The fish, up close
The Tandanus catfish, scientifically known as Tandanus tandanus, is a freshwater catfish native to Australia. These catfish are easily recognised by their long, slender bodies and prominent barbels around their mouths. They have a mottled brown or olive colouration, which helps them camouflage among riverbeds and sandy substrates. Their dorsal and pectoral fins are equipped with sharp spines for defense. Tandanus catfish are bottom-dwellers, often hiding in caves or under driftwood during the day and becoming more active at night.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Tandanus catfish are generally peaceful and solitary fish. They are nocturnal by nature, so they are most active during the night. These catfish are bottom-dwellers and spend much of their time scavenging for food along the substrate. They may become territorial towards their own species or other bottom-dwelling fish.
Tank planning
Provide Tandanus catfish with plenty of hiding spots such as caves, driftwood, and plants in the aquarium. Maintain good water quality with regular water changes as these catfish are sensitive to poor water conditions. Avoid keeping them with aggressive or overly active tank mates that may stress them out. Regularly monitor their diet to ensure they are getting proper nutrition.
