Brochis multiradiatus has a 17 dorsal ray count compared to B. splendens (12) and B. britskii (15) and it has also a far longer snout than the latter two. Brochis was synonymised with Corydoras by Britto in 2003 but in time there will be a revision which will resurrect Brochis (Cope, 1871) to full genera again so in the meantime we are sticking with Brochis as there is marked differences with the both genera. Brochis is included in Lineage 8 (sub-clade 1) with the "intermediate long-snouts" with deeper bodies. Aquarium Care: Best kept in water which has a pH in the range of 6.0-7.2, and hardness in the range up to 15.0 dGH. This catfish is ideally suited to temperatures in the range of 21-24ºC. I would suggest a tank of the minimum size of 30” x 15” X 12” for a shoal. The preferred substrate for keeping these catfish should be good quality aquarium sand such as BD Aquarium Sand, or very smooth rounded gravel in order to prevent their barbels from being damaged. The aquarium should provide some shelter in the form of rocks, bogwood and aquatic plants. As with all other species of fish, water quality and general husbandry is very important, and recommended would be a minimum of 25% water is changed on a fortnightly basis. Diet: As with all the other Brochis they will readily accept a mixed and varied diet, catfish pellets, good quality flake foods, granular foods, cultured whiteworm and frozen foods such as bloodworm.
