I've owned and seen a few wild-caught midas and they look a good bit different from the tank-raised-for-several-generations midas. Other than being very shy, sometimes, wild-caught midas have almost no hump and a very evenly-sloped, yet blocky, head. You see these tank-raised monsters with huge humps and great big, almost concave heads. Is it just selective breeding? If so, where are the few wild-caught males that have huge humps that are chosen to sire the future generations of the big-headed monsters?
