Steve Grant is a UK aquarist and amateur ichthyologist who specialises in catfish and loaches. Steve has collected (and eaten) catfishes in Peru and Bolivia. This allowed him to see first-hand the biotopes that they live in, and what other species they can be found with.

He has authored numerous articles for aquarium magazines and the Catfish Study Group Journal, of which he is now the Editor; as well as the book ‘Pims’, which covers the Pimelodoidea, and his latest book on Banjos, Dorads and Woodcats. He is a speaker at catfish conventions.

Steve has described three species of Corydoras, and now has a Corydoras named after him. He has described a genus of loach; three genera of driftwood catfishes, an Asian catfish species, and codified an L number pleco. He has also rediscovered the lost type specimens of numerous catfish species; as well as writing about the identify of old and forgotten scientific names. He runs the Facebook group Catfishes of the World, which is an online place for aquarists and ichthyologists
