If you have never joined a specialty fish organization like the American Killifish Association you should. There are many here in the USA and abroad. There are groups for cichlids, livebearers and Bettas to name just a few. They have shows and conventions and monthly newsletters and journals. I just got my newest Journal of The American Killifish Association. These journals are not typical hobbyist publications but downright scholarly . Most of the writers are professors and researchers. Best of all is that your dues put the kibosh on most advertising. All that's in here is http://www.jehmco.com on the back cover and a small ad for Zoo Med Laboratories on page 44. The fish on the cover is Fundulopanchax gardneri Innidere .
