Aura blue shrimp are a selectively bred ornamental dwarf shrimp prized for their electric blue coloration and active temperament. These freshwater crustaceans have become a standout choice for planted tanks and nano aquariums because of their vivid appearance and reef-safe compatibility with aquascaped hardscapes.
Beyond their striking looks, aura blue shrimp are an efficient clean-up crew, grazing on biofilm, detritus, and soft algae while contributing to stable water chemistry. Their small bioload and engaging behavior make them suitable for both experienced breeders and newcomers dedicated to high-standard husbandry.

Optimal Tank Conditions for Aura Blue Shrimp
Stable water parameters are more important than chasing extreme values when keeping aura blue shrimp. Aim for consistent temperature, steady pH, and gentle current to reduce stress and encourage natural foraging behavior. Frequent small water changes are more effective than occasional large ones.
Use an appropriately sized filter with a gentle flow setting, and add sponge pre-filter guards to protect juvenile shrimp from being drawn into the intake. Provide dark substrate such as sand or fine gravel to intensify their blue coloration and offer plenty of hiding spots using rocks, botanical leaf litter, and moss pads.
Nutrition and Feeding Strategies
In a mature planted tank, aura blue shrimp will graze on biofilm and algae, but supplemental feeding supports vibrant coloration and colony growth. Offer a mix of high-quality shrimp pellets, powdered spirulina, and occasional blanched vegetables to cover essential vitamins and minerals.
Feed in small quantities once or twice daily, removing any uneaten food within a few hours to prevent water quality decline. Observing feeding response times helps you fine rations and detect early signs of stress or illness within the colony.
Breeding and Colony Management
Successful breeding hinges on water stability, ample hiding places for berried females, and a balanced biofilm matrix on surfaces for larval development. Maintain slightly harder water within the normal range for this species to improve hatching success and molt cycles.
Separate nursery areas using moss carpets or breeder boxes to safeguard young shrimp, and avoid medications containing copper or heavy metals that can be lethal to crustaceans. Selective breeding for intensity of blue coloration can be pursued over generations once the colony is stable.
Key Takeaways for Long-Term Success
- Maintain stable temperature, pH, and general hardness within recommended ranges.
- Use gentle filtration and provide plenty of biological filtration media.
- Offer a varied diet that supports coloration and overall health.
- Create a planted setup with dark substrate and hiding spots to reduce stress.
- Monitor colony growth and cull selectively to sustain vibrant traits over generations.
FAQ
Reader questions
How can I make the blue coloration of my aura shrimp more vivid?
Provide a dark substrate, stable water parameters, and a diet rich in carotenoids from high-quality commercial shrimp foods or occasional spirulina supplements. Minimize stress by avoiding sudden changes in light, temperature, or water chemistry.
What size tank is suitable for a small colony of aura blue shrimp?
A 10 to 20 liter planted tank can support a small colony comfortably, provided filtration is gentle, bioload is light, and ample hiding spots and grazing surfaces are available. Avoid overcrowding to prevent stress and water quality issues.
Are aura blue shrimp compatible with small fish species?
They can coexist with very small, peaceful fish that do not prey on shrimp. However, the safest approach is to house them with non-predatory invertebrates or in species-only setups to ensure colony protection and uninterrupted breeding cycles.
What are the first signs of illness in aura blue shrimp?
Look for reduced activity, loss of color, erratic swimming, or visible lesions. Molting problems, fungal growth on appendages, or sudden population decline can indicate poor water quality, inadequate nutrition, or disease exposure requiring prompt intervention.
