What are your opinions on this? Have you ever done it? Is it recommended? These questions have come from something on ebay which caught my attention as redtail cats & arowana are in america, and they are available for 1 day shipping..
How do you think we get all these cool wildcaught fish other countries? Most of them last days in the bag. So yes, live fish get shipped ALL the time, and that's how most of us buy fish from vendors/importers. If you want something that's hard to find, getting it shipped in is your only option. You can get them shipped overnight using UPS or Fedex, or some even ship airport-to-airport where you get the fish the same day within a few hours and you pick it up at the airport yourself.
