Im getting a 20" Black Arowana. I have never moved such a big fish before so i got a little worried about how i should go at picking it up The biggest "moving box" I have is a square plastic container with a lid thats 20x14x16" (lengthxwidthxheight) Do you think it would freak out or should it be ok for the 20min drive? Also, since its a beautiful & rare fish out here i would like to get it out of the tank with the least chance of damaging fins and scales. Would a pillow case or a plastic bag treat it better than a large net ? All advice welcome, Thanks!
