The banding apart, there are differences in the colour of the pelvic fins ;
those fish from Borneo have reddish-orange fins with black, whereas the fish from Sumatra have entirely reddish-orange pelvic fins.
Most of the fish in captivity appear to be from Borneo stock.
The changes in "band pattern" could just be natural variation of course ?
Strangely there is also an "albino/very pale and yellow band patterning" variation also sometimes seen in captive stock.
