Description
The Three-lined Pencilfish is a small, peaceful schooling fish characterized by three prominent horizontal stripes along its body and often red coloration on its fins. It thrives in well-planted aquariums with soft, acidic water, mimicking its natural blackwater habitats. This species is known for its shy nature and graceful swimming.
