Threespot Gourami Trichopodus trichopterus

The Threespot (Three Spot, Three-spot) Gourami is native to slow or still, marshy water of Indochina, particularly the Mekong basin, and Indonesia, but it has been introduced to other areas. It migrates to flooded grassland and forest in the wet season. Its natural colour is a blueish grey and it grows to 15cm. It has only two spots on each flank.

In aquaculture, it has been bred in several colours (blue, gold, amethyst, white) and a marbled pattern called Cosby or Opaline. The Three-spot Gourami is a bubble nester. The male builds a bubble nest for the female to lay eggs, which he then guards aggressively (even from the female).
