Bill when I had my last winter kill BG, PS, RE, CC, LMB were wiped out except for a few minnows and one GC that I still have. With that wipe out I decided to change my pond with just minnows and I add 6 GC to my one surviving one. I suspect you think I may be confusing the PS with BG but the PS are so much more colorful that it would be hard to do.
