Neocaridina davidi 'Blue Dream'

Selectively bred (Neocaridina lineage)Beginner

TL;DR, Blue Dream Shrimp

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.

Who it lives with

Tank-mate safety and the species this one is documented to thrive (or fail) alongside.

Good tank mates

Same as Cherry shrimp — best species-only.

Avoid

Other Neocaridina colour morphs (will revert colour). Same fish exclusions as Cherry.

Pro tips

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.

Common mistakes

Common mistakes

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.

How to care for it

Behavior & breeding

How they pair, reproduce, and grow.

  1. Stage 1
    Telling them apart

    Sexing

    Same as Cherry shrimp — females larger and rounder with saddle.

  2. Stage 2
    Molting cycle

    Molting

    Every 3–6 weeks. Same as all Neocaridina.

  3. Stage 3
    Life stages

    Lifecycle

    Direct freshwater development — same as Cherry shrimp. 20–30 eggs per clutch, ~30 days to hatch.

Color grades / variants

Lowest to highest: Blue Velvet (lighter, sky blue, often transparent legs) → Blue Dream (deeper royal blue with opaque legs) → Blue Dream Vivid (deepest, fully solid blue).
