|Scientific Name:||Sawbwa resplendens Annandale, 1918|
|Taxonomic Notes:||Endemic to Lake Inle, Shan State in Myanmar.|
|Red List Category & Criteria:||Endangered B2ab(iii,v) ver 3.1|
|Reviewer(s):||Allen, D.J. & Kullander, S.O.|
The species is only known from Inlé Lake in Myanmar, where it is impacted by introduced species of fish and a range of other threats. It is assessed as Endangered on the basis of a single location (major threat of introduced predators), restricted extent of occurrence, and a decline in population size as a result of the impacts of introduced species, suspected over-harvesting for the aquarium trade and the impacts of pollution. The area of open water in the lake has declined in recent years (Sidle et al. 2007), a situation that has been exacerbated by recent droughts (Htwe 2010). If the trend continues the species may qualify for a higher threat category.

|Habitat and Ecology:||Inhabits midwater and margins of the lake, and associated with submerged vegetation. Aggregates in small schools.|
|Use and Trade:||Popular in the aquarium trade, especially in the Japanese market.|
Regularly harvested for aquarium trade, which may have impact its population. The introduction of non-native (to the lake) fish species, including farmed species (e.g., the larger Parambassis spp.) and tilapine fish are the major threats, both as as predator and competitor. Some of the introduced native fishes access the lake as a result of raised water levels from the downstream dam.
Pollution from a range of sources impacts the lake; sedimentation and agricultural pollution from the surrounding drainage, as well as direct pollution inputs form the growing human settlements around the lake.
The area of open water in the lake has declined in recent years (Sidle et al. 2007), a situation that has been exacerbated by recent droughts (Htwe 2010).
|Conservation Actions:||Research into harvest and population trends is needed.|
