A Hungarian researcher has listed ten modes of combative behavior in paradise fish. They include displaying at a distance; pushing their heads against each other like fighting bulls; swimming in parallel in the same direction, body to body; then displaying head-to-tail, pecking each other, and going into a mouthlock for over two minutes.
匈牙利學者曾經列出十種蓋斑鬥魚的較勁模式，從遠距離展示、鬥牛般的頭對頭互頂、同一方向近距離平行貼身游動，彷彿比賽泳技，再到頭對尾展示、互啄、與超過兩分鐘之久的嘴咬嘴拉扯。
