This is the best method if you can. Don't forget the spare batteries for the pump plus take some water in a sealed container to freshen up if needed, it should go without saying but any ray that is shipped regardless of size needs to do so on an empty stomach, this means no food 3 days before the shipping date, rays that arrive in putrid water are either DOA or very close to it, this could mean the chances of it surviving are no better than 50\50.
