[Peter Finke]

Helene describes it fully correctly (only the name of the central town is to be spelled Kuantan, no “g” at the end). And the photos make it evident that you have the Kuantan-type. It’s the type of the original descriptions. The most prominent feature is the relatively short tail (most prominently in the male animal, with rays extending beyond the end of the fin) and – especially – the whitish band in the tail. In other forms (esp. Cherating) this band is blueish or greenish the same way as in the dorsal or the anal fins. There is no colour dofference in this respect. Because of the rather widespread home-range we have other forms (Pekan Nenasi or other settlements, see species account) that seem to be optically identical with the first or the second. Therefore our hitherto knowledge is that there are only two easily discernable forms, the two I named. And the most easy mark of identification is the colour of that striking band in the caudal.
