I have ICH *SICK* &Mouthrot in my tank, lost our goldfish last night I keep reading to raise the temputure and add salt BUT....not all fish can handle higher temps right? I'm new to this & just want to help my poor fish! I had treated for ich and then for the fungus but it seems neither is leaving! I've done PWC & my water is good as far as all the stuff it needs to have so....what am I doing wrong? Thanks for all your imput!!
