I have a pond in the back that I have neglected for too long. I have removed 20 pounds worth of Parrot Feathers. Some goldfish of mine had not been seen for a month. I know they are dead and I checked after plant removal. No remains of them have been found. Even checked everywhere no remains of any kind not even bone... I wonder what happened. My goosehead and crown pearlscale gone.. Nothing to bury under the date tree. It is my fault for their deaths but I just wondered what happened. Even before the overplanting, I couldn't find one of my Dojos. Do fish decompose that fast?
