The Hypostomus genus has 7 soft rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 soft dorsal fin rays. Habitat: Hypostomus affinis is found in large and small waters, in lentic or rapid sections of the river, on rocky or sandy-rocky bottom. Young specimens inhabit the riparian vegetation along those habitats. Aquarium Care: As with most of this genus, will do well in a larger aquarium, 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. Etymology: The specific name affinis: meaning related, referring to its “remarkably close” appearance (translation) to H. commersoni.
