Interestingly enough, I just brought one home from a snorkel trip to the Florida Keys. I see a lot of 'tidal' chitons that live along the water line on rocks. But when I brought a couple of them home, they literally climbed right out of the tank! The one I collected this weekend was on a rock in 5 feet of water and much lighter color than the ones I tried before. I'd love it if the new one would reproduce, but I'm not expecting it.
