Abstract

Owing to the spectacular colouration, fish species of the genus Rasboroides have a substantial economic value in the aquarium trade of the world. All the species of Rasboroides categorized as threatened fishes. The studies revealed that some species of the genus Rasboroides are having a stable population in the South-western wet zone of Sri Lanka. Osteology of these important species was studied and the findings further support the recently described or re-described species within the genus. One of the important characters of the genus is danionin notch which was only observed in R. pallidus. This character is always observed in related Cyprinid genera Devario. The presence of danionin notch in R. pallidus is mystifying since it is independently found in two different tribes of subfamily Danioninae. Further studies ought to reveal the status of this character within the Danioninae.
