Caridina Shrimp

Crystal Red (CRS) Shrimp

The iconic red-and-white banded Bee shrimp Caridina -- a foundational collector line whose graded pattern of vivid red and clean white has defined the Caridina hobby for decades.

Classic Red and White Banded Pattern Graded SS to SSS Available Foundational Caridina Collector Line Soft Acidic Water Required Intermediate Caridina Breeds in Freshwater

Crystal Red Shrimp (CRS) are the original and most iconic graded Bee shrimp Caridina -- the red-and-white banded line whose combination of vivid red sections and clean white banding launched the modern Caridina collector hobby and established the grading system that all subsequent Bee shrimp lines use. The grading reflects coverage, band definition, colour opacity, and white coverage proportion: lower grades carry more red and narrower white bands; higher grades (SS, SSS) carry more white coverage, bolder and more precisely defined banding, and deeper, more opaque red in the coloured sections. At the highest grades, the red sections are fully opaque and the white sections are bright and clearly defined with sharp edges -- the pattern reads as a high-contrast, graphic alternation of vivid red and clean white that is among the most immediately striking patterns available in the freshwater hobby. Crystal Red and Crystal Black are genetically compatible and are sometimes kept together for visual diversity. Care requires soft, acidic, low-KH water maintained with RO remineralisation and active aquasoil. Safe with all snails.

Pattern, Grade and Behaviour

Vivid red and clean white banding -- the original collector Caridina pattern -- the CRS pattern at its best carries a fully opaque, vivid red in the coloured sections and clean, bright white in the banded sections, with clearly defined edges between the two colour zones. The grading system reflects the completeness of this expression: lower grades have more red coverage, narrower white bands, and less distinct edges; higher grades have more white coverage, bolder bands, and sharper colour boundaries. Grade reflects white coverage, band definition, and colour opacity -- the visual difference between grades is significant and immediately apparent when specimens are viewed side by side. SS and SSS grade animals carry a visually striking, high-contrast pattern; lower grades carry the same genetic foundation with progressively less complete pattern expression. Grade quality is visible at a glance on healthy adults in optimal conditions. Colour is parameter-responsive -- optimal conditions produce the most vivid pattern -- the vivid red and clean white reach their most saturated, most clearly defined expression at the optimal end of the parameter range: pH 6.0-6.5, GH 4-5, KH 0-1, temperature 70-72F. Parameters toward the outer edge of the survivable range produce less vivid red and less bright white than animals in genuinely optimal conditions. The foundational collector Caridina -- extensively documented and well understood -- CRS have been kept and bred in the hobby for longer than any other graded Caridina line. The accumulated knowledge, documentation, and community experience available for CRS care is more extensive than for any other Caridina species -- a meaningful practical advantage for keepers moving from Neocaridina to their first Caridina. Intermediate Caridina difficulty -- the most well-supported starting point for Caridina -- the combination of extensive documentation, well-understood care requirements, and predictable behaviour in well-maintained tanks makes CRS the most practical entry point into Caridina keeping for experienced Neocaridina keepers ready to move to soft, acidic water management. Breeds in freshwater with direct shrimplet release -- females carry clutches for 4-6 weeks and release fully formed miniature CRS into the tank. Dense moss, established biofilm, and parameter stability throughout the brooding period support shrimplet survival.

Getting Started

1Establish soft acidic parameters for two weeks before introduction -- pH 6.0-6.5, GH 4-5, KH 0-2, temperature 70-73F using RO water remineralised with Caridina-specific mineral. Active aquasoil maintains stable low pH. Test daily to confirm stability before introduction.
2Drip acclimate over 60-90 minutes -- float bag for 15 minutes, then drip at one drop per second for 60-90 minutes.
3Dense moss and established biofilm before shrimp arrive -- Java Moss, Christmas Moss, or Taiwan Moss provides biofilm and shrimplet shelter for the first breeding generation.
4Feed sparingly and remove uneaten food within 2-3 hours -- small amounts of high-quality Caridina food every 1-2 days. Consistent removal of uneaten food is important in the low-buffering CRS environment.
Bonus Tip

Crystal Red alongside Crystal Black shrimp in the same tank is the most classic Caridina combination in the hobby -- the two lines share identical care requirements, coexist without conflict, and produce offspring carrying both red-and-white and black-and-white pattern expressions alongside mixed intermediates. The combined colony of vivid red-and-white and deep black-and-white Bee shrimp in a single tank is visually striking in a way that either line alone is not, and the gradual colour diversity that develops across successive mixed-generation offspring adds continued visual interest as the colony matures.

Policies & Disclaimers

What to expect from your shrimp, how our guarantee works, and what to do when your order arrives.

Size

¼–½ inch

We select this size because younger shrimp generally tolerate shipping and adjust to a new aquarium better than fully grown adults. Proper acclimation and stable water conditions remain essential.

Photos & appearance

Product photos show representative examples of the shrimp’s variety and appearance. They do not show the exact animals you will receive or guarantee an identical color, pattern or intensity.

Individual appearance can vary with age, sex, lighting, substrate, aquarium conditions and shipping stress. Shrimp may arrive with lighter coloration and develop fuller color as they settle and mature.

Photos may show mature individuals. Please use the stated size and pack details to understand what you are purchasing.

Grades & selection

Unless a listing explicitly states a grade or selection standard, such as “S Grade” or “Painted Fire Red,” shrimp are sold as mixed grade. When specified, that listing’s grade or selection standard applies.

Even within the same grade, color coverage, intensity and pattern naturally vary. Individual shrimp are not guaranteed to look identical to the product photos.

Natural differences between males and females also apply to S Grade selections. Males may be smaller and less intensely colored than females of the same variety, including within an S Grade selection. This difference alone does not mean a male is incorrectly graded.

