Think I'll steer clear of the hermits. I hear and read more negatives than positives about them. I also want a pistol shrimp eventually. I have 1 in my 14 that snaps all night long. That's the only way I know it's still around. Entertaining in an odd sort of way. Having 1 in my other tank will b twice the fun. Haha. I'm going to wait until my tank matures before buying another. I have no clue what he eats. There's no waste after feeding. Must be an excellent scavenger.
