Relevant Information:

First introduced in the DATZ magazine of March 1990 and given the L-number of 60. The Hypostomus genus has 7 soft rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 soft dorsal fin rays. Habitat: Rheophilic species, inhabiting largest part of freshwaters, from headwaters to upstream of the lower falls, with rocky substrate consisting of boulders, stones, gravels, and sand; the exposed wet rocks are also often covered by the Podostemaceae Mourera fluviatilis and Apinagia richardiana. Aquarium Care: As with most of this genus, will do well in a larger aquarium, with the aquarium well filtered. Water parameters can be quite diverse for this genera. Diet: Omnivore with a liking for green, tablet and frozen foods. Etymology: The specific name nematopterus: nêmatos, threaded; pterus, from pterón, fin, referring to its filamentous dorsal fin. Remarks: The size of this species is listed in Seidel, I, 2008 as 20cm (8ins) but in Fishbase as 10.7cm. We have taken on the larger size of 20cm.

IUCN Red List

This species is only known from three localities in the Oyapock river. It has a restricted distribution with an extent of occurrence (EOO) of 3,675 km2. There are two locations based on the impacts of deforestation and these are leading to a continuing decline in habitat. Therefore, this species is assessed as Endangered (IUCN 2023).
