Redtail Licorice Gourami (Parosphromenus Ornaticauda)

Rare, vivid, and exquisitely beautiful — the Redtail Licorice Gourami (Parosphromenus ornaticauda) is a stunning and uncommon blackwater nano gourami from Borneo, prized for its vivid red caudal fin that blazes against its dark, iridescent body. A true jewel of the Parosphromenus genus and a prized species for specialist blackwater aquarists.

Overview

Appearance

The Redtail Licorice Gourami displays a dark, almost black body with iridescent blue-green body markings and a vivid red to scarlet caudal fin — the distinctive “redtail” that gives this species its common name. The contrast between the dark iridescent body and the vivid red tail creates a fish of extraordinary visual impact for its tiny size. Males in breeding condition display the most intense colouration, with the red tail appearing almost luminous under aquarium lighting.

Water Parameters & Tank Setup

• Temperature: 72 – 82°F (22 – 28°C)
• pH: 4.0 – 6.5 (very soft, acidic blackwater conditions essential)
• General Hardness (GH): 0 – 5 dGH (very soft water required)
• Tank Size: Minimum 10 gallons for a pair or small group
• Plants & Decor: Heavily planted with Indian almond leaves, driftwood, and leaf litter; dim lighting preferred; small caves or tubes for spawning

Diet & Feeding

• Staple: Live or frozen micro foods — baby brine shrimp, micro worms, daphnia, and infusoria
• Note: Very small mouths require appropriately sized micro foods; may refuse dry foods

Feed small amounts 2–3 times daily.

Compatibility & Tank Mates

Best kept in a species-only or carefully chosen blackwater nano tank. Avoid any boisterous or larger fish that may stress or outcompete them for food.

Breeding

Cave spawners — males guard eggs in small caves or tubes. Fry are tiny and require infusoria and micro foods.

The Redtail Licorice Gourami is a rare and exquisite nano fish that brings vivid red-tailed beauty and blackwater elegance to any specialist aquarium. A true gem for the dedicated enthusiast.
