Corydoras sodalis
Mistakenly sold as C. punctatus sometimes. Aquarium Glaser writes: "The species Corydoras sodalis is quite often imported, but mostly under the completely wrong name of Corydoras punctatus. The real C. punctatus originates from Surinam, occurs hardly ever in the trade and looks very similar to the well known species C. julii and C. trilineatus. A cory that can be really easily confused with C. sodalis is C. reticulatus. Both have the same pattern and the same body shape, but in C. reticulatus always a clearly marked, dark spot is present in the dorsal fin, which always lacks in C. sodalis."
