During routine tank maintenance today, I measured the turtles.
Measuring the length of their carapace they are:
2 and 5/16 inches – Rex
2 and 1/8 (2 and 2/16) inches – Cinderella
Cinderella hasn’t grown in the three weeks since my last measurement. It’s pretty weird since her carapace felt a bit pyramided. Rex’s was fine though.
