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
Hypostomus cordovae, Plecostomus
Paraná River system.
