Poecilia nieuws
In August 2015 I was asked to write an article for "Poecilia nieuws" about the Killifish and Livebearer Convention 2015 in Asperen. And I gladly did...
The article has been published  in the November edition.
"Poecilia nieuws" is the quarterly magazine of Poecilia Netherlands (Dutch society of livebearers).

In the May edition 2016 an article has been published by me about the Micropoecilia picta. The pictures were made by others. I've send some pictures as well to be published but they were not of a good quality. So, I'm really glad that two other members have been offering their pictures instead.
This article was suppose to be published in the February edition 2016 but due to computer problems of the lay-out supervisor plural articles could not be published in February. So, they were all postponed and published in the May edition 2016.

The October 2016 edition contained a 4 page article written by me about the PN Asperen 2016 meeting. It was held in combination of the 41st edition of the KFN meeting. Officially PN did not contribute to the show itself. Despite of that, PN did have a small set up with several livebearers on the exhibition floor.
