Mine was a 30 gallon too. Mine was in for the same amount of time as yours too before the same thing happened. This is exactly what I went thru. The advise here from the pros saved my tank and yes it cost me a tang but I saved the rest of my tank and learned so much from it. A tang will not make it in your tank and will decease the rest of it if you don’t get it out quickly. All your problems will go away once you do.
I really appr the advice here, but it was just misleading direction that got us here and now I'm not sure what to do. We don't have room for a 6 foot tank, and Petco won't refund but I'm not sure they'd even take her back with ich. So I have to keep pursuing hyposalinty treatments just to maintain her bare minimum quality of life and risk infecting my clown?Nemi will work but Dori won’t work unless she has room to “just keep swimming, just keep swimming”.
