Hi Pktybs
It would indeed also have been very surprising to see p. quindecim for sale in a shop. Wonder how come they suddenly come up with that name.
Its easy to rule out deissneri. That would be equally rare, – and it would have to show the spike tail, which is easy to see.
P. nagyi is possible, – but again also quite recognizable, but of course the males will need to be mature. However if you have had them for 2 months, I would feel that you would have by now at least seen a glimpse of the brownish nagyi typical colouration.
sp. blue line, sp. bintan is probably more likely. These are fish that we see rather often, there are many variations, – so therefore the chance that it may be a variation is bigger than it actually being p.bintan. But they will belong to that type of fish.
I am sure, anyway, that Bill Little should be someone who might indeed know if anyone else has bought and seen some of the ‘p. quindecim’ at wet spot.
