What Do Blue Red Rili Shrimp Look Like?
Blue Red Rili Shrimp, often called Blue Razz Shrimp, typically display red sections or patches over a blue to bluish-translucent body. The exact balance of blue, red, and clear coloration can vary considerably between individuals.
Age, sex, genetics, lighting, substrate, aquarium background, and individual lineage can all affect how strong the colors appear.
Important Genetics Note: This line may not breed true with complete consistency. Offspring can vary in the amount, tone, and placement of blue and red coloration. Hobbyists breeding specifically for this look should expect to selectively retain the offspring that best match their preferred pattern and color intensity.
Blue Red Rili Shrimp Water Parameters
Blue Red Rili Shrimp are Neocaridina and generally perform best when water chemistry stays stable rather than being constantly adjusted. The ranges below reflect our Neocaridina systems.
| Parameter | Our Tank Range |
|---|---|
| pH | 7.0–7.8 |
| GH | 7–8 |
| KH | 3–4 |
| TDS | 200–250 ppm |
| Temperature | 65–74°F |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
Avoid sudden changes in temperature, pH, hardness, or TDS. A fully cycled aquarium with mature biological filtration and consistent maintenance matters more than chasing one exact number.
For more detail, read our Neocaridina Shrimp Water Parameters Guide.
Best Tank Setup for Blue Red Rili Shrimp
Mature, Cycled Aquarium
Blue Red Rili Shrimp should be introduced to a fully cycled aquarium with stable water quality. Mature tanks also provide more biofilm and microorganisms for constant grazing.
Plants, Moss & Hardscape
Plants, moss, wood, leaves, and aquarium-safe rock increase grazing area and provide cover during molts. Dense moss is especially useful for newborn shrimplets. Browse our live aquarium plants for shrimp-friendly setups.
Gentle Filtration
Sponge filters are ideal for many shrimp tanks because they provide gentle water movement, biological filtration, and extra grazing surface without exposing baby shrimp to an unprotected intake.
What Do Blue Red Rili Shrimp Eat?
Blue Red Rili Shrimp spend much of the day grazing biofilm, microorganisms, soft algae films, decaying organic material, and small food particles. Supplemental feeding becomes especially useful in cleaner aquariums or larger colonies.
| Food Source | Role in the Aquarium |
|---|---|
| Biofilm | Important natural grazing source in mature tanks |
| Soft algae films | Frequently grazed from hardscape, plants, and glass |
| Shrimp foods / wafers | Useful supplemental nutrition for established colonies |
| Botanicals / leaves | Add grazing surface and slowly decomposing organic material |
| Blanched vegetables | Optional occasional supplemental food |
Feed conservatively and remove excess food before it begins to affect water quality. Browse our shrimp food and botanicals for supplemental feeding options.
Breeding Blue Red Rili Shrimp
Blue Red Rili Shrimp reproduce completely in freshwater. Mature females carry fertilized eggs beneath the abdomen until fully formed baby shrimp hatch directly into the aquarium.
Because this color line can produce variable offspring, breeding for a consistent Blue Razz appearance may require ongoing selection. If your goal is to strengthen the line, keep the colony separate from other Neocaridina colors and selectively retain offspring with the blue-and-red combination you prefer.
Breeder Pack: Our Blue Red Rili Breeder Pack includes 10 breeding-age shrimp with approximately 7 females and 3 males, providing a female-heavy starting ratio for hobbyists focused on establishing a colony.
For general breeding fundamentals, read our Neocaridina Shrimp Breeding Guide.
Blue Red Rili Shrimp vs. Red Rili Shrimp
| Trait | Blue Red Rili / Blue Razz | Red Rili Shrimp |
|---|---|---|
| Typical appearance | Red patterning with blue to bluish-translucent coloration | Red sections separated by translucent or clear areas |
| Species type | Neocaridina | Neocaridina |
| Care level | Beginner-friendly | Beginner-friendly |
| Freshwater breeding | Yes | Yes |
| Color-line consistency | Can produce variable offspring | Generally selected around the established red-and-clear Rili pattern |
If you prefer the classic red-and-clear pattern, view our Red Rili Shrimp.
Can Blue Red Rili Shrimp Live With Other Neocaridina?
Different Neocaridina color lines can generally live together peacefully, but they can interbreed. Mixing colors will make offspring less predictable and can make it harder to maintain the Blue Red Rili appearance over future generations.
If your goal is selective breeding for the Blue Razz pattern, keep this colony separate from other Neocaridina morphs.
Blue Red Rili Shrimp Tank Mates
Blue Red Rili Shrimp are peaceful. Snails and other non-aggressive invertebrates are commonly compatible, while some small peaceful fish can work in heavily planted tanks. However, nearly any fish may eat baby shrimp if shrimplets are small enough to fit in its mouth.
For maximum breeding success and shrimplet survival, a dedicated shrimp tank is the safest option.

