Etymology: Nandus: 'Nandus' is a Bengali local name, but it lacks a proper reference; ‘nanda’ is a Bengali fish name but probably for a different species (J. Müller, pers. comm., April 2021, after information from native speakers); andrewi: Named for Andrew Arunava Rao in recognition of his discovery of this new species and assistance during field work in India.
Eponymy: Andrew Arunava Rao is an ornamental-fish collector and breeder who owns and runs ‘Malabar Tropicals’. [...] (Ref. 128868), visit book page.
