Hello, I was wondering if I could get your opinion on what sex Sinclair may be leaning toward. His plastron looks concave, (I tried to get it in the picture though it is more evident in person), and the area around his vent is V shaped. However, his tail seems oddly short for a male so it kind of throws me off. He is 2 and a half years old and is nearly 11in nose to vent (when his head is out a relaxed amount), weighing roughly 6.5lbs. I appreciate any tips you may have to offer.
