Banded Gourami (Trichogaster fasciata)

Trichogaster fasciata, the Banded Gourami, is a striking and somewhat underappreciated species within the gourami family, native to the river systems of Bangladesh, India (particularly the Ganges and Brahmaputra basins), Myanmar, and Pakistan. Despite its beauty, it is less commonly seen in the aquarium trade than the Pearl or Dwarf Gourami, making it a rewarding find for enthusiasts seeking something distinctive.

Males display vivid alternating bands of metallic blue-green and orange-yellow running vertically across the body, complemented by an orange-red belly during spawning condition. The fins are elaborately patterned and the ventral fins are modified into long thread-like feelers characteristic of the genus. Females are less boldly coloured, displaying a more muted banded pattern on a silver-olive body.

Like all Trichogaster (previously Trichogaster) gouramis, T. fasciata is a labyrinth fish — equipped with a specialised breathing organ that allows it to extract oxygen directly from atmospheric air. This adaptation makes it tolerant of low-oxygen environments and is the reason gouramis periodically visit the water surface to gulp air.

The Banded Gourami is generally peaceful with other species but males can be aggressive toward each other and toward other gourami species, particularly in small tanks. A single male with two or three females in a well-planted aquarium makes an ideal setup.

Tank Setup: A minimum 80-litre tank for a single male with females. Provide dense planting with floating plants (Frogbit, Amazon Frogbit, or Water Lettuce) to diffuse surface light and provide shelter. Driftwood and caves create territory boundaries. Low to moderate water flow — labyrinth fish prefer calm surfaces to build their bubble nests.

Water Parameters: Temperature 24–28°C; pH 6.5–8.0; GH 5–18 °dH; KH 3–10 °dH. Adaptable to a broad range of conditions. In very warm, oxygen-poor water, the labyrinth organ compensates — still maintain good filtration.

Feeding: Omnivore. Accepts quality flake food, pellets, frozen bloodworm, brine shrimp, Daphnia, and small amounts of blanched vegetables. Feed two to three times daily. Tends to be surface and mid-water feeder.

Tank Mates: Peaceful with most fish that don't resemble other gouramis. Good with tetras, rasboras, corydoras, smaller barbs, and livebearers. Avoid other male gouramis in the same tank and fin-nippers like Tiger Barbs.

Behaviour: Males are labyrinth fish that build floating bubble nests in calm surface areas, especially under floating plants. During spawning, males are more aggressive toward females after egg deposition — provide retreat hiding spots for females.

Health: Hardy once established. Susceptible to velvet and ich under stress. Avoid cold draughts near the tank surface — cold air above the water can damage the labyrinth organ. Maintain warm, stable conditions.
