Hi from pepperdog. I have a 70 gal
. tank with 4 large beautiful goldfish. I have had them 4 years , putting them out in my pond in the summer. All of a sudden One fish started getting white lumps under the skin and soon it started spreading to other fish. I have been everywhere, asking everyone, showing pics. I have gotten so much conflicting advise I am going crazy. Trying every cure on the market hoping I will come across something. My water tested way high for nitrates and nitrites so now I am treating that with bacteria and water changes- 50% each time. So that is where I stand and who I am. My knowledgable fish guy at Petco suggested this site as the best fish site around.
