I know we built a bait pond to raise goldfish for river bait, when it had a couple feet of water in it we put a hundred GF in it, water was around 2' dp at the center. GBH cleaned it out in a matter of days, didnt take them long at all. all of the GBH didnt survive but enough did.

And they were a fight from day one to the last day we tried raising them, something about the brightness of them they love them, eat em like candy.

All the really good ideas I've ever had came to me while I was milking a cow.
