So I just discovered my poor guppy's mouth! What is wrong with her and how do I treat it?! I'm currently treating the tank for Ich from another guppy (which seems gone now but only a week in) and actually just bumped the temp up from 85.x to be over 86. I've also been treating with garlic. I was looking everyone over and noticed her mouth. Please help! Based on this article http://www.monsterfishkeepers.com/forums/threads/treating-mouthrot-mouth-fungus.21286/ I have moved her to a 2 qt pitcher with lid (not sealed, just so she doesn't jump out), thermometer and bubble stone with some of her own tank water and sitting under a lamp so the temp will slowly drop. I have some other heaters but nothing that small. Hoping I've caught this in time and that someone local has a treatment I can get tomorrow!
