Blue panchax
The blue panchax or whitespot is a common freshwater fish found in a large variety of habitats due to its high adaptability. This species is native to southern Asia from Pakistan, India, Malaysia to Indonesia. It has been discovered in two hot springs in Singapore. The species also commonly spotted in Johor Bahru rivers and estuaries. Identified by a white-coloured spot on its head, the species can reach up to 9 cm in length; it tends to keep to the surface of the water, and controls the mosquito population by feeding on their larvae.
