Description
The Australian Grayling (*Prototroctes maraena*) is a slender, silvery fish native to the cool, clear rivers of southeastern Australia. This diadromous species is known for its distinctive cucumber-like smell and its migratory lifecycle between freshwater and estuarine environments. It is a protected species, highly sensitive to habitat disturbance, and not typically found in the aquarium trade.
