Relevant Information:

This species is still listed in Fishbase and the Catalog of Fishes as Rineloricaria formosa but the name is currently accepted in some quarters as Hemiloricaria formosa. Issbrücker (Issbrücker in Issbrücker et al, 2001) declared the synonymity of Rineloricaria and Hemiloricaria as no longer valid, and the latter again as an independent genus. The differences between the two genera are based on the positions of the males bristles and the top caudal filament on adult Hemiloricaria which is absent on Rinelolricaria. 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. Remarks: This species is closely related to H. morrowi (remains smaller and does not have a dorsal spot) and H. melini (different colouration). These two species are slender and elongated.
