Well I know their water quality is good because I change 50% a week, clean up the poo every day, and test it often to make sure it is. I am pretty sure it is bacterial and they came with it, since none of the other fish in the tank are affected. I dosed the Melafix last night after reading the "msds" online which said it was fins for loaches. My house now smells like a hospital lol. Upon closer inspection, I noticed that all 4 of them had some sort of "fin rot". When I got home this morning, one had passed away while I was at work....2 died the day after I got them. My 6 loaches and 1 DG are just fine, although the loaches seem a little more tenative today...I did a 50%
pwc and took out all carbon before I dosed the meds, and it says to do another
pwc 3 days into treatment. The water is looking cloudy in the tank today, do you think that is because of the meds?
