Well thought my fish were doing well but just went to feed them and my estherae red had long stringy white poop. I had him in hospital tank within a half an hour and medicated with clout, but have a couple of questions, regarding the table/epsom salt the library says a handful is that what I should put in for a ten gallon tank? Also If I undertstand correctly I should not feed him? I sure hope I dont lose him but,now Im really worried about the other 17 fish. The strange thing is the only symptom I noticed was the poop he was still eating- and being active.
