 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.Mouthbrooders, spotted bettas spawn "en masse" when triggered by water changes; this is likely to be an adaptation to reduce the chances, by saturating the environment with young, of individual fry falling prey to predators.
