Crab changes shells several times even in a day

I clean out my shells, put them back into the tank in a clean area. In the morning the shells have been moved around, and some are even half buried sometimes. Maybe mine likes them covered in sand.

Dwable changed shells for the 1st time, picking a spikey one, of which I joking refer to as Dwable: Attack Mode with my friends. He's already gone back to his original, though.

Yeah I had no idea that they likes a certain type of shell at first! My shell shop... well. I have two. I have one in a shower caddy made to hold soap. It came with suction cups attached and I stuck them to the side of the tank up by the vines and just set some shells in there so they could climb up there and shop. But they seemed to go untouched, so I put a plastic lid on the sand and set a bunch more shells in there. They also usually seem to go untouched. :c I guess my hermies like their shells.
