Crystal Black Shrimp at a glance
Adult size: 1 inch · Minimum tank/pond: 10 gallons · Difficulty: expert · Diet: omnivore · Lifespan: 1-2 years.
Crystal Black Shrimp (Caridina cantonensis) is a freshwater invertebrate kept by aquarists for planted-tank cleanup crew + breeding-line collecting. Demanding requirements make this species best for keepers with established mature systems and proven track records.
Where Crystal Black Shrimp comes from
Crystal Black Shrimp (Caridina cantonensis) is native to freshwater habitats across multiple continents. The captive-bred Crystal Black Shrimp sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
Crystal Black Shrimp tank size and setup
Crystal Black Shrimp requires a minimum of 10 gallons for healthy adults. The minimum is based on the species' adult size (1 inch), territorial range, and behavior pattern. Most Crystal Black Shrimp sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Crystal Black Shrimp setup: mature planted tank or low-stocked community tank with stable parameters, mineralized substrate (or remineralized RO/DI for Caridina), low-flow filtration that does not suck up shrimplets, and minimal copper exposure (avoid copper-treated medications).
Crystal Black Shrimp prefers freshwater parameters: Temperature: 70-78°F pH: 6.5-7.5 GH: 4-12 dGH KH: 3-8 dKH Ammonia + nitrite: Both 0 ppm Nitrate: Under 20 ppm long-term Copper: 0 (especially critical for invertebrates)
Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.
What Crystal Black Shrimp eats
Crystal Black Shrimp is a omnivore. Eats a varied diet of pellets, frozen foods, and supplemental greens. Quality flake or pellet (Hikari, New Life Spectrum, Tetra) plus frozen mysis or bloodworms 2-3x weekly produces best color and behavior. Feed Crystal Black Shrimp appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Crystal Black Shrimp tankmates and compatibility
Crystal Black Shrimp works alongside peaceful community fish. Avoid mixing with fin-nippers (some tetras, barbs), aggressive cichlids, or large predators. Best in shrimp-only or mostly-shrimp tanks for breeding success - any larger fish will eat shrimplets.

Crystal Black Shrimp adult size and lifespan
Crystal Black Shrimp reaches 1 inch at adulthood with a captive lifespan of 1-2 years with proper care. Females carry eggs under the abdomen until hatch; in stable tanks, breeding populations sustain themselves indefinitely.
Can you breed Crystal Black Shrimp?
Yes - Crystal Black Shrimp is one of the more readily-bred freshwater invertebrates. Provide stable parameters, a mineralized substrate, plenty of biofilm, and avoid copper. Females carry eggs 25-30 days; shrimplets are immediately free-living and eat biofilm/algae.
Common Crystal Black Shrimp diseases and problems
Crystal Black Shrimp is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Crystal Black Shrimp for 4 weeks before adding to your display tank. Treat fish in a separate hospital tank to avoid affecting plants and inverts. Most disease outbreaks trace back to poor water quality, chronic stress, or skipped quarantine.
Where to buy Crystal Black Shrimp online
