I will be the first one to say that I suck at picking out subtle differences in fish. I have owned several scombs and 3 tats now. And honestly if I seen this fish in the lfs and I did not see a colored adopsie fin i would think it was a scomb. But now that you all have pointed these things out I look back thru all my past scomb pics and Tat pics and I can start to spot the differences. -----------thanks alot
