I know someone who has freshwater mussels in their pond and they aren't crazy that they're there. They don't know how they got there but I see now how they could have arrived on some fish. The older mussels can be sharp on swimmers feet and they often throw them back into the deeper water. Their pond is the first I've ever heard of that had mussels. Someone told them the mussels are a sign that their pond is healthy, I've never heard that before either. Are mussels too big for redear?
