Shell size

First off I have no pictures of her from this incident but i do have a picture of my lovely lady, I tried to measure her shell opening because she’s getting her own shells (trying to kiss the painted shell a forever goodbye). Within the few seconds of be being able to get the tape measure she was up my arm. She is a pretty big crab i’m estimating maybe 1 7/8 maybe 2 inches. The other one around her size is an inch and a half, however she just molted and dose not fit in the shell completely that she has on and it is bigger then an inch and a half. Anyone’s input on what size they think i should hunt for would be awesome.

just incase here’s the measurements again crab in painted shell: - current shell too small (1 1/2 inch) - crab around her size ( 1 1/2 inch)

 SHE ALSO JUST MOLTED
