Biological species and lake range
Caridina ensifera — Lake Poso
Original pictured ecological and lineage evidence
Habitat / trophic ecogroup
Substrate-specialized lacustrine forms
Identification and species history
2007 work showed blue/red forms previously both called ensifera corresponded to separate wild species; 2021 key describes ensifera red-tinted legs and tail.
Conservation and field evidence
2009/2021 taxonomy retains ensifera distinct from blue C. caerulea.
Captive-breeder authentication
Trade claims 'red versus blue gene' for one species would contradict original field identification.
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.