Blue Red Rili Shrimp FAQ
Are Blue Red Rili Shrimp the same as Blue Razz Shrimp?
Yes. Blue Razz is another hobby name used for this blue-and-red patterned Neocaridina line.
Are Blue Red Rili Shrimp Neocaridina?
Yes. They are a Neocaridina color line and share the same general freshwater care requirements as other Neocaridina shrimp.
How big are Blue Red Rili Shrimp when shipped?
Our Blue Red Rili Shrimp are approximately 1/2 to 1 inch and are sold at breeding age.
Are Blue Red Rili Shrimp good for beginners?
Yes. Their basic care is beginner-friendly when they are kept in a mature, fully cycled aquarium with stable water chemistry.
What water parameters do Blue Red Rili Shrimp need?
Our Neocaridina systems run around pH 7.0–7.8, GH 7–8, KH 3–4, TDS 200–250 ppm, and 65–74°F. Stability matters more than chasing exact values.
Will Blue Red Rili Shrimp breed in freshwater?
Yes. Their entire reproductive cycle occurs in freshwater, and mature females carry eggs until fully formed shrimplets hatch.
Do Blue Red Rili Shrimp breed true?
Not always. This line can produce offspring with noticeable variation in red, blue, and translucent coloration, so selective breeding may be needed to maintain a preferred Blue Razz look.
What comes in the Blue Red Rili Breeder Pack?
The Breeder Pack includes 10 breeding-age shrimp with approximately 7 females and 3 males.
What is the difference between Blue Red Rili and Red Rili Shrimp?
Blue Red Rili Shrimp combine red patterning with blue to bluish-translucent coloration, while classic Red Rili Shrimp are primarily red and clear.
Can Blue Red Rili Shrimp live with other Neocaridina?
Yes, but they can interbreed with other Neocaridina color lines. Keep them separate if maintaining or refining the Blue Razz pattern is important.
Can Blue Red Rili Shrimp live with fish?
They can live with some small peaceful fish, but fish may prey on newborn shrimplets. A dedicated shrimp tank gives the best breeding and survival rates.
Do Blue Red Rili Shrimp eat algae?
They graze on soft algae films and biofilm, but they are not a complete algae-control solution. Proper lighting, nutrient management, filtration, and maintenance still matter.
Do Blue Red Rili Shrimp need a heater or filter?
A heater is not always necessary if room temperature remains consistently suitable. A mature biological filter is strongly recommended, with sponge filtration being especially shrimp-friendly.

Overall rating: 4.8 / 5 from 103 reviews.
They look like basic red rili, there wasn’t much of a blue hue to them. Big and healthy though
SURPRISE!! I hadn't ordered a Blue Raz but I got two!! Im so happy because I was planning on breeding these and now I have a head start!! Thank you Shrimp-up! You're really the best supplier! 🩵🫧🍓🫐
So far, so good! They moved into their new home yesterday after quarantine. I lost two, but the rest of my Blue Razz shrimp are doing great.
First off, I was totally stoked to see that you sent eight of them instead of five but 4 of them died within a few days even though I did a drip acclimation over a 3 hour period. My parameters are good on my tank, temp is steady 74, ammonia is 0, nitrites- 0 ppm and nitrates are 15 ppm and the tank was fully cycled for 2 months prior to adding them. I haven’t seen them really take on that blue yet and still seems to be red and white still. Hopefully they will settle in more sooner and show that blue too.
They were shipped faster than I expected! They look healthy and I am super pleased! Like others have shared, the blue is not very vibrant like the picture. I will be purchasing again, thank you for the good first experience!
Shrimp are beautiful arrived very fast and seem to be quite healthy!
They’re so cute
Overall these shrimp are really nice and they seem healthy. I am pleased with them and would likely order again, however there is an issue with coloring. Cons: Blue is not very vibrant. If you are expecting your shrimp to be vibrant blue and red like the picture, you are likely to be disappointed. I ordered a breeder pack, and received 8 red and blue rilis, one regular red rili, and one blue shrimp. The red blue rilis are vibrant red, but the blue is washed out to the point that I can't see it when they are in my aquarium. That is with an RGB full spectrum light. I waited 3 weeks to see if they would adjust and color up as they got more comfortable. They are out and about often now, but don't seem any more blue than before. Pros: They seem very healthy. A different shrimp order in this same package had a DOA, but all the cherry shrimp were healthy and the other shrimp did not seem stressed. I had two cherry shrimp die after drip acclimating them for several hours. I expected one or two shrimp to die as they were shipped across the country and the water parameters are likely to be very different. Also, one of the deaths was my fault, as the shrimp jumped out of my net into cold water and I could not get it back out right way. I'm pretty sure it died of cold shock later that night. The other shrimp looked like a failed molt a few days later. I decided to hold off on reaching out about the deaths and miscolored shrimp as I was overall pleased with the numbers and I received two berried females and wanted to see how that would pan out. I can say that as of today I have at least 10 baby rili shrimp the size of a grain of rice, so the females were healthy enough to withstand the shipping and adjustment phase while carrying eggs.
