These people are nuts!
Goldfish are like most fish, in that they continue to grow for their entire lives.
We had one in a pond that was about three feet long.
If any fish harm a lake, all fish will do the same harm. Goldfish are just carp anyway.
LMAO they are getting 50 or 60 fish a year through electrifyingthem, Big Deal
These fish came from someone who got them in a bowl at a carnival and dumped them in the lake.
My Brother in law dumped a few in his pond and now the pond is filled with them. He feeds them dog food pellets and when they come fo them the whole area is filled with them.
He can catch 50 with a dipnet in 10 minutes. They just keep getting bigger too.
