pearl gourami or Trichogaster leeri
is a member of the family Belontiidae.
Pearl Gouramis inhabit the lowland swap waters of Sumatra,
Borneo, Malaysia and Thailand.
All gouramis belong to the
suborder Anabantid. The members of this
suborder evolved in poorly oxygenated environments. They subsequently
developed an auxiliary breathing apparatus in addition to their gills.
This lung-like organ, the labyrinth organ, allows them to breathe
atmospheric oxygen. At some point in the evolutionary process they
became dependent on both as a means of survival.
They will die without
a combination of dissolved and airborne oxygen.
This is why they are
frequently seen at the water’s surface.
the pearl gourami is a timid creature.
They are good additions to a community tank if they are provided with
plants, rocks and aquarium décor in which to hide. There
condition is a neutral pH with a water temperature around 78
length of approximately 5 inches and have a life expectancy of 5 years.
they tend to function better on a balanced
variety of tropical fish flakes and protein whether freeze-dried,
frozen or live.
dimorphic, meaning each sex possesses
traits specific to their gender such as size and coloration. Males are
typically larger and more colorful than females. The males also exhibit
an orange tinge to their fins with the exception of the tail fin. Males
have a bright orange region around their throat area. This distinctive
coloring is not present in juveniles. It develops as the fish reaches
sexual maturity. The color intensifies prior to spawning and is used to
attract the female of the species.
Gouramis have a
inclination to pair up. Gouramis spawn in
still water in their natural habitat. Turn the filter capacity in your
breeding tank down prior to spawning. The color of the male’s
region will indicate that he is ready to spawn. A sponge filter works
well to simulate mating conditions. And you have the added bonus of not
having to worry about the fry getting sucked up into the filter.
Provide plants for the breeding tank. The male will use his
labyrinth to build a bubble nest on the water’s surface. He
some of the provided plant matter to help the nest stay together.
Gouramis instinctively spawn underneath the bubble nest. Once
fertilization occurs, the male gourami will gather up the eggs with his
mouth and spit them into the bubble nest to mature.
Remove the female gourami from the breeding tank after they have
spawned. It is the male’s job to tend to the nest. He will
care for the eggs until they hatch. You will find the male a very
attentive custodian of his future offspring.
The fry will hatch in approximately 24 hours. They will be free
swimming in 2-3 days. It is now time to remove the male to insure that
he does not eat the fry. Once free swimming, the fry can be fed
infusoria, or rotifers. When they get about a week old feed them
powdered fry food, or newly hatched brine shrimp. An economical
alternative is powdered eggs. Make sure not to over feed the fry or you
will foul up the water in your tank.