Two were dead but i expected as much , love how colorful the ones I have are
Came alive and thriving super happy with them I will say they don’t look exactly like the picture their lacking the blue in them, instead their clear where the blue was supposed to be but still super cute and I’m in love
Great experience! Everything arrived as described and communication was smooth. Would buy again
I was nervous to get the shrimp delivered from Michigan to Arizona but they arrived in great shape, along with 3 extra shrimp! I had a question for customer support and was responded to promptly. Will be using again 🫡
6 stars if I could! I ordered the breeders pack expecting only 10 shrimp, as it's advertised. I ended up receiving 14 alongside my 2 Pom Pom crabs. All arrived alive from Michigan to California with great packaging protecting them. 2 however were not the same color, one was translucent as another one was fully red, but that left me with 12 of the Blue razz shrimps, more than I was expecting and bought. would definitely buy from here again!
Love them!
Everything came out great. Shrimp are thriving.
Should have bought more pretty sure they are all dead now. It has been a few eeeks
I got sent a batch of the breeding pack blue razz and unfortunately due to inclement weather only four of them made it to Oregon alive, but within a week the proprietor made everything right and he picked me out some of the most vibrant bluish looking shrimp you could find including some excellent females and replaced the six shrimp within three days of getting my message. I'm pleased just punch and I couldn't recommend this establishment more!
Absolutely gorgeous and active! I will buy again!
Loved these lil guys being so active in my tank!!
All shrimp arrived healthy and safe!
Everything was exceptional. Love the shrimp I received, and the customer service throughout was great. Definitely plan on using shrimp up aquatics again!
all of my shrimp arrived alive, well, & gorgeous! :)
Very happy with the speed if delivery, they also sent 2 extra incase of DOA which I didn't experience and I live in S Florida. They're all seem healthy. Would rate 5 stars if even just 1 shrimp had coloration like the pictures shown online. Most are very dull colored with no noticeable blue. Now I know what to expect next time..but I will buy from them again 👍
The shrimps arrived in perfect health and packaging. Just drip acclimated them to my tank. And now there is happy as can be and they even received one with some more shrimps on the way could not be happier.
The nightmare happened to me, my shrimp were severely delayed in transit. Absolutely no fault of the shop, responsive in emails, and incredibly hardy little shrimp! I'm talking well over a week delay in transit and they're perfect. All alive, even one more than I ordered. Cannot rave enough, fantastic shrimp!
Look healthy and happy!
This is my first time ordering definitely will order more later on! They are really unique and small
He's tiny but cute. I also got 8 Galaxy Rasboras (received 12, I think lol), 8 Chili Rasbora's (1 arrived dead, one is about to die, but with those two I only count 7?), 20 Skittles Pack (too many to try and count, 1 orange was dead on arrival and one is floating on it's back in the tank), 1 Green Rili Shrimp, 1 Green Jade Shrimp (which I haven't found yet), and 1 Blue Red Rili Shrimp (received 2). I will say that I got a huge Blue Shrimp which my son was super pleased with lol. Colors are very light, I almost couldn't tell they were Blue Red Rili. But I am sure they will darken up once they've settled in.
So fun looking! Great addition to the clan
Ordered 5 got 6! One did arrive dead(did not count in final number) but no worries here!
Love the shrimp. In the picture the blue looks white but the colors on all the shrimp are so vibrant.
These shrimp arrive all healthy and happy.They are very active, I wish you could see how beautiful but I have the brown water from my driftwood.I can't wait to order more.I even got a bonus surprise there had babies.Yippy Best hardy shrimp i have ordered. Thank you for my beautiful shrimp
These and panda shrimp are my new buys from this company and there the perfect color.They look just like the pictures.Lol on payday I'm ordering more,maybe I get lucky and have babies.Well can't say enough on how great the quality of shrimp they are
They arrived a day later than expected but all of them were alive and well, and looking great in their new home... ill definitely be ordering from here again.
We ordered these guys hoping for a bit more depth to their color but still love them! They arrived healthy and were honestly larger than expected so that was a nice surprise.
Lovely healthy shrimp arrived promptly and safely, now happily adjusted to its new home.
All my shrimp got here healthy and they look good. I will say that they are not anywhere close to the coloring showed in the photo. They have a slight blue tent but they’re basically red rilli, not really worth the extra 5 or so bucks for pretty much the same shrimp. I’m happy I have them and they are pretty, but they are kinda falsely advertised lol
I received all my shrimp alive and well. Very great seller 10/10 would order again!
Shrimp Up Aquatics is my go to every time I get new shrimp. They have a great inventory of very happy, beautiful, healthy, swimmy shrimp with excellent genetics. Their staff is also very friendly, knowledgeable, and quick to respond. Highly recommend!!
