i am treating my 7 gallon tank for Ick still (but I think that tonight will be the last treatment-it has been a week already ??) This morning when I got up I found one of my Albino Cories was dead. He was alive last night and I didnt see anything wrong with him. I was watching the tank before I added treatment (but not too much after). My water if fine so I am not sure what killed him. I did buy him as an adult at the pet store almost 3 weeks ago. Could he of been old?? Im kind of clueless.
