The Sundadanionidae are a family of very small freshwater fish from the order of the carp-like consisting of nine species in two genera . Species of the Sundadanionidae occur in tropical Southeast Asia on Borneo , Sumatra , Bangka , Bintan and Singkep and inhabit peaty swamps and black water rivers .
features
For the family there is currently no description of the diagnostic, apomorphic morphological characteristics, since the relationship of the two fish genus belonging to the family is justified by molecular biological investigations. All nine fish species currently belonging to the Sundadanionidae are very small, 1.6 to 2.3 long carp fish relatives, which have an elongated body, slightly oval in cross-section and are transparent, light yellow, bluish to slightly reddish in color.
- Fin formula : dorsal ii-iii / 5-6 / i; Anal iii / 6-7; Pectorals 9-10; Ventral 6-7; Caudal 10 + 9 main rays.

Systematics
The genus Sundadanio was introduced in 1999 by the Swiss ichthyologist Maurice Kottelat and his German colleague Kai-Erik Witte together with Trigonostigma . In 2011 the former, together with two colleagues, described Fangfangia spinicleithralis , the only species of the genus Fangfangia that is monotypical . Both species of fish were initially placed in the subfamily of the Bärblinge within the carp fish (Cyprinidae). The Sundadanionidae family was in 2010 by the British ichthyologist Richard Mayden and his Chinese colleague Wei-Jen Chen for sundadanio introduced. At the beginning of 2018 a comprehensive revision of the systematics of carp-like (Cypriniformes) was published in which, in addition to Sundadanio , Fangfangia was also placed in the Sundadanionidae family.
