Giant Gouramis originate from swamps, lakes and rivers in
India, Thailand and Myanmar. They are the largest of all gouramis.
They are known by the scientific name Osphronemus goramy, but another smaller
species known by the scientific name Colisa fasciata is also called the Giant
Gourami. The latter is also called the Banded Gourami, Rainbow
Gourami, or Striped Gourami. It is much smaller than
Osphronemus goramy, being about 5 inches long, and is closer in resemblance to
the Dwarf Gourami.
When young Giant Gouramis are golden with banding, as in the picture
above. At around 3 - 4 years of age they darken to grey or almost black
and develop swelling of the forehead, known
as a nuchal hump. The anal fins are large and rounded and they have the
distinctive elongated pelvic fins typical of gouramis. The body is very
narrow in width. In Thailand, this species is caught as a sport fish.
Giant Gouramis can breathe moist air, so they can survive for extended periods out of water.
They enjoy floating plants and plant cover. A very large tank will be
necessary due to the large size of this fish. Many species typically
compatible with other gouramis will be too small for a tank containing Giant
The dorsal fin on the male ends is more pointed and the coloring of the male
becomes darker during spawning. The male has thicker lips during
breeding and will build a bubblenest when ready to spawn. For breeding,
the water in the tank should be decreased in depth and the
temperature should be at the upper end of their range. The female should be removed
after spawning. The eggs will hatch in 24 hours. The fry should be fed infusoria and then
