Taxonomy & naming
Pellegrin described the species in 1936 as a Discognathus, from the vicinity of Kissidougou in French Guinea. It is now placed in Garra, with the authority in parentheses. Stores list it as Garra cf. waterloti, the cf. marking that the fish sold have not been compared with the type. FishBase notes affinities with the Chad basin Garra dembeensis. 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 3 in TL; colour has not been described in the sources the atlas uses.
Habitat
The type locality is in the Guinea highlands of West Africa. FishBase gives the range as the Senegal River and the upper Niger, with records from the Benue, in freshwater of tropical conditions. Water parameters have not been published.
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 for this species. 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. Care notes come from the genus.
Conservation
The IUCN Red List category is Least Concern, assessed in 2019. Threats have not been described.
