Hi so here I am with another problem! My largest and probably oldest platy has what could be a fungus on her lower lip. It was not there yesterday because I was taking pictures of her then I will get more pictures tonight if it is still there but I am about to go to work. I think it could be cotton wool fungus? My question is how do I treat it? I have some methalyne blue, and some anti fungus treatment. My water parameters are fine 0,0, >10 API mater test kit I did a water change on Thursday 40%. I think this fish may be nearing the end of her life span. Yesterday she did a flip out of the water into the fry net (and had a feast!) so maybe she hurt herself doing this which may have resulted in a weaker immune system. I have heard that maracyn? is the way to go but I can't get hold of this anywhere I believe its because this is an antibiotic so hard to get over here unless anyone else in the UK knows where to get it? So anymore ideas?
