I was thinking about breeding/selling some albino corydoras again. Previously I have given them to my lfs and used either a large Tupperware container or 5 gallon bucket to transport them. This time I plan on posting them online to sell locally and was wondering the best way to give them to the people I am selling to. I know their spines can puncture bags(although the lfs sold them to me in a bag). any advice is appreciated.
