I have a silver angel with a body a little bigger than a silver dollar. Yesterday AM when I turned on the lights I found it nose down in one of those prearranged artificial plants with a stone base. Definitely looked dead and not moving. I had to pack lunch and get husband off to work and so it was about an hour before I got back to netting my dead fish out. Turned out he wasn't dead at all, but rather stuck. I have no idea how long he was there and of course, I thought maybe he was sick or weak, but he stayed upright and as soon as I fed the tank he was right there gobbling food. It was strange - for the rest of the day he seemed to be watching me while I was at my computer thanking me for saving his life! Probably my imagination but I am feeling some bonding! lol
