The pearl gourami (Trichopodus leerii) is a species of gourami native to Southeast Asia. [2]
It reaches about 12 centimetres (4.7 in) TL. [2] Its body is a brownish-silver colour, covered in a pearl-like pattern with a distinct black line running from the fish's head, and gradually thinning towards the caudal fin. The pearl gourami's appearance has given rise to other popular names, such as the lace gourami and the mosaic gourami.
Its male specimens, 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. [3]
The pearl gourami is native to Thailand, Malaysia and Indonesia (where it is found on the islands of Sumatra and Borneo). It occurs in lowland swamps with acidic water. [2]
Trichopodus leerii was originally described as Trichopus leerii by the Dutch medical doctor and ichthyologist Pieter Bleeker in 1852. The type was collected at Palembang in Sumatra, [4] by Lieutenant-Colonel J. M. van Leer, who was a medical colleague of Bleeker's and whom Bleeker honoured in the fish's specific name. [5]
The three spot gourami, also known as the opaline gourami, blue gourami, and gold gourami, is a species of fish native to southeastern Asia, but also introduced elsewhere. This gourami gets its name from the two spots along each side of its body in line with the eye, considered the third spot. This species is of minor commercial importance as a food fish in its native range and is also farmed. It is also popular in the aquarium trade. The species reaches 15 cm in standard length.
Nanochromis transvestitus is a sexually dimorphic cichlid endemic to Lake Mai-Ndombe in the Democratic Republic of the Congo where they live at a depth of around 1 metre (3.3 ft). It feeds on small benthic invertebrates. This species reaches a length of 3.4 centimetres (1.3 in) SL. Unusually for cichlids, it is the female, not the male, that is the most colourful. The female has a vertical black and white banding on her anal and caudual fins, with a bright red abdomen. The male, by contrast, is grayish in colour. Like many cichlids, the male does, however, have longer anal and caudal fins. The fish are egg layers and make a nest in the substrate in which to lay their eggs. This species is particularly threatened by the practice of using mosquito netting to catch fish out of the lake as material with holes that small catches every species of fish in the lake regardless of size. The specific name is a derived from the Latin trans meaning "cross" or "over" and vestitus meaning "clothed", a reference to the reversal of the normal sexual dimorphism in that this species has drabber males and more colourful females.
