Jordanella floridae
American Flag Fish
美国旗鱼
The flagfish or American flagfish, Jordanella floridae, is a killifish native to Florida. It received its name because the male fish resembles the American flag, with a large black/blue dot and alternating red and black/blue stripes on its body. It is a common, native fish in Florida that is occasionally found in fish stores. They make quick work of hair algae and they may also eat plants in a planted aquarium.


体形似月鱼,但背腹宽阔,尾柄亦宽。头吻部钝圆。尾鳍外缘平直。背鳍大于臀鳍,背、臀鳍缘弧形,体色多变,有红、淡黄、蓝、紫红等色,有深有浅,有偏蓝或偏红,满身有10余条纵向星点条纹,背鳍上布满深色星点,其星点条纹很像美国国旗星条图案而得名。
美国旗鱼可耐18-22℃低温,食性很杂,除摄食动物性活食外,也吃配合饲料,还需嫩叶等植物性饵料。喜阳光,对水质不苛求。性情活泼,可以和其他鱼混养。同种鱼宜雌雄鱼均衡。
雌雄鱼容易区别,成熟生殖期的雄鱼体色艳丽,处在发情阶段的雄鱼,体上星条纹散乱不齐;雌鱼体色较暗,腹部宽大肥满。产卵箱中要有水草、砂粒和增氧设备。雌鱼排卵延续6-7天,每天10-20余粒不等。然后捞出雌鱼,留下雄鱼,雄鱼极其爱护后代。增氧器轻轻增氧,不要停止。1周左右,仔鱼陆续破膜而出。
