Once seen, a large mature male Pearl Gourami in full breeding regalia is never forgotten. This is another of those “must-keep” fish. A golden form appeared in outdoor ponds in Florida in the early 1990s, but the colors faded and were replaced by normal wild-type coloration over a period of a few weeks once the fish were transferred to indoor aquaria.
By far and away the most popular group of fishes among the anabantids are the gouramis belonging to the family Belontiidae. Of these, members of the genus Trichogaster, such as Trichopterus sumatranus (Blue gourami), Trichopterus microlepis (Moonlight gourami), and Trichopterus leeri (Pearl gourami), are probably the easiest fishes to keep because they are tolerant of most water conditions.
