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. This betta spawns readily and prolifically in captivity, producing easily raised fry.
Even though it is easily kept and bred, it is not one of the more popular ''Betta'' species among hobbyists, likely because, in the words of one ''B. picta'' keeper, "many just can not get excited by watching a drab colored fish that spends most of its time hiding away under the rocks and behind the plants."
Originally described by Valenciennes and assigned to genus ''
Panchax'' (as ''P. pictum''). It was found that Bleeker's ''Betta trifasciata'', described in 1850 and used as the type species of his genus ''Betta'', was identical to ''P. pictum''. As the original
type specimens are now lost,
