蓝虎纹虾是 Caridina mariae 的橙眼蓝色品系，原种分布于广东、香港及越北山溪。成体 2.5–3 cm，20–26 °C 清洁软水（pH 6.0–7.2），比水晶虾略宽容；可淡水繁殖。
Blue Tiger Shrimp is the blue morph of Caridina mariae, a hill-stream atyid from Guangdong, Hong Kong and northern Vietnam whose wild form is banded in black and cream. Taiwan breeders selected the blue-orange-eyed strain in the 2000s, and the best specimens are now a vivid sky-to-royal blue with the species' signature glowing orange eyes — the combination that made 'Orange-Eye Blue Tiger' one of the most sought-after caridinas of the last two decades. It grows slightly larger than bee shrimp at 2.5-3 cm and is a little more forgiving than the cantonensis line: 20-26 °C, mildly acidic to neutral soft water around pH 6.0-7.2 and 4-8 dGH, clean and stable but not as knife-edge as crystal shrimp. In the aquarium it is active, hardy and a constant algae grazer over wood and stone. Breeding happens in freshwater, though clutches are modest and the fry develop slowly. A group of blue tigers over dark stone with moss is one of the classic displays of the Asian shrimp hobby.
