The Ocean Blue Shrimp is a striking freshwater ornamental shrimp prized for its deep ocean-blue colouring, sparkling body and distinctive patterns. With shades ranging from rich navy and steel blue to pale blue and white, individual shrimp can display beautiful variations in colour and markings, making them a standout addition to a specialist shrimp aquarium.

This selectively bred Caridina variety is popular with shrimp enthusiasts who appreciate unusual colour forms and detailed close-up aquascapes. Its small size and peaceful nature make it ideal for a dedicated shrimp tank filled with mosses, aquatic plants, driftwood and natural grazing surfaces.

Ocean Blue Shrimp are more demanding than common Cherry Shrimp and are best suited to mature, fully cycled aquariums with soft, stable water conditions. A well-established environment encourages the growth of biofilm, which provides an important natural food source.

Behaviour and Aquarium Suitability

Ocean Blue Shrimp are peaceful, active invertebrates that spend their time grazing on biofilm, algae and tiny organic particles across plants, rocks and aquarium décor.

Provide plenty of moss, fine-leaved plants and crevices where shrimp can hide, particularly during moulting. A mature planted aquarium with stable parameters is essential, as sudden changes in water chemistry can be harmful.

They are best kept in a dedicated shrimp aquarium or with very small, peaceful tank mates that will not prey on adults or shrimplets. Avoid aggressive fish and any treatments containing copper unless specifically confirmed safe for shrimp.

Feeding and Nutrition

Ocean Blue Shrimp naturally graze throughout the day on biofilm, algae and decomposing plant material. Supplement this with a quality shrimp-specific food, algae-based pellets and occasional suitable foods such as blanched vegetables.

Feed small portions and remove uneaten food to prevent water-quality problems. In a mature aquarium, natural grazing can contribute substantially to their diet, so frequent heavy feeding is unnecessary.

Compatibility and Specific Care Requirements

Ocean Blue Shrimp thrive in a stable, mature aquarium with soft, slightly acidic water. Active shrimp soil, reverse-osmosis water remineralised with appropriate shrimp minerals, and reliable temperature control can help maintain the conditions they need.

Provide gentle filtration with a sponge pre-filter to protect tiny shrimplets, along with mosses and porous hardscape for grazing. Acclimate new arrivals slowly, particularly when their transport water differs from the aquarium's temperature or dissolved mineral content.

These shrimp can interbreed with compatible Caridina varieties, potentially affecting offspring colour and patterns. For predictable breeding results, keep them with compatible shrimp lines and avoid mixing them with unrelated colour varieties unless you are comfortable with mixed-colour offspring.

Frequently Asked Questions

1. How big do Ocean Blue Shrimp grow?

They typically reach around 2.5–3 cm as adults, making them suitable for compact, carefully maintained shrimp aquariums.

2. Are Ocean Blue Shrimp suitable for beginners?

They are better suited to aquarists with some shrimp-keeping experience because they require stable, soft water and a mature aquarium.

3. What do Ocean Blue Shrimp eat?

They graze on biofilm, algae and organic matter. Supplement their natural grazing with specialist shrimp foods and occasional plant-based treats.

4. Can Ocean Blue Shrimp live with fish?

They are safest in a dedicated shrimp aquarium. Very small, peaceful fish may coexist with adults, but many fish will eat shrimplets and some may prey on adult shrimp.

5. Can Ocean Blue Shrimp breed in an aquarium?

Yes. Females carry eggs beneath their abdomen until they hatch into miniature shrimp. A mature aquarium with abundant moss and biofilm improves the chances of young shrimp surviving.

6. Can Ocean Blue Shrimp live with Cherry Shrimp?

They can sometimes share an aquarium if their water requirements overlap, but they belong to different shrimp groups with different preferred conditions. For breeding and colour consistency, keeping them separately is recommended.

Common Mistakes

1. Adding shrimp to a newly established tank: Immature aquariums may lack stable conditions and sufficient biofilm.

2. Changing water parameters too quickly: Sudden shifts in temperature, pH or dissolved minerals can cause serious stress.

3. Using unsuitable tap water: Check hardness and TDS, and use appropriately remineralised water where necessary.

4. Overfeeding: Excess food decomposes and can quickly deteriorate water quality.

5. Keeping them with predatory fish: Adults and especially baby shrimp may be eaten.

6. Using copper-containing treatments: Copper can be toxic to shrimp, so check medication ingredients before treating the aquarium.
