Identity and naming
Catalogue name: Amano Shrimp
Biological identification or trade attribution: Caridina multidentata
Classification: Caridina
Evidence grade: Science-backed species; separate life-cycle group
Appearance and differentiating traits
Transparent to grey body with rows of dots/dashes; algae grazer.
Color/grade depends on shell thickness, lighting, body tissue, age and stock; the listed trade phenotype is not an official diagnosis.
Genetics, breeding and lineage
Former C. japonica name in aquarium history; larval development requires brackish/saline phase.
For a verified lineage, record maternal and paternal source, dated mating pairs, F1 and F2 phenotype distributions, outcrosses, culls, and independent photographs. Neither an assumed recessive allele nor an exact cross ratio is assigned without actual breeding data.
Care, propagation and risk
Match captive-bred adults to the supplier-colony water chemistry, not to a genus-wide recipe. Test conductivity, temperature, GH, KH and pH and maintain stable mature biofilm. The genus Caridina contains both soft-water Bee lines and distinct Sulawesi/diadromous taxa; they do not all use one protocol.
Quarantine imported or newly acquired colonies; do not release aquarium shrimp into natural waterways. Preserve line labels separately.
Authentication and look-alikes
Demand original breeder and locality records where historical claims are made; trade name, coloration, seller photograph and a competition class are not proof of species, allele or parentage.

These sources support the scientific identity, commercial naming, or contextual observations identified in their labels. They do not establish a genetic pedigree for this particular specimen or colony.
