Liquorice Gourami "Linkei"

Liquorice Gourami "Linkei" (Parosphromenus linkei)

The Liquorice Gourami "Linkei" is a rare and exceptionally beautiful nano labyrinth fish, prized for its intricate patterning, iridescent blue-green highlights, and elegant finnage. Native to the blackwater peat swamps of Borneo, this captivating species is highly sought after by experienced aquarists who appreciate its subtle beauty, fascinating breeding behaviors, and peaceful nature. Its small size and remarkable coloration make it a true gem in specialized planted and blackwater aquariums.

Liquorice Gourami "Linkei" are shy, peaceful fish that thrive in calm environments with minimal competition. They spend much of their time exploring among leaf litter, mosses, and dense vegetation while searching for tiny food items. Males develop more intense coloration and display elaborate courtship behaviors, particularly during breeding, while females exhibit softer, more subdued colors. Their gentle disposition makes them best suited to species-only aquariums or carefully selected communities with other small, non-aggressive fish.

These delicate gouramis require mature, heavily planted aquariums with soft, acidic water, subdued lighting, and plenty of natural hiding places. Driftwood, botanicals, floating plants, and leaf litter help recreate their natural blackwater habitat while providing security and encouraging natural behavior. As labyrinth fish, they breathe atmospheric air and require unobstructed access to the water's surface. They prefer a diet of small live and frozen foods such as baby brine shrimp, daphnia, microworms, and finely sized prepared foods to maintain optimal health and coloration.
