During summer there are hundreds of 2-3" BG that hang around my diffusers. They seem to ride the bubbles to the top and disperse outward when they reach the top. When I approach with a boat they will stop momentarily, then if I remain still they will start up again.
At times, from the bank I will see swarms of them spook in a circular pattern around the bubble column. I assume a LMB is chasing them around the bubble column.
Great looking BCP and a lot of good eating. Your pond is productive!
