ok, so some of you I am sure have delt with shipping fish before(meaning you ship them to someone else) I have never done it before, but am selling some fish and have a question, about how much water and what size bag would you use to ship a foot long pleco and a 6-7inch silver dollar? my guess was about 1.5-2 gallons for the two. I want them to arrive safely should they need to be shipped(someone showed interest in those two), but I also want to make the shipping costs as minimal as possible for the buyer as well. Any suggestions? what do you home aquarists do to prep your fish for shipping? I know pros use certain additives and pure oxygen in the bags, but I don't know where to get my hands on that stuff, or even if its all necessary for an over night shipment.
