Description: The Hypostomus genus has 7 soft rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 soft 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. Etymology: The specific name pusarum: –arum (L.), commemorative suffix, plural: in memory of the boys who collected this catfish with their hands and with dip-nets under overhanging grassy banks at Ceará-Mirim, Rio Grande do Norte, Brazil, “the best collectors we found in Brazil” (presumably based on a native word, meaning unknown).
