Appearance and Identification
Light, translucent blue captive color morph with softer pigmentation than darker blue lines; intensity varies among individuals.
Aquarium-trade color morph of Neocaridina davidi, not a separate species. Distinguish it from darker Blue Dream or Blue Velvet lines using breeder provenance and representative images.
Females are generally larger and have a broader abdomen used to carry eggs.

Use a mature, stable aquarium with biofilm, plant cover, protected filter intakes, and gentle flow. These shrimp are hardy, but new tanks, copper in water or medication, and sudden changes are the usual causes of loss.
Behaviour and Tankmates
Peaceful and continuously active as a surface grazer.
Not a schooling species, but normally kept as a colony.
Not normally territorial.
Small fish may consume shrimplets.

Water Parameters
Neutral to slightly alkaline, moderately hard water suits these shrimp. Keep GH and KH within range to support moulting, and avoid sudden changes.
Parameter caveat
Stable conditions and careful acclimation matter more than repeatedly adjusting water to chase exact values.
