Your attitude and reproduction in captivity is fairly straightforward and has, along with a traded under the name of Red Cherry Shrimp or Red Fire Shrimp red color form, found in Europe -wide dissemination in the aquarium hobby. Since commercially several members of the genera Caridina and Neocaridina offered under the name Rückenstrichgarnele, a conclusion to their actual species membership is often not possible without further notice.
Dissemination
About their original habitat in lakes and small and medium rivers in eastern China addition, the Rückenstrichgarnele is now also available in other parts of China, Japan, Taiwan and Hawaii. Within China, the species was spent stocking fish from Taihu Lake in other inland waters, in Hawaii it could spread through the release of originally offered as ornamental fish fodder copies. In Taiwan, the animals are increasingly also as fish food. Since the Rückenstrichgarnele to low water temperatures is robust, there is a risk of reintroduction by former holder in Europe.

The coloring of the Rückenstrichgarnele is extremely variable, ranging from black, brown, red, dark green and bright white to transparency. A drawing is possible, but not mandatory. A dorsal longitudinal line on the abdomen of the female animals, as he was name-giving here is to be found in many other freshwater shrimps and does not constitute sufficient Artmerkmal represents the Rückenstrichgarnele reached a total length up to 28.5 mm which up to 6.5 millimeters the carapace omitted. Male specimens usually remain smaller and less plump than their female counterparts. The Uropodenfalte is staffed with ten to 21 spines. In males the ratio of length and width of the endopodite is ( paddle-like branches of the swimming legs ) on the first swimming leg pair about 1.2. The edentulous tip of the rostrum does not extend beyond the end of the antenna base, the Rostrumformel is 2-3 7-19 (14-16) / 1-9.
Way of life
The peaceful and very adaptable species feeds on decaying plant material and growth on very small invertebrates and insect larvae. You propagates during the warmer season. From 20 to 50 about 0.55 to 0.58 × 0.85 to 1 millimeter eggs hatch already a ground oriented lifestyle adapted larvae. Dorsal stripe shrimp have a life expectancy of about 1.5 years.
Cultivated forms
Especially in the hobby have already mentioned red ( Neocaridina heteropoda var red) and a yellow color form ( Neocaridina heteropoda var yellow) emerged, referred to colloquially as Red Fire or Yellow Fire. The latter are often simple to find in the trade under the name Yellow Shrimp. Animals with particularly closed, if possible, the extremities comprehensive staining as Sakura (red) or neon ( yellow) respectively.

Recently found in the trade and an orange cultivar under the name Orange Sakura. In addition, there are discussions on a Black Sakura, so a black cultured form of which is not clear, however, whether it is a erbfesten color shock. Next are " Rili Red" or " Blue Rili " - offered shrimp, which are also for breeding forms of Neocaridina heteropoda: Here is the actual color of the shrimp is interrupted by a pale - white central section. It was a pure bluish cast read ( "Blue Jelly " or "Full Blue Rili ").
