Overview

Appearance

The Blue Dwarf Gourami displays a vivid, intense blue colouration across the body, often with subtle iridescent highlights that shimmer under aquarium lighting. The long, thread-like pelvic fins trail gracefully below the body. Males display the most intense blue colouration, while females are more subdued. Under aquarium lighting, the vivid blue body creates a striking, jewel-like presence in any planted tank.
