he Hypostomus genus has 7 soft rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 soft dorsal fin rays. Hypostomus cordovae was a valid species according to Eschmeyer et al. (2018). Within the last decade it has also been considered by some to be a synonym of H. paranensis (Ferraris 2007, Martins et al. 2014 in Eschmeyer et al. 2018). Eschmeyer et al. (2018), considers H. paranensis to be a separate (and also valid) species from H. cordovae. Some databases still follow the synonymy (i.e. Froese and Pauly 2018) so the information provided here apply's to H. paranensis and not to H. cordovae. As of 2020 Eschmeyer et al. in the Catalog of Fishes puts H. cordovae in the synonymy of H. paranensis. 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, paranensis, is an adjective in reference to the occurrence of the species in the upper Rio Paraná basin. Remarks: This species is listed as a synonym of Hypostomus paranensis in Ferraris, C.J. Jr., 2007 and also the online reference tool Eschmeyer's Catalog of Fishes. Fishbase excepts this species but with an add-on highlighting this problem.
