Very nice fish, I very much agree with Hao that it is the same fish. That is actually very cool to see a fish with so much history
As for the size piece, It is only topical when very large sizes are put out there. To the OP it comes with the territory and not a sign of disrespect. Fish that size are very rare and having one is special, you know as well as any of us, that many fish sizes are rounded up on forums and FB. I have several large ones that have been questioned over the years and I understand why as one in particular is abnormally large for its species. Like you I am not willing to stress it and net it out of the tank but happy to show pics that illustrate its size. Hell I have about 2000 pics of my fish. Ultimately it’s your fish and a great fish, enjoy it but understand.
