Pethia reval, the red-finned barb, or redfin two-banded carplet, is a species of cyprinid fish endemic to Sri Lanka. This species can reach a length of 3.4 centimetres (1.3 in) SL. Congener, Pethia cumingii, also a Sri Lankan endemic, has long been presumed to be dichromatic with some populations exhibiting yellow fins and others displaying red fins. In 2008, the red-finned populations were elevated to the status of species and given the name, Pethia reval, while the yellow-finned form remains P. cumingii.
