The Pearl Gourami (Trichogaster leeri), sometimes known as the leeri, is a tropical labyrinth fish often bred and kept for aquaria. 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. These fish reach about 12 centimetres. 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 rise 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 (tail) fin. The male also has longer fins, with a more pointed dorsal fin and extended anal fin rays.
