Red Tail Rasbora

Red tail Rasbora borapetensis is rarely found in southern Thailand, and in the area between the districts of Surat Thani and Yala there seems to be a distribution gap. Only in the province of Yala does it become common again. Rasbora borapetensis is almost omnipresent in the lowlands of Malaysia’s east coast. The species probably populated the vast plains of the Gulf of Thailand and the South China Sea at a time when these seas did not yet cover the landscape. In my opinion, R. borapetensis wandered through this central point via the river systems of the Mekong and Chao Praya, north toward Thailand. Currently, there is a northern and a southern contiguous habitat.
