The Eastern Province rocky (Sandelia bainsii), also known as rocky kurper, is a species of fish in the family Anabantidae.

[2] The specific name of this species is thought to honour the Scottish geologist, explorer and soldier Andrew Geddes Bain (1797-1864) who also collected zoological specimens.

Bain served as a captain in the Cape Frontier Wars and may have fought the tribal chief Sandile, for whom Castelnau named the genus.

It is doubtful whether those fragmented populations will be viable in the future because they find themselves under a number of threats from agricultural practices, pollution and invasive species.

[1] It is found in the Bloukrans River in the Blaauwkrantz Nature Reserve.
