Kissing Gourami don't kiss in the usual sense; meaning a show of affection or sexual attraction. Kissing Gourami males kiss as a display of dominance. Many fish actually do this, especially cichlids. It's called "lip locking" and it's a form of wrestling. But the big, fleshy lips of Kissing Gouramis make it look more like a kiss than the bite that it really is!
