The Flame Gourami, also known as the Flame Dwarf Gourami and officially named Trichogaster lalius, is a member of the family Osphronemidae. This is an artificially bred variety, which appeared as a result of long and purposeful cross-breeding of various species over many generations. The goal of such selection was to fix a special coloration that truly makes an impression: a bright fiery body combined with a blue dorsal fin makes this fish a wonderful decoration for any home aquarium. In addition, it is characterized by good hardiness.
