Phoxiscus kikuchii Ōshima, 1919 Aphyocypris kikuchii is a species of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies.

[1][2] It is a benthopelagic freshwater fish that grows to 8 cm (3.1 in) total length.

[1] Aphyocypris kikuchii has a low dispersal capability, which in turn leads to reduced gene flow between populations and higher genetic differentiation.

During the past few decades, its populations have diminished immensely due to habitat degradation.

[5] It is named in honor of Yonetaro Kikuchi (1869–1921), collector for the Taipei Museum in Formosa (Taiwan), who collected the type specimen.
