Remarks: Panda Hoplisoma are a small, Peruvian native that inhabit small streams and tributaries fed by the cool meltwater flowing down from the Andes Mountains. They can be found in both tannin-stained blackwater but also in spots where the water is clear with both having fairly cool water that can drop as low as 66°F. Wild specimens are intolerant of water that isn't cool, soft, and acidic but due to the panda Hoplisoma's popularity and ease of breeding, almost all specimens in the hobby are captive bred and much hardier than their wild counter parts. That being said, they tend to fall ill if kept in temperatures higher than 78°F for extended periods of time. It is easy to see why this little catfish became so popular in the hobby with their small size and markings that resemble that of a panda with a black mask, dorsal fin, and large spot at the base of their caudal fin.    Panda Hoplisoma were previously classified as Corydoras panda, but were reclassified as Hoplisoma panda upon publication of a phylogenomic analysis in 2024 that reclassified many species in the Corydoradinae subfamily.   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.
