Relevant Information:

We review the complex history of those species included in the Hypostomus emarginatus species complex and recognise them in Isorineloricaria and Aphanotorulus. Isorineloricaria consists of four valid species: I. acuarius n. sp., I. spinosissima, I. tenuicauda, and I. villarsi (Ray & Armbruster 2016). Description: Isorineloricaria tenuicauda can be diagnosed from from I. acuarius by having a smaller caudal peduncle width to pectoral spine length ratio (31.5–56.2% vs. 59.6–65.2%), which separates 95% of individuals; from I. spinosissima by having a larger caudal fin depth to head length ratio (see diagnosis of I. spinosissima); and from I. villarsi, by a rounded ridge present on the compound pterotics (vs. sharp ridge). Isorineloricaria tenuicauda can be further diagnosed from Aphanotorulus ammophilus and A. unicolor by a single, large buccal papillae (vs. multiple buccal papillae); and from A. emarginatus and A. horriddus by having rounded ridges on the compound pterotics (vs flat compound pterotics) (Ray & Armbruster 2016). Aquarium Care: Non territorial and peaceful but they are messy eaters and as such good water quality would need to be adhered to. A large tank over 5ft (150cm) would be needed due to the eventual adult size of this catfish. Diet: Omnivore in the aquarium but prefers vegetable foods. Remarks: Found on some online sources as Squaliforma tenuicauda but listed as the current status of Isorineloricaria tenuicauda in Eschmeyer's Catalog of Fishes.
