The Hypostomus genus
has 7 rays to the dorsal fin whereas the similar looking
Pterygoplichthys species have 10 dorsal fin
rays. Placed in the Hypostoumus cochliodon
species group which have a shorter body and more high
backed than other members of the Hypostomus.
They have a small number of spatulate teeth with a
single cusp with the jaws arranged in a V shape. Similar
the Paraguay and middle Paraná River basins
in Argentina, Brazil and Paraguay. A very nicely marked
species. Sexual Differences: Males
grow larger and sport longer fins. Aquarium
Care: Adults are rather intolerent towards
other large Loricariid catfishes. Wil give out a lot
of waste in the aquarium so frequent water changes
are a must. Fairly easy to keep in a larger tank over
4ft (120cm). Diet: Wood eaters so
would need soft wood in the aquarium. Food tablets,
pellets and vegeatable foods are also taken along
with insect larvae.
