Betta rubra
Perugia, 1893
Max length42mm SL1.7in SLTank45 × 30cm18 × 12inTemp22–27°C72–81°FpH5.0–6.5This species was previously included in the Betta foerschi group of closely-related species within the genus, but following its redescription in 2012 now lends its name to the B. rubra group. It was first placed into its own species group by Witte and Schmidt (1992), primarily on the basis of a triangular marking that appears below the eyes of the fish, although Tan and Ng (2005) suggested that this feature is insufficient to warrant the fo...
Opsarius ornatus
Sauvage, 1883
Max length110mm SL4in SLTank150 × 60cm60 × 24inTemp18–26°C64–79°FpH6.0–8.0Type locality is 'Mé-Nam River, Thailand', with 'Mé-Nam' having been considered an older name for the Chao Phraya river in central and western Thailand prior to this species' redescription by Tejavej (2012). In fact 'menam' is the Thai word for 'river' and thus could refer to any drainage, and B. ornatus is restricted to...
Rasbora dusonensis
Bleeker, 1850
Max length162mm SL6in SLTank120 × 30cm48 × 12inTemp20–26°C68–79°FpH4.0–7.5The identity of this species was unclear for a number of decades prior to its redescription by Ng and Kottelat (2013). The confusion originated with Brittan (1954) who misidentified specimens of R. tornieri as R. dusonensis and was exacerbated by Alfred (1963) who concluded that the holotype of R. dusonensis was conspecific with R. myersi.
