The rosy barb (Puntius conchonius) is a subtropical freshwater fish belonging to the minnow family (Cyprinidae). It originates in Bengal, India and other parts of Southeast Asia. This pinkish fish is one of the larger species of Barbs growing up to 6 inches in length. Their color becomes bolder during their mating periods. The male has a brighter pinkish color and the female is slightly plumper. Also note that females do not have any reddish color in their fins while males do. They may weigh up to 12 oz when fully grown but can weigh much less during adolescence. They are mature at 2.5 inches. The rosy barb is an active, peaceful species well-suited for a community aquarium. It is considered one of the hardiest barbs, undemanding and beautiful, and most impressively colored during the mating period. It can be kept together with other small fish but can be aggressive toward other fish and nip their fins. They will eat most foods provided to them. They are best kept in groups of 5 or more in an aquarium with a length of at least 30 inches. They usually reach a maximum size of four inches. Using a dark-colored gravel will show off the color of the fish.

玫瑰倒钩, 鱼体纺锤形,野生条件下可达14-15厘米。侧扁,尾鳍呈叉状。幼鱼体上泛银白色,随着成长,背部为银白色,其余部分均为红、黄、绿色相间,在阳光照射之下,闪闪发亮。后身有一黑圆斑,背鳍上也有黑斑。繁殖期间出现婚姻色,雄鱼全身呈玫瑰红色,鲜艳美丽。有长尾与短尾两个品种,由于其性情温和,颜色艳丽,历来享有热带金鱼之美称。
玫瑰倒钩可耐16℃低温,可适应中性水质。喜欢水草茂盛的水体和老水,不宜一次大量换大,宜定时定量换水。杂食性,不挑食。性情活泼好群,玫瑰鲫鱼从不攻击其他品种的热带鱼,是混养的好品种。食动物性饵料,但不择食。
雌雄亲鱼容易区别,雄鱼体型细长,体色鲜艳,背鳍、腹鳍、尾鳍都宽大且长,有艳丽的婚姻色;雌鱼色泽较浅较暗,体幅宽厚,腹部膨大。水温比平时提高1-2℃,产卵箱底铺鱼巢。雌鱼产粘性卵300-400粒,也要防止鱼卵被吃掉。受精卵经24-38小时孵出仔鱼,再经3天开始游动觅食。
