Well the 3 fish I had in my 44g is now down to 2 fish. The flame angel died today. It was fine up until about 3-4 days ago when it stopped eating and got a white circle on it's stomach. The tang was doing worse than before so with the help of some people on here I realized my ph was low due to the hyposalinty treatment. So have been dosing with dkH buffer and monitoring ph for the last few days and keeping up with the 20% daily water changes and new vitamins in the food. So I figured the flame angel would come around and start eating again, guess not he died today. The yellow tang isn't really looking better, he may actually have a few new red spots on him and the lemonpeel angel has been unaffected by any of this. Am I just having horrible luck lately or what? I guess I'll keep this up a few more days then switch to the medication route if he doesn't start looking better. On a positive note I guess both remaining fish are still eating well.
