Both of my fish were discount bin fish ($40 for the tat, $65 for the scomb) that were written off as unsalvageable. They were both rough and the tat had permenant internal clouding of the left eye. They were both about 8" when I sold them.
As for over 12", you'd have to show me a scomb or tat that is unquestionably over 12" for me to even talk about it. I've never seen one and I'm no spring chicken. Even in the wild, scombs don't get over 12" and tats don't get over 18". I've never seen one in captivity that even got to those sizes.
Chicx, you don't think tats can get over 12" in a aquarium? Idk how big it is(supposedly 16+ inches) but here's one of the bigger ones I've found on mfk.
