Aquarium: A 24" (61 cm) or 10-20 gallon (38-76 L) tank is adequate for a single pair.
least a 20 gallon (76 L) is recommended for more.
Arrange the tank in dark colors with a cover of floating plants.
tank should be well-planted along the edges, and an open swimming area should be left in the center.
a retreat for each fish.
Like all Labyrinth fish, the Pearl Gourami prefers shallow tanks.
Water chemistry: pH 5.5-8 (7.0), 2-30 dH (8), 75-86°F (24-30°C)
Social behavior: The Pearl Gourami will be harassed, stop eating, and loose color if combined with aggressive
species (cichlids). Otherwise an excellent community fish. Males may harass females during the spawning season.
this occurs, separate the pair because the male may injure or kill the female.

Suggested companions: Danios,

that can tolerate neutral water conditions.
FOOD: Live; Tubifex
, insects, insect larvae, crustaceans; flakes; pellets; chopped spinach and lettuce
Sexual differences: The males are more colorful and have pointed dorsal fins.
Breeding techniques: The water level should be reduced 4-6" (10-15 cm) and no water current should be
Condition the pair with insect larvae,
The male builds a large bubble nest
(occasionally over 10" in diameter) at the water's surface in floating plants.
After an active courtship, 200-300 clear
eggs are laid.
Spawning may continue for extended periods-even weeks.
These float up to the bubble nest, and
are corralled by the male.
They are guarded by the male.
At this time, all other fish should be removed, including the female.
eggs hatch after 20-30 hours.
The fry remain in the nest for 4-5 days.
Start feeding with paramecia, roftiers, and infusoria.
male can be removed after the fry are free-swimming.
The fry are slow-growing.
Breeding potential: 7.
Breeding is moderately difficult due to the difficulty in finding a suitable pair.
a pair is found, spawning comes fairly easily.
Like other Gouramis, the Pearl Gourami possesses taste cells at the
tips of the ventral fins.
Remarks: The Pearl Gourami regularly lives over 8 years.
