It does look shorter than normal to my eye. I don't think there is anything wrong with short bodied fish. What we call a deformity - (line breeding this specific trait is not what I'm referring to, rather the natural rare oddity of a SB fish.) Nature might call it evolution, like when the all the crabs with tiny claws laughed at the new crab with huge claws. Then the crab with the huge claws crushed the other crabs and eat them with his new big claw.
