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 100 litre or larger tank with water approximately 30 cm 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 colour and may refuse to eat if kept with overly aggressive fish. It is easy to tell the male from the female because he has extended, pointed dorsal and anal fins, and is more red.
Prior to breeding, the pair should be fed live or frozen brine shrimp and worms for conditioning. The water temperature should also be raised to 27°C. When breeding, the water level in the tank should be reduced to 4-5 inches. The male will build a bubblenest under which spawning will take place.
After spawning the female should be moved to a separate tank. The male Pearl Gourami tends to the eggs, and once the fry are hatched, the male should also be removed. The fry should be fed liquid food or infusoria culture several times a day.
At approximately two weeks, freshly hatched (or frozen) brine shrimp may be offered to the fry. When the fry reach approximately one month, fine flake foods may be offered. Water should be changed every two to three days, and as the fry grow larger, they should be distributed between several tanks to reduce lethal build up of wastes.
