Common name: White Cloud Mountain Minnow
available through www.itis.gov
Native Range: First discovered at White Cloud Mountain (also known as Mount Baiyun or Baiyunshan) a few miles north of the city of Guangzhou, Guangdong Province, China and thought to be restricted to the surrounding Pearl River Delta region. Unfortunately it has probably been extirpated from that locality; the “mountain” is actually a collection of 30 or so peaks and is now a very popular tourist resort complete with cable car access, hotels, and public parks. Between 1980 and 2001, the species went unrecorded in nature, leading to fear of its extinction (Seriously Fish, 2012b).

Ecology: This species inhabits clear, slow-moving brooks with thick weed growth (Chan and Chen, 2009). The White Cloud Mountain minnow is cold water tolerant fish often kept in aquaria. Although the nominal temperature range for the species in the wild is 18–22 °C, it can survive water temperatures down to 5 °C (Froese and Pauly, 2012). It feeds on plankton, meiobenthos and larvae of aquatic insects. This species spawns several times a year, from March to October, on plants (Cui, 2011).
Means of Introduction: Aquarium release.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
