Red Dead Redemption The Legendary catfish answer
Red Dead Redemption Two
The Legendary catfish
Like many I thought that I needed to catch the legendary catfish, but I did not, because it does not need to be caught.
When I finished the side mission “A fisher of fish – II” The Legendary Channel Catfish was added to my list of caught fish, completing all 15 of the legendary fish listed in the Compendium section of the game.
The legendary catfish is listed as the legendary channel catfish, but it is the last legendary fish that can be caught, I think that Jeremy Gill got caught by the legendary catfish, and that gave me the fish as caught. So stop fishing for it, it is not there.
