Taxonomy & naming
Poll described the species in 1959. The type locality is the rapids at Kinsuka, Regina Falls, near Kinshasa in the Democratic Republic of the Congo. Garra is a large genus of sucker-mouthed labeonine cyprinids, ranging from West Africa and the Middle East across South and Southeast Asia to China.
Morphology
A typical Garra: elongate, with a ventral mouth and an adhesive mental disc on the lower lip. FishBase gives a maximum of 4 in TL; colour has not been described in the sources the atlas uses.
Habitat
It lives in the fast rapids of the lower Congo River, a region of strong current and rock, and FishBase also reports it from Angola. FishBase gives a temperature range of 73–77 °F, a minimum pH of 6.5 and a minimum hardness of 15 dH, with no upper values.
Feeding
Garra species are grazers. The lower lip forms an adhesive mental disc, and the fish rasp algae, diatoms and biofilm from stone with the hardened jaw edge, taking small invertebrates and detritus along with it. The diet of this species has not been described separately.
Mating
Mating has not been described for this species. Related Garra are seasonal egg-scatterers with no parental care, with ripe males carrying snout tubercles.
Breeding
Spawning has not been documented. Related Garra scatter eggs over stone and gravel and give them no care.
In the aquarium
Treat it as a hillstream fish: a long tank, strong flow, high oxygen, rounded stones and wood with algae and biofilm to graze, and a tight lid, since Garra climb and jump. Keep a group rather than a single fish, and give mixed algae wafers, sinking pellets and small live or frozen foods. Congo rapids fish need very strong flow and high oxygen, and the warm 73–77 °F range suits them. Care notes come from the genus.
Conservation
The IUCN Red List category is Least Concern, assessed in 2009. Threats have not been described.
