[Ebook] The New Guide to Aquarium Fish – Anabantids – Gouramis
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.
