Mixed Caridina Shrimp Mixed Caridina Shrimp are a colourful and fascinating addition to freshwater aquariums, offering a natural mix of attractive Caridina varieties in a single group. Known for their peaceful behaviour, small size and active grazing habits, these freshwater shrimp are ideal for planted aquariums and dedicated shrimp tanks. Mixed Caridina Shrimp can display a variety of colours and patterns, making every colony unique while providing valuable algae and biofilm grazing throughout the aquarium. Features of Mixed Caridina Shrimp Peaceful freshwater shrimp suitable for community and dedicated shrimp aquariums Typically reach approximately 2–3 cm in length Available in a diverse range of colours and patterns Excellent natural grazers of algae and biofilm Active throughout the aquarium, particularly on plants, wood and hardscape Best suited to mature aquariums with stable water parameters Can reproduce successfully when provided with suitable conditions The best aquarium size for Mixed Caridina Shrimp A minimum aquarium size of 20 litres is recommended for Mixed Caridina Shrimp, although larger aquariums offer greater water stability and space for colonies to establish. Provide plenty of mature surfaces for grazing and ensure the aquarium is fully cycled before introducing shrimp. Tank Mate Compatibility for Mixed Caridina Shrimp Mixed Caridina Shrimp are peaceful but small, making them vulnerable to predation by larger fish. A dedicated shrimp aquarium offers the best breeding results. Suitable peaceful tank mates include: Otocinclus Pygmy Corydoras Chili Rasbora Ember Tetra Celestial Pearl Danio Diet for Mixed Caridina Shrimp Feed a quality shrimp-specific food as the primary diet, supplemented with algae wafers, blanched vegetables and natural biofilm. Offer small portions and remove uneaten food to prevent water quality issues. Dried leaves can also provide a valuable natural grazing surface. Aquarium Setup Mixed Caridina Shrimp Aquarium Filtration Use gentle filtration with a sponge filter or pre-filtered intake to protect small shrimp and shrimplets. Strong biological filtration is important for maintaining stable water quality. Aquarium Plants Live plants, mosses and floating plants are highly recommended. They provide grazing surfaces, shelter and valuable cover for juvenile shrimp. Aquarium Lighting Moderate lighting is suitable and supports healthy plant and biofilm growth. Maintain a consistent lighting period to encourage a stable aquarium environment. Aquarium Heating Maintain a stable temperature of approximately 20–24°C and avoid sudden changes in temperature. Aquarium Substrate Use a fine, shrimp-safe substrate. Darker substrates can provide an attractive contrast against the varied colours of Mixed Caridina Shrimp. Aquarium Decorations Add driftwood, smooth rocks, moss and dried leaves to create additional grazing surfaces and hiding places. Dense plant growth and hardscape provide essential shelter, particularly for young shrimp.
