I'm glad she's doing better! The bloat worries me, but I can't think of anything else you can do for it right now.... The Kanaplex should help if it's bacterial, and the Epsom salt should help if it's just fluid retention. (And you already know about using something like API General Cure if it turns out to be parasitical.).
You could.... but if it's a gram negative bacterial infection, I would combine Kanaplex with something like a furan medication (API Furan 2, Bifuran or Jungle Fungus Clear) instead.... What are you trying to cure?
