Blue Rili Shrimp are a patterned color morph of Neocaridina davidi. The Rili pattern — pigmented head and tail with a transparent mid-section — creates a striking two-tone look that differs from solid-colored Neocaridina. Individual pattern expression varies, so colonies tend to look dynamic rather than uniform.
Every Blue Rili Shrimp we ship is quarantined and health-checked at our facility before it leaves. We run over 100 dedicated aquariums on-site. These are not pet store shrimp — they are selected for clear Rili patterning and raised in stable, clean water.
Care Notes
Neocaridina are forgiving, but stability matters more than perfection. Avoid sudden swings in temperature, pH, or GH — drip acclimation on arrival is essential. Do not use copper-based medications in a shrimp tank under any circumstances. Feed a small amount 3–4 times per week; remove uneaten food after 24 hours. A mature tank with established biofilm is the best environment for a new colony.

Breeder Pack Details
The Faster Way to Build a Colony
The Breeder Pack is designed for hobbyists who want a head start on colony growth. More females means more reproductive capacity from day one — a deliberate ratio chosen to give your tank the best possible foundation.

Species Spotlight
Why We Love This Shrimp
01
Two Tones, One Shrimp
Blue Rili shrimp carry a distinctive pattern — blue head and tail sections with a clear, transparent mid-section. The patterning varies between individuals, which means your colony will develop real visual diversity over time.
02
Natural Tank Cleaners
Neocaridina graze biofilm and algae constantly — working every surface of your tank around the clock without any intervention from you.
03
They Breed in Your Tank
In stable conditions, Blue Rili Shrimp reproduce readily. A small group becomes a self-sustaining colony over time — the pace depends on your water and setup.
Community Tank
Compatible Tank Mates
These species coexist peacefully with shrimp. Research before mixing — not every fish is safe.

Expert Advice
Razz Aquatics Recommendation
Blue Rili Shrimp show their patterning best in a planted tank with dark substrate — the transparent mid-section disappears against darker backgrounds, making the blue sections appear to float. Java Moss or Anubias provide grazing and cover for shrimplets. A sponge filter is the safest filtration choice.

Common Questions
Blue Rili Shrimp FAQ
Are Blue Rili Shrimp good for beginners?+
Yes. Blue Rili Shrimp are Neocaridina — among the most beginner-friendly invertebrates in the hobby. They tolerate a wide pH range, breed readily in stable conditions, and are active and visible throughout the day.
How are Blue Rili Shrimp shipped?+
Professionally packed in an insulated box with a heat or cold pack matched to your local weather forecast. Livestock ships Monday through Thursday and delivers Tuesday through Friday. Choose your preferred delivery date at checkout.
How do I acclimate Blue Rili Shrimp?+
Drip acclimate: empty the bag into a small container and drip tank water in at 2–3 drops per second for 1–3 hours. Net the shrimp into the tank — never add bag water to your aquarium. Dim the lights for the first hour.
Can Blue Rili Shrimp live with fish?+
Yes, with the right species. Ember Tetras, Pygmy Corydoras, Otocinclus, and Celestial Pearl Danios are all safe choices. Avoid any fish large enough to swallow a shrimp. Dense planting provides cover for shrimplets.
What water parameters do Blue Rili Shrimp need?+
pH 6.5–8.0, temperature 65–80°F, GH 6–8, KH 2–4. Most conditioned tap water works well. Avoid copper-based medications and sudden parameter swings.
What is the free shipping threshold?+
Free 2-Day Shipping on orders $120+. Free Overnight on orders $200+. Plants and dry goods ship free at $75+.
Is there a live arrival guarantee?+
Yes — 100% Live Arrival Guarantee on every order. Photo any DOA in the sealed bag on the day of delivery. Contact us through the Start a Claim page and we will resolve it.
Will all my Blue Rili offspring look the same?+
Not necessarily — Rili patterning has some genetic variation, so offspring may show slightly different pattern expressions. This is normal and part of what makes Rili colonies visually interesting over time.
Live plants give shrimp constant grazing surfaces, sheltered hiding spots for shrimplets, and promote the natural biofilm growth shrimp feed on. Every plant is shrimp-safe and ships safely alongside livestock.
