蓝星鱼 lán xīng yú 丝鳍毛足鲈

蓝星鱼的学名为丝鳍毛足鲈Trichogaster trichopterus (Pallas, 1770) ，隶属于归属于鲈形目（Perciformes）攀鲈亚目（Anabantoidei）丝足鲈科 （Osphronemidae）。原产中国云南，老挝，泰国，柬埔寨和越南的湄公河流域。该鱼腹鳍已退化为长丝状物，故又名丝足鲈。其体侧有三块极其鲜明的黑色圆斑，一个在鳃盖后，一个在躯部中央，一个在尾柄基部，把鱼体装饰得非常俏丽。三块圆斑就象三颗黑色的星星，镶嵌在蓝色的天空中，故被赞为三星鱼、蓝星鱼或蓝三星。常见的蓝曼龙是三星鱼（蓝星鱼）Trichogaster trichopterus (Pallas, 1770) 的人工变种品种。

The scientific name of blue star fish is Trichogaster trichopterus (Pallas, 1770), which belongs to Osphronemidae, anabatoidei, Perciformes. It is native to the Mekong River Basin in Yunnan, Laos, Thailand, Cambodia and Vietnam. The ventral fin of the fish has degenerated into a filament, so it is also known as the sea bass. There are three extremely bright black round spots on the side of the body, one behind the operculum, one in the center of the body, and one at the base of the tail handle, which decorates the fish very beautifully. The three round spots are like three black stars embedded in the blue sky, so they are praised as three star fish, blue star fish or blue three star. The common blue man dragon is an artificial variety of the Trichogaster trichopterus (Pallas, 1770).
