Yellow Fin Hillstream (Pseudogastromyzon viriosus)

Yellow Fin Hillstream, scientifically known as Pseudogastromyzon viriosus, is a unique freshwater fish admired for its flat body shape, bright yellow fins, and ability to cling to rocks and aquarium surfaces. This fascinating hillstream loach is popular among aquarists who enjoy unusual species with interesting natural behaviors.

Pseudogastromyzon viriosus comes from fast-flowing streams in Asia and prefers a well-oxygenated aquarium with strong water movement, smooth rocks, and a clean environment that mimics its natural habitat. It feeds mainly on biofilm, algae, and specialized foods designed for bottom-dwelling fish.

With its peaceful temperament, attractive appearance, and active grazing behavior, Yellow Fin Hillstream is an excellent choice for planted river-style aquariums. Providing stable water conditions, good filtration, and plenty of surfaces for grazing will help this species thrive.
