What Do Orange-Eye Royal Blue Tiger Shrimp Look Like?
These shrimp are selected for rich blue body coloration and distinctive orange eyes. Individual shrimp can vary in blue intensity, opacity, and pattern expression, with some appearing lighter or more translucent and others developing deeper royal-blue tones.
Genetics, age, sex, lighting, substrate, aquarium background, and overall condition can all influence how intense the coloration appears.
Orange-Eye Royal Blue Tiger Water Parameters
Orange-Eye Royal Blue Tiger Shrimp are Caridina and generally perform best in soft, stable water with very low carbonate hardness.
| Parameter | Recommended Range |
|---|---|
| pH | 6.2–6.9 |
| GH | 4–6 |
| KH | 0–2 |
| TDS | 90–120 ppm |
| Temperature | 68–74°F |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
Avoid sudden changes in pH, hardness, TDS, or temperature. Mature biological filtration and consistent water chemistry are more important than repeatedly adjusting the aquarium to chase one exact number.
Best Tank Setup for Orange-Eye Royal Blue Tiger Shrimp
Add OERBT shrimp only to a fully cycled, biologically mature aquarium. Mature systems provide stable filtration plus the biofilm and microorganisms shrimp graze on throughout the day.
Many Caridina keepers use remineralized RO or another controlled water source so GH, KH, and TDS remain predictable. Whatever source water you use, consistency is the priority.
Sponge filters work especially well for shrimp because they provide biological filtration, oxygenation, and extra grazing surface without exposing shrimplets to an unprotected intake.
Moss, wood, leaves, and live plants add cover and biofilm-rich grazing surfaces. Browse our live aquarium plants for shrimp-friendly setups.
What Do Orange-Eye Royal Blue Tiger Shrimp Eat?
These Caridina spend much of the day grazing biofilm, microorganisms, soft algae films, decaying organic matter, and tiny food particles.
| Food Source | Role in the Aquarium |
|---|---|
| Biofilm | Important natural grazing source in mature tanks |
| Soft algae films | Frequently grazed from plants, hardscape, 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 affects water quality. Browse our shrimp food and botanicals for supplemental feeding options.
Breeding Orange-Eye Royal Blue Tiger Shrimp
Orange-Eye Royal Blue Tiger Shrimp reproduce completely in freshwater. Mature females carry fertilized eggs beneath the abdomen until fully formed shrimplets hatch directly into the aquarium.
Color depth and pattern expression can vary among offspring, so hobbyists breeding toward a very dark royal-blue appearance may selectively retain shrimp that best match the desired phenotype.
For stronger breeding results, prioritize stable soft water, mature biofilm, gentle filtration, dense moss or cover, consistent feeding, and very low predation pressure.
Orange-Eye Royal Blue Tiger Shrimp vs. Blue Bolt Shrimp
| Trait | Orange-Eye Royal Blue Tiger | Blue Bolt Shrimp |
|---|---|---|
| Primary appearance | Deep royal blue body with vivid orange eyes | Icy blue to deeper blue coloration without orange eyes |
| Shrimp type | Caridina | Caridina |
| Care level | Intermediate | Intermediate |
| Freshwater breeding | Yes | Yes |
| Best choice for | High-contrast blue body and orange eyes | More uniformly blue-toned appearance |
If you prefer a blue Caridina without the orange-eye contrast, view our Blue Bolt Shrimp.
Can Orange-Eye Royal Blue Tiger Shrimp Live With Other Caridina?
Many Caridina varieties can share similar water conditions, but compatible Caridina lines may interbreed. If maintaining the royal-blue orange-eye line is important, keep the breeding colony separate from Caridina that may cross with it.
Orange-Eye Royal Blue Tiger Tank Mates
These shrimp are peaceful. Snails and other non-aggressive invertebrates are generally the safest companions. Some small peaceful fish may coexist with adults, but nearly any fish can prey on newly hatched shrimplets.
For maximum breeding success and shrimplet survival, a dedicated shrimp tank is the safest option.

Acclimating Orange-Eye Royal Blue Tiger Shrimp
Shipping water can differ from your aquarium in temperature, pH, GH, KH, and TDS. A gradual acclimation process helps reduce stress while the shrimp adjust to your system.
Follow our Freshwater Shrimp Acclimation Guide before releasing new livestock.

Orange-Eye Royal Blue Tiger Shrimp FAQ
Are Orange-Eye Royal Blue Tiger Shrimp Caridina?
Yes. Orange-Eye Royal Blue Tiger Shrimp are a Caridina line and have different water preferences from typical Neocaridina.
What does OERBT stand for?
OERBT is a common abbreviation for Orange-Eye Royal Blue Tiger Shrimp.
How big are they when shipped?
Our Orange-Eye Royal Blue Tiger Shrimp are approximately 1/2 to 1 inch and are sold at breeding age.
What color are Orange-Eye Royal Blue Tiger Shrimp?
They are selected for deep royal-blue body coloration paired with vivid orange eyes. Individual color intensity naturally varies.
What water parameters do they need?
Our recommended range is pH 6.2–6.9, GH 4–6, KH 0–2, TDS 90–120 ppm, and 68–74°F. Stable conditions are essential.
Do Orange-Eye Royal Blue Tiger Shrimp need soft water?
Yes. They generally perform best in soft water with very low KH compared with typical Neocaridina setups.
Can Orange-Eye Royal Blue Tiger Shrimp breed in freshwater?
Yes. Their entire reproductive cycle occurs in freshwater, and females carry eggs until fully formed shrimplets hatch.
Will all offspring be equally dark blue?
Not necessarily. Blue intensity and pattern expression can vary among offspring, so selective breeding may be used to emphasize darker royal-blue coloration.
What is the difference between Orange-Eye Royal Blue Tiger and Blue Bolt Shrimp?
Orange-Eye Royal Blue Tigers combine a deep blue body with vivid orange eyes, while Blue Bolt Shrimp are selected for an icy-to-deeper blue overall appearance without the signature orange-eye contrast.
Can they live with other Caridina?
Often yes when water requirements are compatible, but closely related Caridina may interbreed. Separate colonies are better if preserving the line matters.
Can they live with fish?
They can coexist with some small peaceful fish, but fish may prey on shrimplets. A dedicated shrimp tank gives the best breeding and survival rates.
Do they eat algae?
They graze on soft algae films and biofilm, but they are not a complete algae-control solution. Normal aquarium maintenance is still necessary.
Do they need a filter?
A mature biological filter is strongly recommended. Sponge filters are especially shrimp-friendly because they provide gentle filtration and extra grazing surface.
