Due to the recent paper (2018) by Lujan et al. this
is a new described genera. They erected the new genus
Avalithoxus for Lithoxus jantjae,
a species that is narrowly endemic to the Ventuari
River immediately upstream of Salto Tencua and is
unique in Hypostominae for having only 12 branched
caudal-fin rays. Lithoxus is restricted to
the Essequibo and Correntyne rivers in Guyana and
Suriname. Aquarium Care: Quite a
demanding genera which need pure, oxygen rich water.
They need plenty of hiding places and the aquarium
to be very strongly filtered. Diet:
Insectivores that feed in their natural habitat from
insect larvae on rocks. Feed Frozen mosquito larvae,
brine shrimp and Daphnia. They will also
except tablet foods.
Known only from ~180 m a.s.l. in the Ventuari River,
immediately upstream of Salto Tencua in the central
region of Amazonas State, Venezuela.
