A week ago another one of my goldfish got stuck. This time in between the float valve and side of the pond. When I freed her she was injured, fell on her side. I thought she was dying. Then the most remarkable thing happened that I could ever see in a fish pond. Two of the other goldfish went one on either side of her and forced her up right! Then the three traveled around the pond at top speed. When they left her alone she flopped on her side, and then this started again forcing her to breathe. This went on for six hours. After this time they stopped and she stayed right side up by herself. She did not eat for several days and stayed far far away from me. Now the water is getting cooler and she is first in line to get fed. It seems that these devices I use to keep them safe like pipes and float valves can turn out to be death traps. RDK
