Starts to look really pale, and not just at the growing tips. The color when this happens is inconsistent across the 'blades'. Almost looks like it's 'cracking'. ....not sure I helped too much. Anybody with a photo? FWIW, I've never seen it to be a big deal when it dies. Makes the tank surprisingly cloudy, but doesn't seem to case big problems. Anyone else ever have a Cauerpa melt down kill other stuff?
