polomax24;1126615; said:GT's hump comes and goes, and has nothing to do with being wild. The subdominant or young males often don't show any hump.
Here is a picture of my male when he was the dominant GT in the group.
A month later, he lost his hump...
Still in the second pic his head still has a steep slope downward in the front. Its not rounded from front to back like females.......
