Identity and naming
Catalogue name: Orange Eye Blue Tiger
Biological identification or trade attribution: Caridina mariae complex (trade attribution)
Classification: Caridina
Evidence grade: Trade morph; pedigree unverified
Appearance and differentiating traits
Blue tiger body with conspicuous orange eyes.
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
Eye appearance does not establish a documented founder or pigment locus.
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.
