🐟 Peruvian Red Pencil Fish – Type II (Nannostomus mortenthaleri)

The Peruvian Red Pencil Fish – Type II is a rare and highly sought-after variant of the iconic red pencil fish, boasting slightly different patterning and coloration from the standard form. Native to the blackwater streams and tributaries of Peru, these fish are prized by aquarists for their vivid crimson bodies accented with deep black horizontal stripes.

Peaceful and small, they are ideal for nano and planted aquariums, where their striking colors truly shine against lush green plants. Best kept in groups of 8 or more, these fish become more confident and display more intense coloration in soft, slightly acidic water with gentle flow and subdued lighting.
