The cherry barb, Puntius titteya is a tropical fish belonging to the spotted barb genus of the Cyprinidae family. It is native to Sri Lanka, and introduced populations have become established in Mexico and Colombia. The cherry barb was named Puntius titteya by Paul E. P. Deraniyagala in 1929. It has also been referred to as Barbus titteya and Capoeta titteya.
The cherry barb is an elongated fish with a relatively compressed body. It is fawn-colored on top with a slight greenish sheen. Its sides and belly have gleaming silver highlights. A horizontal stripe (brownish black to deep bluish black) extends from the tip of the snout through the eye to the base of the caudal fin. Above it is an iridescent, metallic line, gold at the front turning to blue or sea green toward the tail. Males are redder than females, and they attain a very deep red color when breeding. Often the dominant male will have the brightest red colour. Females are lighter, with yellowish fins. The cherry barb will grow to 2 inches (5 centimeters) in length.
he Cherry Barb's natural environment is one of heavily shaded, shallow, and calm waters. Their native substrate is one of silt with leaf cover. They are from a tropical climate and prefer water with a pH of 6.5 - 7.0, a water hardness (dH) of 6.0 - 10.0. and a temperature range of  (22 - 26 °C).
This peaceful cherry-red fish is most often kept in community tanks by fish keeping hobbyists. The cherry barb is a schooling fish and is best kept in groups of five or more individuals. The schools are often less discrete than with many types of barb. It is also best to keep a ratio of two females to one male. The male will constantly harass the females to breed, and by this ratio, it gives the females a small break. They live an average of 4 years, with a maximum lifespan of 5-7 years. They prefer a tank with abundant plants (about two-thirds to three-quarters of the tank), but they still need open space to swim. They tend to hide and will often withdraw under the cover of plants. Younger males are generally peaceful, but they can be aggressive in spawning with females. Appropriate tank mates include Rasbora and similar peaceful fish.

樱桃鱼体呈纺锤形,稍侧扁,尾鳍呈叉形,体长可达5厘米。樱桃鱼从头的前端起至尾柄基部有一条两边呈锯齿状的黑色纵向条纹。背部为紫红色,腹部为淡黄色,全身基本为玫瑰红色,故称为红玫瑰鱼。樱桃鱼在发情时出现的婚姻色更加鲜红,如同樱桃花一样,故又称为樱桃鱼。樱桃鱼色极艳丽,小巧玲珑,深得热带鱼爱好者的喜爱。
樱桃鱼的雄鱼有互相排斥的习惯,但不互相攻击,它们排斥的主要方法是:当两条雄鱼在一起,它们便会各自旋转,并增加婚姻色,以显示自己的美丽,取得雌鱼的好感。
樱桃鱼性情温和,适宜与其它品种的小型热带鱼混养,但有领域感,会对入侵者进行驱赶,此点注意。
樱桃鱼对水质不苛求,适宜生活在22-26℃的水温中。樱桃鱼吃动物性饵料,不择食。樱桃鱼胆小怕事,声音过大时,它们便躲藏起来,但有时它们也爱在水面蹦跳,所以饲养樱桃鱼的鱼缸一定要加缸盖,以防它们蹦出。
樱桃鱼的睃雄鉴别比较困难,其主要鉴别方法是:雄鱼细看时会看到其尾鳍微红,身体颜色鲜艳;雌鱼尾鳍淡黄,身体颜色较淡,身体较粗壮。
樱桃鱼是卵生鱼类,繁殖比较容易。繁殖缸尺寸为39*30*24厘米,繁殖水温以25℃左右为宜,水的硬度为6-10,酸碱度为6.5-7.0。繁殖前应先在缸里铺一层金丝草。然后将经过认真挑选的亲鱼按雌雄1:2的比例放进繁殖缸里。亲鱼入缸后异常活跃,雌雄亲鱼都会出现美丽鲜红的婚姻色,它们追逐蹦跳,有时会跃出水面,所以应加上缸盖,以免发生意外。经过追逐后,雌鱼排卵,雄鱼射精,使卵受精,受精卵比水重,沉入水底粘附在金丝草上。每对亲鱼每次可产卵150粒左右,多者可达300粒能上能下,产卵结束后,应将亲鱼捞出另养。以免它们吞食鱼卵。
受精卵经过约24小时可孵化出仔鱼,仔鱼再经过24小时可发育成能游动摄食的幼鱼,这时应喂以“洄水”,10天后可改喂小型鱼虫。
