Sounds to like the bait is getting it’s due. For years anglers have used those cute little shiny goldfish as bait to catch the bigger fish. Now along comes a few folks that dumps their fish tanks to the lake, and it begins. 1 goldfish is bait, 3 goldfish is a school. 15 4lbs goldfish better make you worry. Do you have any idea how many of his relatives have been flushed down the toilet.
Just think of a 500lbs Goldfish following your 12’ aluminum boat around the lake, to the tune of Jaws.
