A Bold Spark of Ocean Blue in Freshwater

Blue Diamond Shrimp are one of the most dramatic and visually striking Neocaridina color morphs. They exhibit a rich, deep navy-blue to cobalt hue that appears solid and glossy when healthy and fully mature. Their coloration transforms any aquarium into a miniature underwater galaxy, where flashes of sapphire dart through green plants and shadowy driftwood. Their confident visibility makes them a standout choice for aquascapers who appreciate rich, jewel-like coloration that is both bold and relaxing to observe.

These shrimp are hardy, peaceful, and actively graze throughout the day. Whether patrolling moss, sifting through substrate, or exploring wood textures, they help maintain tank cleanliness while providing endless movement and charm. Their sturdy nature and stable color lines make Blue Diamonds a popular pick for showpiece shrimp colonies.

Color, Behavior, and Development

Blue Diamond coloration often begins as lighter gray-blue in juveniles, developing into a solid, opaque blue through maturity and improved water stability. High-grade adults glow with a dark sapphire sheen that may show slight teal undertones under different aquarium lighting. The pigment is concentrated throughout the entire shell, including legs and tail, which distinguishes them from lower-grade blue lines that retain transparency.

They thrive best in environments with dense plant growth and hiding spots that support safe juvenile development. Social and calm, Blue Diamond Shrimp flourish in groups and are well-suited to species-only tanks or community setups with gentle nano fish.

Care, Feeding, and Ideal Conditions

A cycled, stable aquarium with biofilm-rich surfaces supports the long-term health and vibrancy of Blue Diamonds. They eat algae, detritus, biofilm, and shrimp-specific prepared foods. Supplements containing spirulina and color-enhancing ingredients such as astaxanthin contribute to deeper color saturation and stronger shells. Gentle filtration and stable GH and KH levels ensure healthy molting cycles and continuous colony growth.

Botanicals including almond leaves, lotus pods, and cholla wood help generate microfauna, which is essential for the survival of young shrimp and supports natural foraging behavior that enhances health and coloration.
