Zahar, it’s clearly no deissneri. Whether it is a true bintan, is open for discussion. It’s near to it, since it looks very similar to it, but I hesitate to already claim it identical. There are two probems: (1) It’s definitely caught at a location different from all knowm hitherto in the literature or by personal information (Linke, Kishi) because all of these locations on Bangka were completely destroyed in 2016 already (dry, no blackwater anymore, even mostly no water at all = prepared for being used as arable land for planting oilpalm trees). Of course, bintan has been reported from Bangka formerly and it is possible that it occurs still today there at some other place. (2) The second problem is that we have other photos of a non-deissneri from Bangka that looks a bit different than your fish. I prefer to keep the species identification an open question.
