Assessed as Vulnerable due to an inferred population decline of greater than 30% over the past ten years. This is as a result of habitat degradation and water pollution within the Kapuas River basin.
|Range Description:||This species is known only from the Kapuas River, in Kalimantan, Indonesia.|

|Population:||The population is thought to be decreasing at a rate of more than 30% over the previous ten years, although detailed numbers are not known.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||S. vaillanti is a benthopelagic species.|
In the last ten years, illegal gold mining in the Kapuas River basin has increased dramatically, and as a result, the Kapuas River is experiencing environmental problems due to poor mining practices. One of these problems is the increase of mercury pollution in the Kapuas River. So far, efforts to prevent water pollution and environmental destruction in the basin have failed, and the damage continues (Adijaya and Yamashita 2004).
In addition, freshwater habitats in Kalimantan are threatened by deforestation, conversion of land to agriculture, overfishing, the introduction of exotics and the aquaculture industry (WWF 2001).
|Conservation Actions:||There are no conservation measures currently known to be in action at habitat or species level.|
