Tandanus Catfish 3.5cm

Tandanus Catfish

The Tandanus Catfish, also known as the Eel-Tailed Catfish, is probably Australia's most famous and popular native catfish species. This is such a fascinating and unique species which really should be way more popular worldwide. They are a great alternative to some the tank buster catfish available in the hobby and have a much more peaceful demeanour. Aside from being a popular aquarium fish amongst predator and native aquarium keepers, these are a great aquaponics, sports and table fish as well.

Tandanus Catfish have a sleek, elongated body that can grow up to 60 cm in length, making them suitable for large tanks. Their coloration ranges from brown to dark grey, often with a mottled pattern that provides excellent camouflage in their natural habitat. The long, slender tail is reminiscent of an eel, giving this catfish its common name. This species is awesome for larger community systems due to its ability to coexist with a variety of tank mates, making it a versatile choice for community aquariums given it has enough space.

Breeding Tandanus Catfish in the home aquarium is uncommon but not impossible. They are egg layers, typically spawning in nests created by the male. Providing a spacious tank with plenty of hiding spots and a sandy substrate can help encourage breeding behaviours. The male will guard the eggs until they hatch, displaying a level of parental care that is quite rare among catfish species. Males and females though do not have any dimorphic traits, so the hope is to have a large enough aquarium with a few catfish and letting them pair off naturally.
