General Description
The Shortfin Tandan (Neosilurus brevidorsalis) belongs to the family Plotosidae within the order Siluriformes. With a maximum size of 20.0cm, this species has a relatively small dorsal fin, as indicated by its specific epithet "brevidorsalis". Its type locality is Nicol Bay in Cape York, Queensland, Australia, and its distribution is restricted to northern Australia, particularly the Jardine and Jackson river systems on the Cape York Peninsula, and southern Papua New Guinea.
Aquarium Setup
For housing a Shortfin Tandan, a tank size of at least 270 litres is recommended. The water parameters should fall within a temperature range of 20-28°C, a pH range of 6.0-7.5, and a moderate hardness level of 36-268ppm.
Behaviour
Shortfin Tandans are known for their relatively calm and solitary nature, often seeking out hiding spots within the aquarium environment. They may display some territorial behaviors, especially during breeding periods.
Feeding and Diet
In their natural habitat, Shortfin Tandans are carnivorous, feeding on small invertebrates, crustaceans, and fish. In a home aquarium, they typically accept live and frozen foods such as bloodworms, brine shrimp, and blackworms.
Reproduction & Dimorphism
Details on the reproduction and dimorphism of Shortfin Tandans are limited, but it is known that they are egg layers. Males and females may exhibit slight differences in size and coloration, with females potentially being larger and rounder.
Habitat and Distribution
Within their confined distribution range, Shortfin Tandans inhabit freshwater environments such as river systems and drainages. They are native to the northern regions of Australia, particularly the Cape York Peninsula, and parts of southern Papua New Guinea, including the Fly River basin.
