My female Parachromis friedrichsthallii "La Ceiba" (my avatar is a picture of the pair) stopped feeding 3-4 days ago and began producing white to transparent faeces a couple of days ago. She lives in a tank with her mate and a pleco, both of which are fine. The male La Ceiba is still eating like a pig and producing normal-looking waste. She does not appear visibly swollen, but she completely ignores all food, even when the male devours pellets right in front of her. I looked at this thread: http://www.monsterfishkeepers.com/forums/showthread.php?523470-Treating-Hexamita-aka-Spironucleus and it seems that infusing food with magnesium sulphate is the only effective cure for this disease? What happens, then, when the fish does not feed at all? Also, I have no idea how she got infected, it is my first time in 8-9 years that I have had to deal with bloat/Hexamita/whatever it's called now. Will it spread to the male? I don't have a spare hospital tank or anything at the moment. I will greatly appreciate any input. Thanks for reading.
