Alright, here's my later entry:
This guy is, literally, a big fish in a small pond. A small pond of small fish.
This is my largest, dominant male multie (N. Multifasciatus). I received 6 of them last Monday, and this guy is the biggest at just over 2 inches; the others barely hit 1.5. He pretty much owns the tank, to the point where he nearly harassed the other male to death until I put him in a breeder box. When someone walks by all the fish hide near their shells, but he is always the first one in open water. In fact, the other fish won't even come out of their shells unless he is out and swimming actively. Now I'm just waiting for him to spawn with one of his mates.
