About the species

Blue Red Rili is a two-toned variant of Neocaridina davidi where blue and red markings are combined in the rili pattern on the same body. Every individual turns out unique, giving a lively and varied colony. Care is just as simple as for other Neocaridina.

Recommendation

Blue Red Rili suits anyone who appreciates variation rather than a uniform colour. Because the pattern is unstable the offspring will vary in appearance — that is part of the charm. A light substrate and good lighting let both colours show.
