Description
editPetrocephalus valentini is distinguished by its unique combination of morphological features. It has a dorsal fin with 19–24 branched rays and an anal fin with 24–26 branched rays. The fish has a large eye, with the ratio of head length to eye diameter ranging between 2.9 and 3.2. The mouth is very small, with the ratio of head length to mouth width between 4.7 and 5.8. Additionally, it has 12 teeth or fewer in the upper jaw and 17 teeth or fewer in the lower jaw. The pigmentation pattern includes subtle marks: a pale dorsal black mark on each side of the body below the anterior base of the dorsal fin, and an ovoid mark at the base of the caudal fin.[2]
Size
editThis species reaches a length of 7.7 cm (3.0 in).[2]
Habitat
editPetrocephalus valentini is found in the Congo River basin, specifically in the Likouala River in the Republic of Congo and the vicinity of the Pool Malebo in the Lower Congo River. It inhabits freshwater environments and is benthopelagic, meaning it lives near the bottom of the water body.[2]
Discovery
editThe species was named in honor of Valentin Mbossi, a dedicated worker at Odzala National Park. The name "valentini" was chosen to reflect appreciation for his contributions and to avoid confusion with a similarly named species, Petrocephalus mbossou.[3]
Aquarium care
editWhile Petrocephalus valentini is not commonly kept in aquariums, it would require similar care to other species in the Mormyridae family. This would include maintaining a tropical freshwater environment with appropriate water parameters, providing hiding spots and a substrate that mimics its natural habitat, and offering a varied diet.[2]
Conservation status
editPetrocephalus valentini has not been evaluated by the IUCN Red List, and there is no specific conservation status assigned to this species.[citation needed]
