yeah, its a male kennyi, and dont feel bad, mine rules over all in my tank too. best way to cool his jets is to get about 3 females for him to fancy over. you'll end up with a ton of fry if you do this, but they are a popular fish and if you have a few lfs's that are willing to take them, and the time yourself to do it, you can usualy make enuff $$ to kinda offset the cost of running your tank (i.e. food and filter supplies) most lfs's will give you store credit, but dont think your get rich off of them either. i usually get .50 - 1.00$ for each, around 1 1/2". if you let them grow out bigger, the more they will give you
