This is part of the ongoing effort of systematic ichthyologists to decry the legitimacy of results published in what is known as "gray literature" (e.g. aquarium journals and other publications that are not peer-reviewed).I had a talk with Sonia Fish-Muller, Claude Weber, and other Ichtyologue friends form the MNHN, all of them do not recognise Panaqolus and other genus form that Datz special. And I am almost sure that most if not all Brasilian Ichtyologs do not recognize it either.
I don't want to digress any more on this lest we go off on a tangent (plus this is a subject that I have passionate feelings for and I would have a lot to say).
Suffice to say that a long time ago, I had considered publishing descriptions of new species in TFH. I am now glad I never followed up on that, for that would be tantamount to commiting professional suicide
