Another interesting species
from the Rio Formoso is the Formoso Pleco (Hypostomus
sp. Rio Formoso). This is a large species. We observed
specimens more than 60 cm long. But smaller fish we
only found in the small rivers. (Petersen, P.). The
Hypostomus genus has 7 rays to the dorsal
fin whereas the similar looking Pterygoplichthys
species have 10 dorsal fin rays. Aquarium
Care: As with most of this genus, will do
well in a larger aquarium, with the aquarium well
filtered. Water parameters can be quite diverse for
this genera. Diet: Omnivore with
a liking for green, tablet and frozen foods.
