Relevant Information:

Eight species of Hypostomus are known from the rio São Francisco basin and could possibly occur in rivers draining into northeastern Brazilian coastal drainages. These are H. alatus Castelnau, 1855, H. francisci (Lütken, 1874), H. garmani (Regan, 1904), H. johnii (Steindachner, 1877), H. lima (Lütken, 1874), H. macrops (Eigenmann & Eigenmann, 1888), H. subcarinatus Castelnau, 1855, and H. vaillanti (Steindachner, 1877). Most of those species were originally described from the rio das Velhas, a tributary to the upper rio São Francisco, but they were not recorded in coastal drainages of the Bahia State. In fact, a detailed comparative study is necessary to establish exactly which of these species occurs in the portion of the rio São Francisco draining Bahia. In addition to the aforementioned species, only H. scabriceps (Eigenmann & Eigenmann, 1888) is known to occur in nearby coastal drainages (rio São Mateus, Espírito Santo State), (Zanata et.al 2013). The Hypostomus genus has 7 rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 dorsal fin rays. Aquarium Care: As with most of this genus, will do well in a larger aquarium, although this is one of the smaller species in the genera, and the aquarium well filtered. Water parameters can be quite diverse for this genera. Diet: Omnivore with a liking for green, tablet and frozen foods.
