Family: Balitoridae
Pseudogastromyzon fangi — a Balitoridae from southern Chinese mountain streams, peaceful grazer; squabbles are brief pushes. Reaches 4.5–6.6 cm; loosely social; crowding causes endless pushing. 20–26 °C.
A Balitoridae species native to southern Chinese mountain streams: Pseudogastromyzon fangi lives bottom-dwelling on rock surfaces over fast-flowing mountain streams, clinging to rocks. Peaceful grazer; squabbles are brief pushes. Adults reach 4.5–6.6 cm. It is one of the aquarium-kept Pseudogastromyzon species we profile, alongside Pseudogastromyzon cheni, Pseudogastromyzon fasciatus, Pseudogastromyzon myersi.
A moderate-level species: peaceful grazer; squabbles are brief pushes; stable water matters more than fancy equipment.
Hold 20–26 °C and keep it stable — 20.0–26 °C typical for the genus. Cool, highly oxygenated water.
Expect 4.5–6.6 cm as an adult, living bottom-dwelling on rock surfaces. A 52 L tank or larger gives it room.
Algae and biofilm specialist; supplement with wafers. Feed two small meals a day rather than one large one.
Peaceful grazer; squabbles are brief pushes; loosely social; crowding causes endless pushing. Good company: Other cool-water stream fish — Share the need for oxygen and flow. Keep away from Large aggressive cichlids — Disrupt the calm grazing regime.
Its home waters are southern Chinese mountain streams — fast-flowing mountain streams, clinging to rocks, with very strong, highly oxygenated current.
In the aquarium: breeding rarely reported in aquaria; presumed egg-scatterer. Difficult to distinguish.
