Description: Placed in the Hypostoumus cochliodon species group which have a shorter body and more high backed than other members of the Hypostomus. They have a small number of spatulate teeth with a single cusp with the jaws arranged in a V shape.The Hypostomus genus has 7 rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 dorsal fin rays. Hypostomus pyrineusi is distinguished from most members of the H. cochliodon group except some H. cochliodon, H. levis, H. ericius, H. oculeus, and H. taphorni by having 0 - 10 (usually 0; Fig. 2 B) odontodes on the opercle (vs. 11 or more). Hypostomus pyrineusi further differs from H. hemicochliodon and H. sculpodon by lacking a ridge on the pterotic-supracleithrum, by the presence of large, spoonshaped teeth (vs. teeth intermediate; Fig. 1 C vs. B), and a lack of a buccal papilla; from H. ericius, H. hemicochliodon, H. oculeus, and H. sculpodon by lacking strong, sharp keels on the lateral plates; from H. levis by having an adipose fin; from H. cochliodon by having the spots more numerous and close-set on the body (vs. spots absent or widely spaced); and from H. taphorni by having pigmentation on the lobes of the caudal fin equally distributed (vs. lower lobe darker than upper) - Armbruster (2003). Aquarium Care: As with most of this genus, will do well in a larger aquarium of 120cm (4ft) or over with the aquarium well filtered. Water parameters can be quite diverse for this genera. Peaceful species that will dig up plants with their constant burrowing in the substrate so better to put plants in pots. Diet: Omnivore with a liking for green, tablet and frozen foods. This species is also a lover of wood which should be provided for in the aquarium.
