It was the concensus of a panel of conservationists and ichthyologists that used markers in mitochondrial DNA to determine genetic links between S. formosus and the phenotype species. The original plan to separate the farm-developed phenotypes was presented by parties with interests in the aro farming industries.
The original list included 4 phenotypes. The batik (S. inscriptus) makes the list 5 since 2012.
