One can even be more precise:
This is very clearly a male P. nagy in der terra typica-Form Kuantan. The caudal indicates definitey Kuantan (as opposed to Cherating or other variants) because of two markers: the broad white band inside the fin (as opposed to a blueish with Cherating) and the free spins overshooting the fin at the end which are very typical for nagyi Kuantan.
You should be happy for getting this species and form. It is ridiculous to sell it as “quindecim”. Nobody with eyes in the head and some brain can get these two confused, even females not.
