The Pearl Gourami is not only one of the most attractive gouramis, but also one of the hardiest and easiest to keep. It is also a Labyrinth fish, meaning that it is able to breathe by gulping air at the surface of the tank. Like some other Labyrinth fish, the Pearl Gourami can actually vocalize; don't be surprised if you hear your pet "talking to you" with growling or croaking noises (especially when breeding or fighting).
This species originates in Thailand, Malaysia and the islands of Borneo and Sumatra. They prefer acidic water found in lowland swamps near the sea. Some Pearl Gourami have been introduced in Singapore and Colombia. It's rare to find a wild Pearl Gourami for sale as an aquarium fish; most are bred in captivity.
