Thank you all for your great knowledge. Andrew I really enjoyed you web site. I would like to plant something in the water for the fishies. Can you recommend a nice lily plant that is beautiful that fish like and WILL NOT spread like a wildflower. I am making a beach area for the pond so friends and family have a nice place to swim and soak up some rays, and I don't want to plant anything that will take over the pond. I also was wondering if planting water plants would be inviting to snakes? The pond is located pretty close to woods and I may have that problem anyway. Also, if I would go with a lily plant, is there a certain depth the water should be? Thanks to all of you for your great help.....
