Unless that guy has hands like paddles then that fish is around the 19-20" mark. No chance its near 2 foot.
Maybe you should take a trip over here and see for yourself. Mel takes care of his fish, the video does NOT do his fish justice. I have a WC pair that is a little over 2 years old and my male is about 15". I would say Mel's is easily about twice the size of mine. He is MASSIVE. Don't doubt it when he says size, he is almost right on. If you were able to see that 8" male that he referenced in the video, you would of thought that is was only 4", because of how small it is next to the big guy.
Unless you have actually seen his fish with your own eyes, its easy to say BS. But dont, he is spot on.
