Blue Panaque (L239) – Midnight Blue Elegance

The Blue Panaque (L239), also known as the Blue Panaqolus, is a sleek and uniquely colored pleco prized for its dark navy-to-steel-blue sheen. Its smooth body, subtle armor, and elegant shape make it a standout in any aquarium, especially under soft lighting where its blue tones truly shine.

Native to fast-flowing rivers in Venezuela, the L239 prefers well-oxygenated water, moderate current, and plenty of hiding places such as driftwood and rockwork. Though shy and reclusive, it is peaceful and generally compatible with other non-aggressive tank mates. This species feeds primarily on vegetable-based foods and biofilm, but will also accept algae wafers and soft vegetables.
