Yep. Or a wider "V". Tail size is more of an indicator than the anal scute shape, but either way, they need to be bigger and older before you can be sure.
The biggest difference I have seen is, PB is what I have and PP is what I want. lol... Nice looking little ones you have there. Keep us posted on what you see different in them from what you hear or read!
Very beautiful. Little precious jewels! I love how their shells are developing and a good size to start with so hopefully the fragile baby part is over. Be very sure to do the closed chamber as suggested above by the wonderfully wise experts. It works! Warm and humid = healthy and happy! Smooth shells and well developed kidneys are the goal. Yay! : )
Humidity, warmth and hydration will help the babies grow smooth. They also need a good varied diet, sunshine and exercise. Don't let them get cool with high humidity, even at night. These things are not as critical for older ones that are already smooth. No one knows at what size you can lay off the humidity, but my experience suggests that they must be well over 10" before it ceases to matter as much. Humidity is fine for adults too, even they they can tolerate it more dry.
