Whitespot

The whitespot or blue panchax, Aplocheilus panchax, is a common freshwater fish found in a large variety of habitats due to its high adaptability. A native fish of Southeast Asia, it has even been discovered in two hot springs in Singapore.

Identified by a white-coloured spot on its head which gave it its name, the 8 cm long species tends to keep to the surface of the water, and is useful in controlling the mosquito population by feeding on its larvae.
