I love them, got dozens, of all shapes and sizes. I just picked up one last week, for five bucks, abuot 3 inches around, red body with white and red spots all over the legs, with sticky hair. Sand clings to him and he does nothing but eat sand and poop.
I saw him followng my tiger tail cucumber the other day, and the tiger tail was consuming tons of sand, and pooping sand pellets, (think rabbit pellets), and teh crab was recycling them again.
Kinda reminded me of a tunnel boring machine, in that the sand was being displaced some ten inches.. from where it started...
great looking crab this last hermit is, he will sit there and stare back at me with teh flashlight on...
