The first and oldest Killifish association, also the worlds first global specialty fish club (1961) and first mailing list about tropical fish (1986). Covers North Americas: Canada, the United States and Mexico.
I go to a show and take crappy pictures. Hristo Hristov goes to them and takes photos that end up on the covers of magazines. Like this one...
Multiple regional clubs exist also, ie, west, south.
