Relevant Information:

Description: Hypostomus subcarinatus is distinguished from all congeners by having a blue-tan dorsal fin in living specimens (vs. not having a blue-tan dorsal fin). Additionally, H. subcarinatus is diagnosed from the species of the H. cochliodon group by having slender viliform bicuspid teeth (vs. robust spoon-shaped teeth) and by having dentaries angled to each other more than 90 degrees (vs. dentaries angled from 80 to 90 degrees); from the remaining congeners except H. affinis, H. ancistroides, H. argus, H. aspilogaster, H. borellii, H. boulengeri, H. carinatus, H. careopinnatus, H. commersoni, H. corantijni, H. crassicauda, H. delimai, H. dlouhyi, H. faveolus, H. formosae, H. gymnorhynchus, H. hemiurus, H. hoplonites, H. interruptus, H. micromaculatus, H. niceforoi, H. nigrolineatus, H. pantherinus, H. paucimaculatus, H. piratatu, H. plecostomus, H. punctatus, H. pusarum, H. rhantos, H. scabriceps, H. seminudus, H. tapijara, H. velhochico and H. watwata, by having moderate keels along the five lateral series of plates (vs. lacking keels); from the species above by having a more slender and elongate body, what can be somewhat depicted by the anal-fin unbranched ray length longer than head depth (vs. anal-fin unbranched ray length shorter than head depth) (Zawadzki CH, et al 2019). Aquarium Care: Will need a good sized aquarium of 5ft (150cm.) or over due to their final adult size. As this genus in the main are messy eaters, good water quality and filtration would need to be adhered to. Diet: Will eat all manner of foods in the aquarium, vegetable, tablet, pellet foods and a good quality flake food. Etymology: The specific name subcarinatus: sub– (L.), less than or somewhat; carinatus (L.), keeled, i.e., slightly keeled, presumably referring to four longitudinal ridges on sides.

IUCN Red List

Hypostomus subcarinatus is recorded in coastal drainages of eastern Brazil, with the possibility of occurrence in the São Francisco basin being uncertain; however, it presents taxonomic problems. Because it is very similar to other species of the genus Hypostomus , taxonomic identification is difficult, which can lead to uncertainties in collection records. For this reason, there is no reliable information on the distribution, abundance, and threats to which the species is subjected, making its assessment impossible. Therefore, Hypostomus subcarinatus was categorised as Data Deficient (DD), (IUCN 2022).
