I was wondering if any of you have problems with any of your fish disappearing? I have had a big one and must recently one of my shubunkins disappear from my pond. I have recently bought a net to put over it which takes away from the beauty of my pond. Any suggestions on what I should do? Here are some pictures before the netting I so miss. The last one is with the net..I really hate it, but I don't want my fish being dinner for any predators.
