胖头鱥（学名：Pimephales promelas）是辐鳍鱼纲鲤形目雅罗鱼科的其中一个种，广泛分布于北美洲，从加拿大魁北克省至不列颠哥伦比亚省、西北地方，南至美国阿拉巴马州、德克萨斯州、墨西哥淡水流域，本鱼体细长且侧扁，头圆钝，口近端位，通常呈暗橄榄灰色，背部和侧面有一条暗色条纹，腹部颜色较浅，背鳍中部有一个暗色斑点，繁殖期雄鱼在颈背上长出一个大的灰色肉质生长物，在鼻子上长出大约16个白色的繁殖结节^[2]，背鳍软条8枚、臀鳍软条7枚，体长可达10.1公分^[3]^[4]，寿命可达5年，栖息在河川、湖泊、沟渠、水塘、沼泽，能忍受混浊、低氧的水域，属杂食性，以藻类、昆虫、甲壳类及有机碎屑等为食^[5]，单独或成群活动^[6]，繁殖期在6至8月，雄鱼会筑巢，当雌鱼产卵后，雄鱼会守护巢穴。本种鱼常被当作饵料鱼，最近在水族馆贸易中有玫瑰红的变异出现，这种颜色变异于1985年在美国[[阿肯色州的几个养殖场被发现。该品系的雌雄都有玫瑰金色的身体和鳍，可能表现出野生型的深色斑点，可作为观赏鱼^[7]。
