Looked on line and seen my turtle is is not an Asian soft shell,But a spiny Gulf turtle it said that the males shell gets to be 9 to 12 inches and the females get twice that size, I hope mine is a male because the color is suppose to not fade away.The females turn all brown when they mature. I will try to see what sex it is if it would stop swimming around for a minute or he is lying on the bottom.also hope its a male so it does not get that big.
