ok, i've been having an ongoing problem. for about 4 months now i've been losing fish, mostly livebearers. i can't seem to find anything visually wrong with them. here's the scenario. they eat normal but seem to waste away. the gut sucks in and is actually indented. the back gets a hump right behind the gills. no fish stores in my area seem to know whats wrong. any ideas would be appreciated.
i have a 78 gallon, ph was low but taken care of that now, amn, nitrite and nitrates are fine.
