Crystal Red Shrimp (Caridina cf. cantonensis) are one of the most popular and visually striking freshwater shrimp species among aquarists. Known for their vibrant red-and-white coloration, these dwarf freshwater shrimp bring a stunning splash of color and delicate movement to planted aquariums and nano tanks. Their small size, usually around 1–1.5 inches as adults, makes them perfect for community tanks with other small, peaceful species.

These shrimp are peaceful and social creatures that thrive in groups. Keeping them in colonies enhances their natural behavior and increases breeding success, as they are prolific breeders under the right conditions. They enjoy heavily planted tanks with mosses, fine-leaved plants, driftwood, and rocks, which provide hiding spots, grazing surfaces, and security.

Water quality is critical for Crystal Red Shrimp. They prefer clean, soft, slightly acidic water with stable parameters. Regular water changes, gentle filtration, and careful monitoring of water chemistry are essential to maintain their health and vibrant coloration. Sudden changes in water parameters can stress them and affect their survival.

Crystal Red Shrimp are omnivorous and primarily feed on biofilm, algae, and detritus in the aquarium. Their diet can be supplemented with high-quality shrimp pellets, blanched vegetables like zucchini or spinach, and occasional protein-rich foods to support growth and reproduction. Providing a varied diet helps maintain their bright red and white patterns.

These shrimp are a favorite for aquarists who enjoy breeding and creating thriving shrimp colonies. They are peaceful, fascinating to watch, and contribute to the overall cleanliness of the tank by consuming algae and leftover food. With proper care, Crystal Red Shrimp can live up to 1.5–2 years and will reward hobbyists with vibrant color, interesting behaviors, and the potential for a thriving, expanding colony.
