Marble Gourami, Gold-Orange Form (Trichogaster trichopterus)

31 October 2026

108

The marble gourami is a selectively bred color form of the three-spot gourami, a labyrinth fish from mainland and island Southeast Asia. The supplied trade label identifies these fish as a gold-orange pair, although commercial names and appearance can vary, so the exact cultivated form is not fully certain. They are generally hardy community fish, but males may become territorial, especially when spawning. Provide warm, stable water, surface access, dense planting, and gentle filtration.

Marble Gourami, Gold-Orange Form (Trichogaster trichopterus)

Taxonomy and identification

The supplied source identifies this fish as Trichogaster trichopterus, commonly called the three-spot gourami. Aquarium literature also commonly uses the name Trichopodus trichopterus for the same species. Marble, opaline, gold, and related names describe selectively bred aquarium color forms rather than separate species. The trade description indicates a gold-orange form, but the exact strain cannot be confirmed from the supplied material.

Natural distribution and habitat

The species is native to freshwater habitats in Southeast Asia, including parts of the Mekong and Chao Phraya regions and the Malay Archipelago. It occurs in slow-moving or still water such as swamps, marshes, canals, ponds, rice fields, and vegetated margins. These habitats can be warm, quiet, shallow, and periodically low in dissolved oxygen.

Behavior and appearance

Three-spot gouramis use their modified pelvic fins as tactile feelers and regularly breathe atmospheric air through a labyrinth organ. They usually occupy the middle and upper levels of the aquarium. Females are often fuller-bodied, while mature males tend to have a longer, more pointed dorsal fin. Males may defend surface areas and become more assertive during breeding.

Aquarium and tank size

A pair should have at least about 120 litres, with a larger, longer aquarium preferable for long-term stability and territorial separation. Use a secure lid, open access to humid air above the water, gentle circulation, floating plants, rooted cover, and clear swimming space. Avoid strong currents and sudden temperature changes. Maintain mature biological filtration and perform regular partial water changes.

Water parameters

Keep the water stable at 24-28 °C and pH 6.0-8.0. Soft to moderately hard water is suitable, although this adaptable species can tolerate a broader mineral range when acclimated gradually. Ammonia and nitrite should remain undetectable, and nitrate should be kept low through maintenance. Stability is more important than pursuing a precise numerical value.

Diet

Offer a varied omnivorous diet based on a quality small or medium-sized tropical pellet or flake. Supplement it with frozen or live foods such as bloodworms, brine shrimp, daphnia, and mosquito larvae where legally and hygienically appropriate. Small portions given once or twice daily are preferable to overfeeding. Occasional vegetable matter can be included, particularly in planted community aquariums.

Compatibility

Suitable companions include peaceful, similarly sized community fish that do not nip fins or compete aggressively at the surface. Avoid housing them with persistent fin-nippers, highly aggressive cichlids, or very boisterous species. Adult males may harass females or subordinate gouramis, so dense plants and visual barriers are important. Observe individual behavior because temperament varies.

Breeding

The male builds a floating bubble nest, often among floating plants, when conditioned with warm, clean water and abundant live or frozen foods. Spawning occurs beneath the nest, after which the male may guard the eggs and repair the nest. Remove the female if she is being persistently chased, and consider moving the male after spawning if he threatens her. Fry are very small and require infusoria or another suitably fine first food, followed by progressively larger foods as they grow.
