I forget how long this baby hiding stage lasts. The past few days I haven't even seen an arm poking out. Tonight I was getting a little worried as the last time I put hermit crabs in was several days ago and I only put in 2. Tonight, I spied an arm and upon closer inspection, he's sitting in a shadowed spot watching us for how long, could have been hours! Very secretive. I'm wondering if this is a nocturnal species and I'm still not possative on what he is. So once found out he retreated back into his den. I'm hoping he'll soon start to figure out I'm the Food God!
