Neocaridina Davidi: Species Profile and Color Morphs

Neocaridina davidi is the single species behind almost every cherry, blue velvet, jade, and rili shrimp in the hobby. The wild form is a drab translucent brown, and every bright morph on the market is selective breeding. Since all morphs interbreed freely, that one fact should decide how you stock your tank.

One species, dozens of morphs

Breeders have fixed color into stable lines over roughly two decades, and the names are marketing labels rather than biology. Red cherry shrimp remain the default and are graded by color intensity; yellow neons, orange sakura, blue velvets, black roses, and green jades are the same animal in different pigment. Rili morphs carry a clear band across the midbody, a mutation breeders stabilized and split into red rili, blue rili, and carbon rili lines.

Our piece on cherry shrimp grades and why they turn clear covers what the red scale means and what fading signals about your water.

Where the species comes from

N. davidi is native to Taiwan and was sold for years under the name Neocaridina heteropoda before taxonomists settled the current one. It shrugs off conditions that would kill most Caridina species, which is why beginners start here. The full parameter list is in our Neocaridina care and water parameters guide.

Why mixing morphs backfires

Put red cherries and blue velvets in one tank and they will breed without hesitation. Within a few generations the line drifts back toward the wild translucent brown, and the color you paid for is gone. Morph color holds only when lines stay isolated, so serious keepers run one color per tank.

Choosing this species

Against the more demanding bee shrimp, the tradeoffs are simple: davidi lives in ordinary tap water, Caridina generally wants soft, buffered substrate. The Caridina vs Neocaridina comparison spells out the differences in full.
