Relevant Information:

Similar to Hoplisoma schwartzi but this species does not posses the orange blotch in the predorsal region and the first ray of the dorsal is transparent or greyish black whereas H. parallelum has the first ray of the dorsal black. This species was first given the C-Number of C002. A very beautiful species. Lineage: Placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. A revision in the future would constitute the resurrection of the genus name Hoplisoma (Agassiz, 1846). As of the latest revision (Dias et al 2024) Corydoras parallelus has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to parallelum. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium tank mates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Diet: A good quality flake food and tablet food for adults with sporadic feedings of frozen or live food will keep your Corydoras in good health. Remarks: The thumbnail images 5 & 6 are of specimens which reportedly grow bigger than H. parallelum and has two thicker stripes, which have in the past been exported to Japan as "Super parallelus". It is reported that this parallelum look-a-like is sympatric with Brochis bifasciatus (info. from K.C. Cheung). There is another parallelum look-a-like species which has a longer snout which may in time be given a new CW number (from Ian Fullers website at www.corydorasworld.com). Still found on some online sources as Corydoras parallelus.
