I've also seen HSB die after a fight in cool water, but much more frequently in warm water. Another interesting note is that sometimes a HSB will suffer from a cramp after a warm water fight. They will curl up and can't draw oxygen. You can salvage many of these fish if you run them through the water, face first, rapidly back and forth. The air across the gills will allow them to "uncramp". It's a Kreb's Cycle thing, I guess. :rolleyes:
