Neocaridina heteropoda var. "red" or cherry shrimp is a variety of freshwater shrimp from Taiwan which is commonly kept in aquariums. The natural colouration of the shrimp is green-brown, however the red morph is much more frequently sold
The shrimp spends a great deal of its time sitting on aquatic plants, when available, and hiding in them for protection, especially after moulting. They also eat the film of algae and micro-organisms which forms on plant leaves without harming the leaves in the process. Java moss and Java fern are both excellent plants for the shrimp tank, as they thrive in the same conditions that the cherry shrimp do and provide both the physical benefits of the plants to the shrimp and pleasing visual contrast with the red bodies of the shrimp to the human viewer.
The red cherry shrimp is a non-aggressive shrimp. They are active throughout the day, and can be seen grazing on algae, aquarium décor or the sides of the tank, hunting detritus among the gravel, and sometimes even mating. Periodically a shrimp will shed its exoskeleton, leaving an empty white ghost of itself caught in the plants or drifting around the tank. This should be left in the tank, as the shrimp will eat it to recover the valuable minerals it contains.
Female pregnant cherry shrimps tend to hide in the dark. If they feel endangered by predators, they will abandon their eggs. They need an environment with wood or plants such as Java moss to hide themselves and their babies in. When they are carrying the eggs under their bodies, they can be witnessed circulating water over the eggs with their legs to ensure good health.

樱花虾又叫樱桃虾、玫瑰虾、火焰虾等。樱花虾分布于台湾,以及其他一些东南亚国家。因为体形小,没有带攻击性与破坏性的螯足,食性上属于混合食性,因此,养在草缸里,不会伤害其他生物,还可以清除食物残渣,对水草上附着的藻类做细致的清洁工作
 樱桃虾成虾体长大约1.5CM,水质要求pH6.5左右,最佳水温22-26度,繁殖方式属于大卵型,樱桃虾因为属于大型卵,因此繁殖还是比较容易的,不象小卵型的大和藻虾,繁殖过程需要汽水环境,有一个降温的过程。
性成熟的樱桃虾母虾背部有一个黄色的块,那可不是虾的胃,那是虾的卵巢。
母虾成熟后公虾即与之交配,公虾靠近并追逐母虾,然后居身于母虾的下方作同步游泳,公虾转身向上,两虾腹部相对,头尾一致,但偶而也会见到头尾颠倒的,将母虾抱住,释放精液粘贴至母虾的第3-5对步足间的位置上,公虾将精子注入母虾之生殖器中,母虾的卵巢会逐渐发育成熟。
母虾产卵时做抽搐动作将精子挤出少量,实现体外受精,至此,母虾就开始抱卵了。
樱桃虾刚开始抱卵是金黄色,如果变黑有时是变绿,那就是卵已经成熟,小虾快孵化出来了!
几个星期后,虾宝宝出生了。
有的小虾的刚出生几天就已经可以看出来有一点红了,这些以后长大表现都满不错的,此外通常母樱桃虾会比公虾红的很多。
