Bring a thriving piece of Hawaii's unique aquatic ecosystem into your home with a colony of 25 Opae Ula (Halocaridina rubra), also known as Hawaiian Volcano Red Shrimp. Native to Hawaii's anchialine pools, these remarkable shrimp are celebrated for their vibrant red coloration, exceptional hardiness, and impressive lifespan that can exceed 20 years under proper conditions.

A colony of 25 shrimp provides a larger and more active population, making it easier to observe natural behaviors, social interactions, and breeding activity. Whether you're establishing a self-sustaining ecosystem jar, expanding an existing colony, or creating a dedicated brackish water habitat, these shrimp offer a fascinating and low-maintenance aquatic experience.

Unlike many aquarium species that require frequent care, Opae Ula thrive in stable environments with minimal intervention. Their ability to graze on naturally occurring algae and biofilm makes them an ideal choice for hobbyists seeking a beautiful and sustainable ecosystem.

Healthy Colony of 25 Shrimp – A larger starter population creates a more active and visually engaging ecosystem.

Exceptional Lifespan – Opae Ula shrimp are known to live for 20 years or more when kept in stable conditions.

Low-Maintenance Care – Requires minimal feeding and very little ongoing maintenance compared to traditional aquarium pets.

Ideal for Self-Sustaining Ecosystems – Thrives in balanced brackish water habitats where natural algae and biofilm develop.

Natural Breeding Potential – A colony of 25 provides excellent opportunities to observe natural reproduction and colony growth.

Perfect for Beginners & Enthusiasts – Easy to care for while offering a fascinating glimpse into Hawaii's unique aquatic ecosystems.

In the volcanic landscapes of Hawaii, Opae Ula shrimp have evolved to survive in isolated anchialine pools where fresh and saltwater naturally mix. These unique environments remain remarkably stable, allowing the shrimp to thrive for many years with very little outside intervention.

A colony of 25 shrimp offers a more dynamic ecosystem experience. Their increased numbers create greater activity throughout the habitat while providing a stronger foundation for long-term colony growth. As they explore, graze, and interact within their environment, you'll gain a deeper appreciation for one of nature's most resilient aquatic species.

For hobbyists seeking a self-sustaining ecosystem that combines beauty, simplicity, and longevity, Opae Ula shrimp are truly one of the most rewarding aquatic pets available.

Setting Up Your Habitat

1. Prepare a brackish water environment using a quality marine mineral mix.
   
2. Allow the habitat to stabilize before introducing the shrimp.
   
3. Acclimate the shrimp gradually to their new water conditions.
   
4. Place the ecosystem in a location with indirect natural or ambient light.
   
5. Avoid overfeeding, as Opae Ula primarily graze on algae and biofilm.

Ongoing Care

• Maintain stable salinity levels.
  
• Avoid sudden temperature changes.
  
• Do not use copper-based medications.
  
• Perform minimal maintenance to preserve ecosystem balance.
  
• Monitor for healthy activity and natural grazing behavior.

Ideal Conditions

• Brackish water habitat
  
• Stable room temperature
