Actually, I didn't hatch the one I have been posting pictures of. This one was hatched by Eric Holt.
However, I have hatched many in the past and I didn't experience diapause with them. I incubated the eggs I got years ago at 82 to 85 degrees. In fact, I kept the eggs in with redfoot eggs and they did fine. But now that I think about it I did get widely differing incubation times. At any rate, they are quite easy to hatch using standard mud/musk turtle incubation techniques.
I start hatchlings on live brine shrimp and frozen blood worms. They quickly go over to just about anything after that.
