Description: Rineloricaria daraha is distinguished from all its congeners by having seven branched pectoral-fin rays (vs. six), long digitiform papillae on the ventral surface of the lower lip (vs. button-like papillae) and by the presence of a large and multi-angular preanal plate limited anteriorly by four or more variably sized plates much smaller than the preanal plate (vs. a quadrangular preanal plate surrounded by three to five polygonal plates slightly smaller than the preanal plate). Reproduction: The Rineloricaria species are usually cave spawners, where the female will place their eggs after the male has cleaned inside. The male will then guard and fan the eggs until hatching. The eggs will hatch in 4-5 days whereas the male can now be removed. More breeding information can be found here in the articles breeding section. Aquarium Care: Not an easy species to keep with excessive demands on good water quality. Prefers water movement in the aquarium. Diet: Omnivore. Vegetable food such as cucumber and other various foods such as tablet, flake and frozen. Etymology: The genus name Rineloricaria: meaning rine-rasp, referring to sharp bristles on sides of snout (of males); Loricaria, genus in which type species, R. lima, had originally been described. The specific name of daraha. A local spelling of Rio Daraá, Amazonas, Brazil, type locality. Remarks: The planned construction of a hydroelectric plant in São Gabriel da Cachoeira, on the Rio Negro, poses a threat to the species, which could cause changes to the environment in part of its distribution area. However, it is suspected that the possible population decline resulting from these changes does not represent a threat to Rineloricaria daraha , due to its wide distribution in the basin (Least Concern IUCN 2022).
