Licorice Gourami 2cm

The Red Pencilfish (Nannostomus mortenthaleri) is one of the most strikingly coloured nano fish available in the hobby, originating from the Río Nanay in Peru. Males display an intense, deep red body with bold black and white lateral striping — a combination that makes them truly stand out in a planted aquarium. They are a peaceful, slow-moving species that thrives in soft, acidic blackwater conditions.
