The spotted betta or Java fighting fish (Betta picta) is a species of gourami endemic to Indonesia where it inhabits relatively cool, 22‒25 °C (72‒75 °F), highland streams of Java and Sumatra.In 1967, D. S. Johnson reported the species to be common in blackwaters of southern Malaya. Of largely unremarkable Betta appearance, B. picta attains an overall length of 6 cm (2.4 in).It is noted for the pale bars on the male's back, absent in other similar Betta species.
