Me and AG cleaned aquarium today and measured their size.

Rex is growing by leaps and bounds, Cinderella is slowly chugging along. They’re both growing so fast, the 5-gallon tank is going to be too small for them much sooner than expected…gotta start thinking more about the (around) 200 gallon tank soon…

Measuring the length of their carapace they are:
1 and 3/4 inches (1 and 12/16) – Rex
1 and 1/2 inches (1 and 8/16)- Cinderella
