Screwsnout

Screwsnout is a term primarily associated with the *Screwsnout* species of freshwater fish, scientifically known as *Cyclocheilichthys armatus*. This species belongs to the family Cyprinidae and is native to Southeast Asia, particularly in the Mekong River basin, including countries like Thailand, Laos, Cambodia, and Vietnam.

The fish is named for its distinctive elongated snout, which resembles a screw or corkscrew, giving it its common name. This unique feature aids in its feeding habits, allowing it to scrape algae and organic matter from hard surfaces like rocks and riverbeds. Screwsnout is a popular aquarium fish due to its striking appearance, peaceful temperament, and adaptability to various water conditions. It typically grows to about 15–20 centimeters (6–8 inches) in length and exhibits a silver-gray body with a dark lateral stripe running along its sides.

In the wild, Screwsnout inhabits slow-moving rivers, streams, and flooded forests, where it thrives in slightly acidic to neutral water with moderate flow. It is an omnivorous species, feeding on algae, detritus, and small invertebrates. Due to its role in maintaining aquatic ecosystems by controlling algae growth, it is considered beneficial in natural environments.

While not currently listed as endangered, overfishing and habitat destruction pose potential threats to its populations. In aquaculture, Screwsnout is sometimes bred for the ornamental trade, though it remains relatively rare compared to other popular cyprinids. Its care requirements in captivity include a well-filtered tank, hiding spots, and a diet supplemented with algae wafers or vegetable matter.
