Okay, so I think I stumbled onto a mildly controversial topic. Let me preface this with the concept that I apply when shipping certain species of corydoras. The black corys seem to be like several other species of cory, in that when they are stressed they release a toxin. Given that the packing/shipping is stressing in general, they end up releasing toxins in their small amount of water and end up poisoning themselves. So the method to avoid this? Stress them before packing, water change, and then pack them. So far this has worked pretty well, although I'm still leery about sending them via priority mail.
I made a video of me stressing a group prior to packing, and given that this is for entertainment purposes, I made it a bit dramatic. I normally don't go to this much effort, I just pull them from their tank, let them sit in a dip n pour, then change the water in it for fresh water after about 10 minutes, just prior to bagging.
And finally, let me once again emphasize that I really do love my fishies =]
