I've actually help some LFS bag their rays since most don't get them often. One day I was at a lfs and some guy was buying a 12" Motoro...a pair of them...the guy at the store was trying to back the ray for almost 30mins...LOL...so I finally gave in and told them I've got rays and I'll help bag her!..took me less then 5 mins to bag both using the bag method....burried half the bag under the gravel and gently guilded the ray with a prong into the bag, lifted it and she's in!...got her out and place in styroform box and did the second...the buyer asked if I could go and put them into his tank at home...I said ummm...I'm busy! At least the buyer had a 220 tank for them to go into....
