Currently treating Hexamita (I believe) with Epsom salts, not having much success. Fish not eating for the last few weeks, after eating a small dither which I believe gave him the hex. did 4 days of injecting Epsom salt down throat with pipette, have dosed tank with Epsom salts and tried to feed Epsom-soaked pellets but he won't eat them or anything else. Fish is shedding mucous membrane of intestines (white stringy "poop") every day. Will try this for a few more days, if no success might go the metro route.
