The Blue Rili Shrimp is a captive-bred Neocaridina davidi colour morph that presents the distinctive rili pattern — solid colour at the anterior and posterior of the body, with a near-transparent abdomen — in a cool, attractive blue. The blue sections range from pale cornflower to deeper steel blue depending on line quality, and the combination of blue and transparent segments creates a visually interesting, almost fragmented appearance that differs markedly from solid-colour Neocaridina morphs.
The Blue Rili was developed by crossing blue Neocaridina lines with rili-patterned individuals and then selectively breeding for consistent expression of both traits. As with other rili morphs, maintaining a clean and consistent pattern across a colony requires careful selection — offspring without culling will trend towards a mix of solid-coloured, rili-patterned, and unpigmented individuals.
Blue Rili Shrimp are as easy to keep as any other Neocaridina variant. They are highly tolerant of typical aquarium water conditions, do not require specialised RO water, and thrive in community setups with other peaceful nano species. In a planted aquarium with dark substrate, the blue sections of the rili pattern are particularly vivid and eye-catching. The combination of moderate rarity and attractive patterning makes the Blue Rili a popular choice among hobbyists who have mastered Cherry Shrimp and are looking for a more unusual display morph.