Natural variation alone is not considered a DOA claim. If you believe you received the wrong variety or a product that does not match its stated grade, contact us with clear photos so we can review it.

Males & sex selection

Male shrimp may be smaller and less intensely colored than females of the same variety. This difference alone does not indicate poor health or an incorrect grade. This also applies to S Grade selections; selecting a grade does not guarantee female-like size or color intensity in males.

Unless the listing explicitly promises a particular sex or ratio, individual males, females and sex ratios are not guaranteed.

Breeder packs

Breeder packs include a minimum of 8 females and 2 males. Bonus shrimp are random scoops and are not selected by sex, so your pack may contain more than 2 males when bonuses are included.

A breeder pack does not guarantee adult size, berried (egg-carrying) females, immediate breeding or a particular number of offspring.

Breeding results depend on maturity, acclimation and aquarium conditions.

What to expect after shipping

Temporary faded color, hiding, reduced activity and reduced appetite can occur after shipping. Provide a stable, established aquarium with appropriate conditions and follow proper acclimation practices.

Shipping stress alone is not a confirmed DOA. Our guarantee covers confirmed losses on arrival under its stated conditions; losses after the two-hour claim window are not covered.

Bonus shrimp & your paid count

When inventory allows, we may include one bonus animal for every five ordered of the same species. Bonuses are discretionary, are not guaranteed and are not separately eligible for refund or replacement.

Bonus shrimp are random scoops, not sex-selected. They may be male or female and can change the overall sex ratio of a breeder pack, including bringing the total above 2 males.

Bonus animals count toward the total arriving alive. Guarantee coverage applies when live arrivals fall below the number you paid for.

Example: If you pay for 10 shrimp and receive 12, an arrival of 11 live shrimp still fulfills your paid count. If fewer than 10 arrive alive, the shortfall may qualify under the guarantee.

For a suspected short count, document the animals, empty bag and shipping label before introducing shrimp to your aquarium. Refer to the full policy for the required counting photos.

Molting, shelter & handling

Shrimp shed their exoskeleton as they grow. A transparent, empty molt can resemble a shrimp; finding one does not by itself mean an animal has died. Provide grazing surfaces and shelter so freshly molted shrimp can remain undisturbed.

Avoid handling delicate shrimp to check their color or sex. If an animal appears injured, trapped in a molt or dead on arrival, photograph its condition through the unopened bag and report the concern promptly. Care observations do not replace the guarantee’s claim evidence.

Choosing tankmates & maintaining color lines

Small shrimp and shrimplets can be eaten by fish, even when adult shrimp appear to coexist with them. Dense plants and hiding spaces reduce exposure but cannot guarantee survival with predators. Review the particular shrimp’s water requirements alongside those of any tankmates.

Different Neocaridina color lines can interbreed, and offspring may not retain the parent colors. A mixed-color display and a breeding project with a consistent color line have different goals. A shrimp’s appearance at purchase does not guarantee the appearance of future offspring.

Acclimation & ongoing care

Prepare a stable, established aquarium before delivery. Use the acclimation guidance appropriate to the species and compare your measured water conditions with its published requirements rather than changing water rapidly to chase a single number.

Inspect and document any arrival concern before transferring animals, following the full guarantee’s documentation rules. Ongoing feeding, water quality and breeding outcomes depend on aquarium conditions; the Live Arrival Guarantee is an arrival policy, not a promise of future breeding or lifespan.

Checking quantities & reporting a short count

Check the actual animals received against your paid order quantity. For a suspected short count, the full policy calls for a clear counting photo showing all animals, the empty bag and the shipping label before they are introduced into an aquarium. Follow its counting instructions and contact us if you cannot document the count clearly.

Verified miscount claims are resolved with a refund for the missing paid animals under the current policy. A count made after release can be unreliable when animals hide among plants or hardscape.

Before opening: photographs & your first report

Use the email address on the original order and include all arrival concerns in the initial message to support@superiorshrimpaquatics.com within two hours of the carrier’s recorded delivery time. Photograph the sealed bag, visible and countable animals, shipping label, box and packing materials.

If the bag is leaking or damaged, photograph the leak or damage and wet packing before opening. Keep the original photographs and packaging. For cloudy water that prevents counting, take the original cloudy-water photo first and follow the full policy’s specific additional clear-container documentation instructions.

The guarantee contains restrictions on opening bags, acclimation and transfers. Review those instructions before taking action so the evidence needed to assess the claim is preserved.

Arrival problem? Document it promptly.

Email support@superiorshrimpaquatics.com within two hours of the carrier’s recorded delivery time, using the email address on your order.

  • Photograph the original sealed bag with the animals visible and countable.
  • Include the shipping label, outer box and packing materials.
  • Document any bag damage or leakage before opening.
  • Report all arrival losses in your initial message.

Read the full guarantee for photo requirements, cloudy-water documentation and claim eligibility before opening or transferring animals. Approved claims are resolved under the options and conditions stated there.

Shipping & coverage limits

Ground shipping carries increased risk for live animals, and the policy reserves the right to refuse guarantee claims on ground shipments. Choose your shipping method carefully.

The guarantee applies to the first delivery attempt. Redirection, pickup holds and carrier delays can affect eligibility under the full policy. Any product-specific coverage restrictions stated in a listing also apply.

Hitchhikers & quarantine

Live aquatic products can carry tiny hitchhikers or eggs despite inspection. Pest-free arrival is not guaranteed. We recommend quarantining new arrivals before introducing them into an established aquarium.

Returns

Care guidance in this tab does not create additional guarantee requirements or exclusions. Please read the full policies for complete eligibility, documentation, resolution and return requirements.
