I just made a bait tank from a 9 gallon poly water storage tank that I got at West Marine. I have the same concern about bait going into the corners and getting injured. My solution is to cut a large diameter PVC pipe lengthwise into 90 degree segments. I am going to install the quarter-round section of pipe in each corner using 3M 5200. I'll wind up with a roughly oval shaped tank, but will not sacrifice much of the internal volume.
