Puntius lateristriga
Spanner Barb
The Spanner barb (Puntius lateristriga), or t-barb is a tropical freshwater fish belonging to the Cyprininae sub-family of the Cyprinidae family. It originates in inland waters in Asia, and is found from the Malay Peninsula to Borneo. The Spanner barb is an open water, substrate egg-scatterer, and adults do not guard the eggs. Predominantly found in forested hill streams with very clear water, often in the pools that form at the base of waterfalls. The substrate in many of these biotopes is composed of smooth, water-worn rocks and boulders of varying sizes. The combination of flowing water and rocky substrate means that the water is very well-oxygenated and sometimes quite turbulent. In some areas it also exists in lowland habitats where the rivers tend to be wider and slower-flowing and it has also been collected from blackwater streams typically associated with ancient peat swamps.
