Cool morn ,,, I have a friend who as since moved that had a pond .. Feeder goldfish and a Koi I had that got to big for my tank ..>> Heron tried to stalk that pond but everyone was too big .

Well ,, then I gave him a blue channel cat ,, that also outgrew my tanks .

Well he was only clean up fish in pond and died happily eating fish poop . Floated to the top 2 days later ....
