Hognose Catfish
Hognose Catfish(Corydoras multiradiatus) is a large, impressive member of the Corydoras family — previously classified asBrochis multiradiatusbeforeBrochiswas synonymised intoCorydorasin 2016. The common name comes from the distinctly upturned, pig-like snout profile that is quite different from standard Corydoras. The body is a rich iridescent green-bronze, and the high dorsal fin with numerous rays gives it a more ‘sail-like’ profile than typical corys.
Feeding & Care Tip:Hikari Sinking WafersandSera Vipachips Tropical Wafersmake excellent staples — place them near the fish’s preferred resting areas. Supplement withHikari Frozen or Freeze-Dried BloodwormsandHikari Frozen or Freeze-Dried Brine Shrimp2–3 times per week.
Native to the upper Amazon basin in Ecuador and Peru — slow to moderately flowing rivers and streams with sandy or muddy substrate. The upturned snout is an adaptation for sifting through substrate and picking invertebrates from mud — it roots through the bottom in a characteristically pig-like manner. Fine, soft substrate is important to protect the sensitive barbels.
Keep in groups of at least four — like all Corydoras, this species is more active and confident in numbers. The Hognose Cory is compatible with a wide range of community fish, including Corydoras of other species. Its larger size means it can be kept alongside medium-sized fish that would be too large for nano corys.
Formerly Brochis multiradiatus — the 2016 reclassification moved all Brochis species into Corydoras. The Hognose is the largest of the former Brochis group and one of the most impressive Corydoras relatives available, combining the peaceful, community-friendly nature of the family with a size and presence that commands attention.
