Tocantins ’24K gold’ Giant Talking Catfish (Megalodoras cf. uranoscopus)


A unique and heavily armored catfish found throughout the Amazon and its tributaries, the Giant Talking Catfish or Irwin’s Catfish is typically a gentle giant in the aquarium, ignoring most fish and being well protected from even the most aggressive tankmates. Although most specimens are tan or grayish in coloration, the specimens from the Tocantins River in Brazil are prized for their vivid yellow or gold colors against high contrast black. In the wild, their diet largely consists of aquatic snails, crustaceans, fruit and vegetation, but they will readily accept almost any sinking food. A great scavenger to help manage leftover food in large cichlid or predatory fish displays, they do grow to a huge adult size and will require a tank of 180 gallons at the bare minimum.
