This potentially-undescribed species first became available in 2002, and males and females were marketed as 'Danio sp. hikari yellow' and 'D. sp. hikari blue', respectively. Subsequent DNA testing in the United States revealed them to be the same species and genetically distinct from the very similar B. kerri. It can be told apart as the central body (P) stripe always extends into the caudal fin whereas in B. kerri it terminates at the caudal peduncle. Only a single population of B. kerri was sampled in the stu...

This species is quite uncommon in the aquarium hobby although its name is sometimes used in reference to the similar-looking, apparently undescribed congener S. cf. balteata, and both are also traded as 'sumo loach', 'tri-banded sumo loach', and 'orange saddle-back loach'. Following Kottelat (1990) it's diagnosed by the following combination of characters: unique colour pattern consisting of two da...

It also possesses 33-34 lateral line scales and a series of dark spots at the base of the dorsal-fin rays, and lacks scales on the lower portion of the body and abdomen. The genus Garra is a particularly enigmatic grouping with new taxa...
