The Pearl Gourami (Trichogaster leeri), sometimes known as the leeri, is a tropical labyrinth fish often bred and kept for aquaria.
Distribution and habitat
The pearl gourami originates from Thailand, Malaysia, Sumatra, and Borneo. It occurs in lowland swamps with acidic water. This fish prefers the top and middle levels of the water.
Appearance and anatomy
These fish reach about 12 centimetres (5 in) TL. The body is a brownish-silver colour, covered in a Pearl-like pattern with a distinct black 'lace' running from the fish's head, and gradually thinning towards the caudal fin. The patterning of this fish has given way to many popular names, such as the Lace Gourami and the Mosaic Gourami. The 'lace' refers to the long black line running through the fish's body, whereas 'Mosaic' refers more towards the pearl, or mosaic-like patterning of the body.
Male specimens of this fish, typical of many Gouramis, are generally larger and more colourful than their female counterparts. They exhibit bright orange colouring around the throat region, which at breeding time becomes much brighter and is used to court the female. Males also exhibit somewhat of an orange tinge in their fins, with the exception of the caudal fin. The male also has longer fins, with a pointed dorsal fin and extended anal fin rays.
In the aquarium
Tank Requirements
A tank with a volume of 60 litres or over should do a pair of Pearl Gouramis fine, although anything above that volume is greatly recommended. The tank should be heated to around 22???28°C (72???82F). The tank should also preferably have a surface which is exposed to fresh air so the Pearl Gourami's labyrinth organ can function correctly. As with any tropical aquarium, provide adequate filtration, lighting, substrate and decorations, plants, and proper care. The Pearl Gourami is a peaceful fish well suited to most community tanks. However, this fish may be somewhat timid or shy, and should not be kept with fish that are too boisterous or aggressive. Keep the tank clean as this fish, although somewhat hardy, can be vulnerable to disease. Many Gouramis feel more at home when the tank is furnished with many plants, decorations, and ornaments which provide safe refuges for the fish in times of stress.
Feeding
The Pearl Gourami is an omnivore. It is best fed a good variety of flaked foods, freeze-dried foods such as tubifex worms, and the occasional safe live foods such as Daphnia, brine shrimp, and bloodworm.
Breeding
The Pearl Gourami is a bubble nest builder that uses plants to help bind together the bubbles. The water level should be reduced to 8 in during spawning, and the temperature should be approximately 28 °C (82 °F) and with a pH of around 7. After spawning the female may be left with the male. The male will tend to the eggs and fry, and when the fry are 2-3 days old the male should also be removed. When first hatched, the fry should be fed infusoria, and later, brine shrimp and finely ground flakes. Freeze-dried tablets may also be fed to older fry.
