I’m not gonna breed him or anything, just all the discussions I read about these and the different types peaked my curiosity when I got him, so I waited until he got bigger to see if he was identifiable. No biggie, I like him ( becoming one of my favorites) and like you said, that’s all that really matters.You are correct, you will never really know for sure.
Unless you plan to breed him and distribute the fry I wouldn’t really worry about what he is technically. If you like him that’s all that really matters.
