What do you guys see in your ponds (weeds or not and results - saucers or streamline or both) ?
The fatter my BG are, the more they look like saucers. Skinnier BG (which tend to be shorter also in my pond) are more streamlined.
I have always thought it was a function of how much they were getting to eat - fat, fast growers are saucers.
P.S. To reiterate, pond is almost weedless.
