Seems as though killies have their own ecosphere in the hobby. I am just now learning more about them and the more I delve into their idiosyncrasies and environmental requirements, the more fascinated I become. The one thing I think that stunts their popularity is the fact that they need cool water to thrive. The Flagfish is one of the few that will live in tropical temperatures and as such, is a good choice for us non-specialists. Now I'm lusting for a chiller.
Moose if you get some id love to see a journal started about that tank, Killifish are my Favorites! Ecspecailly Bluefin Notho's! ive only had killifsh once before and want them soo bad again, the first time i just never had the right equipment for them along with habitat, water was far too warm for them
