All of my fish except one injured one have been hiding behind the waterfall in my 900 gallon pond for three days now. The injured guy has lost some scales on his sides and is lying/swimming on his side. It may have been a raccoon, I don't know. I wonder how long the fish will hide. I assume they will want to eat again someday. I can't tell if any were taken, because I can't see down in the waterfall center, but I did see some fish in there. I hate it that they've been scared and injured.
