I've always wanted an outdoor fish pond and to be honest I've never done any studies on the project. I just felt it out and oddly enough the shape just happened to turn out heart shaped. I did all the digging and landscaping by myself. Now I have hit a lot of road blocks and lost a lot of fish, but because of my will to succeed I finally am holding firm! I love my fish and ask that they be protected everyday and truely I think thats what makes a fish pond or anything else for that matter flurish!
