Nannostomus beckfordi
Beckford's Pencilfish is a small freshwater fish with a slender elongated body. It lives in rivers and streams of South America and is often found in aquariums due to its calm temperament and beautiful coloration.
Beckford's Pencilfish helps control the population of insect larvae in water bodies. In nature, it serves as prey for larger fish, and in aquariums, it remains a popular peaceful species.
