Since I have kept aquariums, I have been looking for adding other creatures other then just the fish. So far I have snails, shrimps and of course fish.
I actually had the temptation to buy hermit crabs too. It sounds fun just by the idea of it. However, when I read a lot of reviews from the owners, many of them claim the hermit crabs are boring since they spend most of their time hiding in the shell and not moving at all.
From what you have experienced first hand, it seems to be quite the opposite of boring? 
Where did you get your hermit crabs?
If I ever get them, it will be after I start a marine aquarium. All my current aquariums are freshwater.
