Description
The Oneline Pencilfish is a slender, peaceful freshwater fish known for its distinctive horizontal stripe running along its body. It typically inhabits slow-moving, heavily vegetated waters, often swimming at an oblique angle. These fish are best kept in schools of six or more to encourage natural behavior and reduce shyness.
