(snip) Do you feed these fish pellets??? If you do those GSF will continue to grow to 8" or more, maybe 10"?
A 10" GSF would be a big one, and would top some state records. The world record is about 12 inches and 2.2 pounds.
I've got a few over 8" now. Any GSF I catch that are small I cut the tail fin off and make them LMB snacks. But the ones over about 7" go back in the pond to grow. I want to see if I can get them big.
