Sparkling Gourami Care Guide - Aquarium Setup, Diet & Breeding

Sparkling Gourami are tiny, beautifully marked labyrinth fish with a brown to golden body covered in iridescent blue-green spots. Their translucent fins may show red, blue or gold tones, while a dark horizontal stripe runs along each side. Despite their small size, they have an eye-catching jewel-like appearance under aquarium lighting.

This species is also known as the Pygmy Gourami and, like other members of the genus Trichopsis, can produce a faint croaking or clicking sound. The sound is created by the pectoral fin muscles and is most often heard during courtship, territorial displays or moments of excitement.

In nature, Sparkling Gourami live among dense aquatic vegetation, floating plants and submerged roots. They are adapted to calm, oxygen-poor environments and can breathe atmospheric air using their labyrinth organ, allowing them to survive in habitats where dissolved oxygen levels may fluctuate.

They are generally peaceful but have lively individual personalities. Sparkling Gourami spend much of their time exploring the middle and upper areas of the aquarium, pausing among plants and showing subtle displays toward one another. Males may establish small territories, particularly when courting or guarding a bubble nest.

Sparkling Gourami originate in mainland Southeast Asia, including Thailand, Cambodia, Laos and Vietnam. They inhabit shallow, slow-moving and often densely vegetated waters such as marshes, rice fields, pools and sluggish streams.

A group of Sparkling Gourami should have at least a 45-litre aquarium, with a footprint of roughly 60 × 30 cm or larger preferred over a tall, narrow tank. Use a mature, tightly covered aquarium with gentle filtration and subdued flow. Dense planting, floating plants, fine-leaved stems, shaded areas, driftwood and small caves provide security and help divide territories. A dark sand or fine-gravel substrate complements their colours, although the substrate itself is not demanding. Leave some open access to the surface because they regularly breathe atmospheric air, and keep the cover secure above the waterline.

Sparkling Gourami reach a maximum adult length of around 4 cm (1.6 inches). Males are usually slightly larger and more slender than females, although individual size varies.

Sparkling Gourami are small omnivores with a preference for meaty foods. Offer a varied diet of high-quality small granules or flakes supplemented with baby brine shrimp, daphnia, cyclops, mosquito larvae and other appropriately sized frozen or live foods. Feed small portions once or twice daily, making sure every item is tiny enough for their small mouths. Newly hatched fry require fine first foods such as infusoria or a suitable commercial fry food.

Sparkling Gourami suit peaceful community aquariums with similarly small, non-aggressive fish. Good companions include chili rasboras, small peaceful rasboras, ember tetras, pygmy Corydoras, kuhli loaches and other gentle Southeast Asian or South American nano species. Avoid fin-nipping fish, boisterous tankmates and large predators, as well as aggressive gouramis, bettas and other territorial anabantoids. Keeping them with calm fish that do not monopolise the surface gives this shy species more confidence.

Sparkling Gourami are bubble-nest breeders. Provide broad leaves or floating plants near the surface, along with gentle flow and warm, slightly acidic water. The male constructs a small bubble nest, courts the female beneath it and gathers the eggs after spawning, then guards the nest until the fry become free-swimming. Remove the female after spawning if necessary, and feed the tiny fry infusoria or other suitably fine foods before moving them on to newly hatched brine shrimp.

Males are typically slimmer, with a more extended and pointed dorsal fin and stronger colouration, especially during courtship. Females are usually rounder through the abdomen, particularly when carrying eggs, and often have a shorter, less pointed dorsal fin.
