In contrast, the feminine fish who were kept isolated did not proceed to exhibit the male regular behaviours after testosterone was discontinued. There are many species in the genus Betta, most people of which are very morphologically similar. Within Thailand alone there are twelve nominal species with new species being found every 5–10 years. Past efforts to distinguish Betta species were in line with observable morphology, but given their visual similarity, this approach has masked much of the cryptic variety in the genus. Recent speciation efforts have included use of DNA barcoding to differentiate species, specially comparing the CO1 gene of the mitochondrial genome, resulting in new theories concerning the relatedness between species and permitting for the building of new phylogenetic trees.
