Of course there are photos. You cannot decribe a new species nowadays without including photos. One is shown in our species description. It was taken of the specimens which were brought to Europe by its discoverers, and it is shown in the scientifis species descrition by Linke and Schindler, too.
I had my P. gunawani from this small stock of animals wild-caught by my friend Horst Linke at the original location, and bred them without any difficulties. But then, things happened that often happen: I gave them away and the parent fish and their offspring were lost completely by the new owners.
This photo and othere photos (including a female, a freshly caught individual and photos of the original places and catching situations) ate to be found an pages 415-417 of Linke’s “Labyrinth fish world”.
All other photos which I have seen in the net proclaiming to be “gunawani” are definitely or most probably not that species. The trade likes to sell “new species”, it’s a marketing gag. But since there are good photos of the original individuals, one can easily tell those to be wrongly named.
