Similar in colour pattern to C. paleatus and C. longipinnis but the blotches in the body are smaller and lighter in colour and is also a smaller species. Males have longer dorsal fins. First given the numbers of C007 and CW024 untill described by Tencatt et al, 2014. Among Corydoras species from the Rio Paraná basin, Corydoras diphyes and C. flaveolus are the species that exhibit the most similar colour pattern to Corydoras gryphus. However, the new species can be distinguished from both species by lacking dark spots on the head (vs. spots present on the dorsal portion of head and snout) and by having irregular and variable-in-size black blotches on midline of flank (vs.rounded blotches with similar size). Corydoras gryphus also presents pectoral and anal fins with black bars, whereas these fins are hyaline in C. diphyes (Tencatt et al, 2014). Lineage: Placed in Lineage 6 which has always been classified as Corydoras (Lacépède, 1803) so a new genus would need to be described and a new type species when a revision is carried out. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake.
