Similar to Hoplisoma sp. (CW077), which is shipped out of Colombia, but this may be the same species, as the location in Colombia is unknown. This could indicate another catchment area in another country. Also similar to CW104 from the Rio Cuduyari in Colombia and CW108, but this species lacks the dorsal blotch (corydorasworld.com). Habitat: Hoplisoma tenharim is so far only known from the Rio Manicoré and Rio Marmelos, all draining into the Madeira basin. Lineage: Placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. Aquarium Care: A minimum-sized tank of 24” x 15” X 12” for a small shoal. Good quality aquarium sand, such as BD Aquarium Sand, or very smooth, rounded gravel, is the preferred substrate when keeping these catfish. The aquarium should provide some shelter in the form of rocks or bogwood, along with some aquatic plants. As with all other fish species, water quality and general husbandry are crucial, and it is recommended that a minimum of 25% of the water be changed on a weekly to fortnightly basis. Diet: Readily accepts a mixed and varied diet which includes granular foods, frozen bloodworm and a good quality flake. Etymology: The specific epithet “tenharim” pays tribute to the Tenharim people, an indigenous tribe native to the Madeira-Tapajós interfluve. They are known for their self-denomination as Kagwahiva, meaning “we” or “us” in the Tenharim language, as well as for their close cultural ties with the hydrographic systems in which they live. Unfortunately, since the construction of the Trans- Amazonian highway, the survival of the Tenharim people has been in jeopardy. A noun in apposition. Remarks: The Chameleon shaped eyes are a distinctive feature in this species which correlates to CW077.
