Also known as: Trichopsis pumila

The Sparkling Gourami (Trichopsis pumila) is a diminutive labyrinth fish known for its iridescent blue-green body and delicate, flowing fins. The Sparkling Gourami originates from Southeast Asia, specifically Thailand, Cambodia, Vietnam, and Laos, inhabiting slow-moving, vegetated waters such as swamps, rice paddies, and ditches., reaches Adult size: 3.5 cm in captivity, typically lives Typically 3 to 5 years under optimal aquarium conditions., and is kept at 22–28°C (72–82°F); stable temperatures within this range are essential for health and breeding.. Individual fish vary, so treat this as a general guide rather than a guarantee.

Species at a glance

Origin: Southeast Asia, specifically Thailand, Cambodia, Vietnam, and Laos, inhabiting slow-moving, vegetated waters such as swamps, rice paddies, and ditches.
Adult size: Adult size: 3.5 cm (1.4 inches) in length.
Life span: Typically 3 to 5 years under optimal aquarium conditions.
Temperament: Peaceful and shy; best kept in small groups of 4-6 individuals; males may display mild territorial behavior during breeding but rarely aggression.
Tank size: Minimum 20 liters (5 gallons) for a small group; 30+ liters (8+ gallons) recommended for better stability and natural behavior.
Water temp: 22–28°C (72–82°F); stable temperatures within this range are essential for health and breeding.
pH range: pH 5.0–7.5; prefers soft, slightly acidic to neutral water but adapts to a wide range if changes are gradual.
Diet: Omnivorous; feeds on small invertebrates, zooplankton, and insect larvae in the wild; in captivity, accepts high-quality micro pellets, frozen or live daphnia, brine shrimp, and bloodworms; supplement with blanched vegetables like spinach or zucchini occasionally.

About the Sparkling Gourami

The Sparkling Gourami (Trichopsis pumila) is a diminutive labyrinth fish known for its iridescent blue-green body and delicate, flowing fins. Native to Southeast Asia’s shallow, vegetated waters, it thrives in densely planted aquariums with subdued lighting and gentle flow. Males produce faint croaking sounds during courtship, a trait unique among gouramis. Despite its small size, it exhibits complex social behaviors and is highly sensitive to water quality fluctuations.

Lifespan and health

With proper care, Sparkling Gouramis commonly live 3–5 years, though exceptional specimens may reach 6 years in pristine, low-stress environments; longevity is heavily influenced by stable water parameters, minimal aggression, and a varied diet rich in protein. Common health issues include bacterial infections (often from poor water quality or injury), fungal infections on fins, and parasitic infestations like Ichthyophthirius multifiliis (Ich), which manifests as white spots and lethargy—treat promptly with elevated temperature (28–30°C) and appropriate medication; avoid overcrowding and sudden pH shifts to prevent stress-induced immunosuppression.

Overview

Care and tank setup

Tank setup should prioritize dense planting with species like Java moss, Anubias, or floating plants such as Salvinia to provide cover and reduce stress; use a dark substrate and include driftwood or leaf litter to mimic natural tannin-stained waters. Filtration must be gentle—sponge filters are ideal—to avoid strong currents that can exhaust these small fish; maintain zero ammonia and nitrite, with nitrates below 20 ppm through weekly 20% water changes. Feed small amounts 2–3 times daily, offering only what they can consume in 2–3 minutes to prevent overfeeding and water pollution; vary diet with live or frozen foods 3–4 times weekly for optimal coloration and health.

Adding a Sparkling Gourami? Research the species’ adult size and temperament carefully, quarantine new fish before introducing them to your tank, and buy from reputable aquarium stores or breeders.
