the family's characteristic tapering body and continuous fin that wraps around the tail — the feature that gives the group the name 'eel-tailed catfish.'
- Like other Tandanus species, almost certainly carries sharp pectoral and dorsal spines — use a wet cloth or jaw grip when handling to avoid punctures.
What to know
Habitat Distribution
- A naturally restricted species tied to the Bellinger River system and a small number of nearby coastal drainages in eastern Australia — one of the more range-limited members of its genus.
- As a Tandanus catfish in subtropical coastal river country, it is associated with slow to moderate freshwater reaches, lowland pools, and waterways with soft or mixed substrate.
Specific Spots
- Slow, deeper sections of river with soft substrate and overhead cover — submerged timber, undercut banks — are where related Tandanus species concentrate, and the Willang almost certainly follows the same pattern.
- Rocky or mixed-bottom areas near slower current provide both shelter and foraging ground; these transition zones between hard and soft substrate are worth working after dark.
Willang FAQ
Answers from onWater's species guide.
What are the best lures and bait for Willang?
Natural baits, cut fish, mussel flesh, and earthworms presented on the bottom, are the documented approach for related Tandanus catfish in similar river systems; no Willang-specific bait records exist to suggest otherwise.
What do Willang eat?
No species-specific diet data exists for the Willang; based on closely related Tandanus catfish, the likely forage is bottom-dwelling invertebrates, mollusks, and small crustaceans, which points toward natural baits like worms or mussel flesh presented on or near the substrate.
Where do Willang live?
A naturally restricted species tied to the Bellinger River system and a small number of nearby coastal drainages in eastern Australia, one of the more range-limited members of its genus.
