No, I am very sorry, but Anthony’s picture does not display the real deissneri. It’s displaying a fish of the bintan-group with a slightly pointed caudal fin and some brownish-reddish tinge in it’s unpaired fins.
To compare with deissneri please refer to our species account and the pictures over there. Even when very young the deissneri-males have a markedly pointed caudal fin with a black filament just similar to filamentosus. Even the females have a short filament but not as long and conspicous as in the males. The hyaline stripes in the dorsal and anal fins of the males are completely broken up into single short stripes standing much more upright. The most typical is that marking in the caudal: Never a continous band, always the characteristically distinct short stripes which run strictly parallel.
Anthony: Is your picture intended to show us the fish that is offered as “deissneri from Bangka”? Then this offer will not be deissneri. But perhaps the picture is really an old one used for illustration purposes by your partner in Asia. Then, it must remain an open question whether the “deissneri from Bangka” in the new offer will really be deissneri. The fish offered may well be caught on Bangka. There is bintan occurring on Bangka and there is some rumour about a third species of a bintan-like form. But maybe it’s deissneri. That is possible, of course. But then it must be another fish than shown on this photo.
