2009 and 2010 original phylogenetic research
Malili habitat-specialist diversity includes rock, deeper rock, wood, leaf-litter, open-water, sponge and generalist species. The 2010 mtDNA study inferred two independent riverine colonizations, but does NOT establish an aquarium designer-shrimp pedigree.
Poso color confusion resolved
The 2007 red and blue forms once lumped as ensifera were clarified in original later taxonomy as distinct C. ensifera and C. caerulea; 2021 field studies also describe additional endemic species. Neither observation establishes an inherited aquarium Red Cherry versus Blue Dream locus.
