Do I need to buy smaller shells?
Recently got another crab that was just slightly smaller in a d shape shell. Little less than 1.5 inches wide opening. Just a tad big smaller than my larger exact 1.5 inch opening crabs. These shells are 1 1/8 to 1 1/4 inches wide in the pics I put here. Do I need to get some 1 inch opening shells for them? It just seems awfully big on them especially when they curl all the way inside like the first picture!
