Thanks so much for giving this a look- I'm a Cory catfish biologist (for real)! I study social behavior and communication. I moved to Maryland a few months ago to start a new research project, and after a long period of COVID-related administrative delays, am setting up my laboratory and am looking for a good source of ideally wild-caught (or descended from a known population- a couple or even a few generations out from wild caught would still be great, so long as the population/locality of origin are known) Corydoras aeneus and Corydoras elegans (I'll be working on an additional species, but still mulling over which one). My research is strictly behavioral, and no fish are harmed at any point (the fish from my PhD were adopted by my old lab-mates and are living in high style). I will be looking to rehome most of these fish (some I may adopt myself, I'm a bit of a Corydoras softie) after my research project has ended, and would be happy to return them to the source after the research has included (I will still of course pay full freight for them at the outset and return them with the sole expectation that will be provided or found a good home). If you or anyone you know could help, I would be very grateful!
