The only thing I'm absolutely sure is that the first pic is a female, I had with her a problem with the oviducte, the eggs couldn't get out.
The second pic shows a male... probably, four people says the same thing after having seen the anal part of the fish...
But now... these fishes came in Switzerland through a Kibwana's arrival with a group of 18 P. longola... and from there, nobody can say me what are these fishes. For me, the anatomy of the mouth shows a polyodon profile... but I'm sure of nothing.
Thanks for your good questions Adrian
