It seems you're the only one willing to help with my troubles

I thank you!
I just so happen to have Pimafix on hand, I will dose as indicated.
I am doing the water change now.
Poor little guy!
So daily water changes from here on out then? 50% daily?
After this goes away, how often should I really be doing water changes? I hear different stories. A week, two, 50%, less than 50%. Ugh!
