  Head bumping is a way of showing dominance. "I've got a better head than you — nyah, nyah, nyah!" Since it's hard to watch the bumphead parrotfish, you might want to try an aquarium with some "kissing" gouramis (Helostoma temminckii). While they can get big, I keep 3 medium size (4″ long) in a 20 gallon long tank and they often show their dominance by, you guessed it, "kissing". They form their mouths into a kissing position and then push against another gourami's mouth. They can keep up at this for 5 to 10 minutes, quite like young teenagers.
