Remarks: Hog nose Brochis have had a lot of changes in regards to taxonomy over the years. When they were first described in 1960, they were classified as Chaenothorax multiradiatus, but were subsequently reclassified as Brochis multiradiatus. Then, in 2003, Brochis was considered synonymous with Corydoras so once again the fish was reclassified, this time as Corydoras multiradiatus. Finally, they were reclassified back to Brochis multiradiatus upon publication of a phylogenomic analysis in 2024 that reclassified many species in the Corydoradinae subfamily.  

  As they grow, hog nose Brochis change from a tan and black spotted juvenile pattern to a shimmering green-bronze color. They look very similar to the emerald green Brochis (Brochis splendens) with the main difference between the two being that the hog nose Brochis has a longer snout and more dorsal fin rays. They are one of the largest species of Corydoradinae so they look excellent in a large tank with big cichlids such as Geophagus, Heros, and other South Americans.

  Corydoradinae are small, peaceful catfish that are active shoalers and will stay near conspecifics, making for a lovely sight. They feed by searching through sand with their barbels, making such a substrate necessary for their long-term health. Gravel substrates tend to be abrasive and damage the barbels, leading to infections and an inability to find food.

  While these friendly catfish are willing to swim with other species of Corydoradinae different from their own, this does not provide the same social need as being kept with members of their own species. Because of this, it is highly recommended to keep at least six of each species of Corydoradinae present in the aquarium and only mix species if one has the space to keep at least six of each.

  Corydoradinae are often looked at as "scavengers," but they should be treated in a similar fashion as the rest of your fish. They are omnivores and require a mixed diet. Sinking prepared foods are readily accepted, as are frozen and live foods such as brine shrimp, blackworms, and bloodworms.
