BillD. I think your GC as they grow another year older, will start working more heavily next on the floating leaf pond weed. Thus next year you will see fewer floating leaves as the GC eat the vegetation before it reaches the surface. When I had eel grass and GC the GC worked heaviest on the spring eel grass that still had leaves from the prior year's plants. Keep an eye on the progress of your GC and keep us informed how they perform on your weed community.

Despite the body color variation of the one individual, I think all the BG in your picture are males. I base this on shape of the opercular flap. Color variation can be significant in BG from some ponds.
