A Dynamic Contrast of Color and Clarity

Blue Rili Shrimp are one of the most visually captivating Neocaridina varieties, known for their unique two-tone appearance — a bold blue head and tail section sandwiching a translucent mid-body. This gives them a lively, patterned look that creates dynamic visual interest as they move through plants and décor. Unlike solid-color morphs, every Blue Rili shows its own artistic markings, adding personality to every shrimp in the colony.

Their youthful energy, constant grazing, and striking markings make them outstanding for aquascapes centered around movement and bold accents. They create excellent visibility even in heavily planted tanks where other shrimp may blend in.

Color, Behavior, and Development

Blue Rili shrimp coloration varies slightly with genetics, diet, and age. Juveniles typically begin with lighter blue patches which intensify during molting and maturation. The central transparent band highlights the digestive tract, making feeding activity visible — a fun and fascinating feature for shrimp keepers.

They are calm, active grazers that flourish in groups. Their pattern stands out exceptionally well against mossy textures, river stones, and botanicals, creating endless opportunities for vibrant aquascape design.

Care, Feeding, and Ideal Conditions

As with all Neocaridina, Blue Rilis thrive in stable, mature aquariums with well-established biofilm. Consistent GH and KH values ensure proper molting and shell health. Their diet includes algae, shrimp pellets, spirulina-based foods, and blanched vegetables. Nutritional support from botanicals such as almond leaves and cholla wood helps both juveniles and adults remain vibrant and active.

Because color expression is partly genetic, maintaining high-grade broodstock and separating culls helps ensure long-term pattern consistency in your colony.

Bonus Tip

For the boldest contrast and cleanest pattern, keep colonies on dark scapes with high-quality food sources — this encourages both deep blue head/tail coloration and strong transparency through the center band.
