The Pearl Gourami is a peaceful fish that is also known as the Leeri or Lace Gourami. It is one of the most attractive, hardiest, and easy-to-keep gouramis. The body is stretched out and laterally compressed with ventral fins that are long and thin, having the look of feelers. It is covered with iridescent pearl and brown flecks that give it a mother of pearl appearance. There is a horizontal black line that runs from the lips to the tail, where it ends with a spot. The Pearl Gourami is a Labyrinth Fish. Fish in this group breathe directly from the air and must have access to the surface of the tank.The Pearl Gourami requires a 30 gallon or larger tank with water approximately 12 inches deep, and a covering of floating ferns that may be used as hiding places. The substrate should be dark and the light subdued. The ideal tank mates for the Pearl Gourami would be similar in size and temperament. They should not be housed with aggressive tank mates, like Cichlids. They will hide in a corner, begin to loose color and may refuse to eat if kept with overly aggressive fish.
