50 Opae Ula | Halocaridina rubra | Volcano Red Shrimp

Create a vibrant and thriving Hawaiian shrimp ecosystem with a colony of 50 Opae Ula (Halocaridina rubra), also known as Volcano Red Shrimp. Native to Hawaii's unique anchialine pools, these remarkable shrimp are prized for their brilliant red coloration, incredible longevity, and ability to flourish in low-maintenance brackish water environments.

A colony of 50 shrimp offers an impressive display of natural activity, making it easier to observe social interactions, grazing behavior, and colony development. Whether you're establishing a large ecosystem jar, stocking a dedicated Opae Ula aquarium, or expanding an existing habitat, this larger colony provides an excellent foundation for long-term success.

Unlike many aquatic pets, Opae Ula require minimal intervention and can thrive for decades in stable conditions. Their hardy nature and ability to live in self-sustaining ecosystems make them a favorite among both beginner and experienced hobbyists seeking a unique and rewarding aquatic experience.

Includes 50 Healthy Opae Ula Shrimp – Establish a thriving colony with a substantial starting population.

Supports Natural Colony Growth – Larger numbers increase opportunities for breeding and long-term population development.

Low-Maintenance Aquatic Pet – Requires minimal feeding and routine care once established.

Perfect for Self-Sustaining Ecosystems – Thrives in balanced brackish water habitats with naturally occurring algae and biofilm.

Long Lifespan – Can live for 20 years or more when maintained in stable environmental conditions.

Active and Engaging Display – Enjoy increased visibility and activity throughout your ecosystem or aquarium.

For centuries, Opae Ula shrimp have inhabited Hawaii's secluded anchialine pools—rare aquatic environments where freshwater and seawater naturally mix. These isolated habitats have shaped one of the most resilient shrimp species in the world, allowing them to thrive with minimal resources and remarkable stability.

A colony of 50 Volcano Red Shrimp creates a dynamic ecosystem experience that closely mirrors their natural environment. Their larger population encourages natural behaviors, greater activity levels, and increased opportunities to witness colony growth over time.

Whether you're building a showcase ecosystem or establishing a long-term breeding colony, these shrimp offer a captivating connection to Hawaii's extraordinary aquatic world while requiring surprisingly little maintenance.
