Ladiges, 1975
Max length60mm SL2.4in SLTank45 × 30cm18 × 12inTemp20–28°C68–82°FpH5.0–7.5The crescent betta, Betta imbellis, is a labyrinth fish thought to be native to southern Thailand, Peninsular Malaysia and northern Sumatra. It has been line-bred for aggression in southern Thailand and hybridised with B. splendens and other congeners for the ornamental trade, producing colour forms that do not occur naturally. Introduced ornamental forms and other Betta spp. are having an adverse effect on the genetic integrity of some wild populations.

Max length33mm SL1.3in SLTank45 × 30cm18 × 12inTemp22–28°C72–82°FpH5.5–7.5Betta siamorientalis is a small bubble-nesting labyrinth fish from eastern Thailand, western Cambodia and Vietnam. It lives among submerged vegetation in marshes, flooded fields and rice paddies. Before its description in 2012 it was considered a colour form of B. imbellis known as 'black imbellis', and it has also been confused with B. splendens, but DNA analysis showed it to be distinct. Males have a dark brown to black body and a black opercle with two reddish vertical bars.
