[Ebook] 500 freshwater aquarium fish – Chinese Algae Eater (Gyrinocheilus aymonieri)
Both the common names for this species are misnomers, since this fish is not a “true” loach—as in the barbel-bearing Balitoridae and Cobitidae — and it does not occur in China. It does, however, eat algae and is able to attach itself to the substratum with its suckerlike mouth. It also has special adaptations, such as an aperture in the top corner of the gill cover that allows it to take in water for respiratory purposes while still clinging onto a surface with its mouth. A golden form of this species is now widely available.
