Biological species and lake range
Caridina caerulea — Lake Poso
Original pictured ecological and lineage evidence
Habitat / trophic ecogroup
Lacustrine fine-substrate/rock habitat
Identification and species history
2009 species formalized a blue-colored former C. ensifera lookalike, with 2021 key noting blue tail fan marks and blue rostrum.
Conservation and field evidence
A second distinct wild species rather than recessive blue morph of a captive red shrimp lineage.
Captive-breeder authentication
No link to commercial Neocaridina Blue Dream gene.
Published captive brood counts
No scored captive F1/F2 color segregation or exact parent IDs in these sources
Inherited commercial color traits
Wild-species phylogeny and habitat grouping only, no commercial color gene allele
Ethical conservation and species verification
Keep documented captive-bred stock with provenance and stable species-appropriate conditions; never release aquarium stock to natural waterways or interpret this record as authorization to collect, relocate, or purchase rare wild animals.
