Relevant Information:

Habitat: Currently, Paralithoxus comprises and species with a cratonic distribution restricted to the bases of the Guyana Shield (Silva et al., 2017). Ferreira (1993 ) presented the first record of Lithoxus lithoides and Paralithoxus bovalli for the River Trumpets, in Northern Brazil. As the Ireng River (called Maú River in Roraima), type locality of P . bovallii, is a tributary of the Takutu River in Brazil - Guyana border, the presence of Paralithoxus representatives in other Brazilian drainages was already expected. 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. Etymology: The specific name boujardi: In honour of Thierry Boujard (b. 1959), Laboratoire d’Hydrobiologie de Guyane (INRA), who at the time had been studying the fishes of Guyana for six years [authorial note: Muller later seen as S. Fisch-Muller]. Remarks: Still found on some online sources as Lithoxus boujardi.

IUCN Red List

Paralithoxus boujardi is endemic to French Guiana with an extent of occurrence (EOO) of 21,165 km2. Several small streams within the distribution of the species show considerable impact from gold mining, and there are six locations based on this threat, which is also inferred to be causing a continuing decline in habitat. Given the EOO is just over the Vulnerable threshold, this species is assessed as Near Threatened. It should be monitored. It is possible that the full extent of the distribution of the species has not yet been examined, and future studies should explore the distribution of the species (IUCN 2023)
