Most fighting fish species are brightly colored and eye-catching in appearance. Both males and females of Taiwan's native paradise fish have ten vertical blue bars along their gray-green bodies, intermingled with a pale red hue. In sunlight this coloration creates a shimmering interplay of blue and green velvet sheens.
鬥魚多半擁有斑爛奪目的外型，台灣鬥魚，不分雌雄，灰綠色的身上鋪滿了十條藍色橫帶，間雜著淺紅色調，在陽光下交替變換藍、綠絲絨般的光澤，十分悅目。
