Gyrinocheilops pennocki Fowler, 1937 Gyrinocheilus pennocki, also known as the spotted algae eater, is a species of freshwater fish endemic to the Mekong basin in Cambodia, Vietnam, Laos, and Thailand.

[1][2][3] It grows to 28 cm (11 in) SL.

[2] It is an important species caught both in commercial and artisanal fisheries.

[1] The fish is named in honor of Charles J. Pennock (1857–1935) of Pennsylvania, an ornithologist to whom Fowler was indebted for acquiring various North American fishes.

[4] Gyrinocheilus pennocki are synonymous to Gyrinocheilus aymonieri but differ in body proportions primarily in head shape.
