The raccoons may be a bigger problem than I thought. Last night I was feeding the fishies around 4 am and suddenly there was a young raccoon in the water. I yelped and demanded No, no! What do you think you are doing? He turned around and went out the same way he got in. In a moment there were three of them attempting to get in the water and retreating when I said no but they kept on trying. Remember this is only about 10 feet from me. For the next 15 or 20 minutes they persisted. They showed no fear of me at all!! At one point, I had a raccoon between my legs trying to climb into the bucket of fish food. He even used my leg as a ladder! I had to pick up the bucket to stop that. They chased the glass floats I have in the water and lifted them out. They didn't show any interest in the fish but almost pulled over a big teracotta pot trying to get out of the water. The fish didn't seem too upset. Some of them went deeper but that was all. These babies are obviously too unafraid of people. I can redesign the plantings and probably the sides but I really worry about that lack of fear. It was certainly nothing I did that made them leave.They just lost interest. I am worried about what will happen in the future when they are hungry and I'm not around. Augggghhh!!
