美丽真小鲤（学名：Cyprinella formosa）为辐鳍鱼纲鲤形目雅罗鱼科真小鲤属的其中一种，分布在北美洲美国科奇斯郡和圣贝纳迪诺河的水域中。在1969-70年间曾短暂地从美国灭绝，但又被重新引入亚利桑那州和西南部的其他地区。圣贝纳迪诺野生动物保护区一直在努力恢复这种受威胁的物种，将其重新引入科奇斯郡周围的各个池塘。在1990年重新引入后，已经从科奇斯郡扩展至墨西哥索诺拉，该物种也可以在Rio Yaqui和Mimbres河中找到，本鱼体细长而侧扁，有尖的鼻子，侧线略微弯曲，有30至40个小鳞片，背鳍和腹鳍只有8条鳍条，而臀鳍条则从8-9枚不等，体橙色或鲜红色的，沿着侧线有银灰色的侧线条纹，在交配期间，雄鱼会将它们的尾鳍变成黄色或橙色，雄鱼有时可能有蓝色或红色的头，^[1]^[2]^[3]^[4]^[5]^[6]体长可达9公分，栖息在沙石底质的溪流底中层水域，以有机碎屑、水生无脊椎动物为食，繁殖期在5至7月。^[7]
