Blue Marble Gourami

The Three Spot Gourami Trichopodus trichopterus(previously Trichogaster trichopterus) was described by Pallas in 1770 and is found widespread throughout continental southeast Asia and Indonesia.

 

The Opaline Gourami is a captive bred color-morph of the Three Spot Gourami. Its history starts with an early variety known as the Cosby Gourami that was developed from the Blue Gourami by an american breeder named Cosby. Further developments of the Cosby Gourami became known as the Opaline Gourami or Marbled Gourami. The Opaline Gourami is now commercially bred in various color forms of its own.
