Description: 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 Lithoxus lithoides from 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.
