Neocaridina davidi 'Blue Dream'
A deep solid-blue Neocaridina line. Care is identical to Red Cherry. Keep separated from other Neocaridina colour morphs to prevent reversion to wild grey.
Blue Dream Shrimp (Neocaridina davidi 'Blue Dream') reaches 2.5–3 cm and needs a minimum tank of 20 L with a colony of 10+. Native to Selectively bred (Neocaridina lineage). Aim for 18–28 °C, pH 6.5–8.0, 6–15 dGH, and 150–250 ppm TDS. Lifespan: 1.5 years. Breeding: very easy, same as red cherries. Diet: omnivore / detritivore, Biofilm, algae, blanched veg, sinking pellets, calcium supplements. Plant-safe: Yes. Tank-mates: Nano fish only, same as Red Cherry.

Weighing it against something similar? Compare Blue Dream Shrimp head to head:
Hard-won lessons from the tank.
Blue Dreams revert to wild brown more easily than Cherry — keep colonies extra-pure. Strong colour requires good nutrition: high-protein shrimp food, spinach, calcium supplements. Display them against light-coloured substrate (sand) for maximum visual pop.
What can go wrong and how to spot it.
Failure modes, in order of how dramatic the fix is.
Same susceptibilities as Cherry shrimp.
1) Mixing with Cherries — fast colour reversion. 2) Confusing with 'Blue Velvet' which is a different colour line and a different gene. 3) Buying from cheap mass producers — colour line stability suffers.
The practical routine, read top to bottom.
Identical to Cherry shrimp. 20 L+, cycled, stable, copper-free, with moss and hides.

Selectively bred Neocaridina davidi — no wild equivalent.
How they pair, reproduce, and grow.
Same as Cherry shrimp — females larger and rounder with saddle.
Every 3–6 weeks. Same as all Neocaridina.
Direct freshwater development — same as Cherry shrimp. 20–30 eggs per clutch, ~30 days to hatch.

Minimum tank: 20 L with a colony of 10+. Blue Dream Shrimp (Neocaridina davidi 'Blue Dream') reach 2.5–3 cm as adults.
Target 18–28 °C, pH 6.5–8.0, 6–15 dGH, and 150–250 ppm TDS. Mature, cycled, low-nitrate water is non-negotiable.
Tank-mate notes: Nano fish only, same as Red Cherry. Plant safety: Yes.
Breeding: Very easy, same as Red Cherries. In a stable colony of 10+ adults you will see berried females naturally once parameters and food are right.
Diet: omnivore / detritivore, Biofilm, algae, blanched veg, sinking pellets, calcium supplements. Algae-eating rating: 4/5.
Typical lifespan: 1.5 years.
