After some thought it scares me.  I just bought about 800 in fish and I have a hard time rationalizing the well being of everything i just bought for one fish.  Sorry i made my previous post, just wanted a powder brown when i ordered and they were out of stock.  I know that stinks but its whats best for my tank.  To answer your question i am in firestone.  And to be honest if the ich is that bad he will more than likely not make it.  Treatment usually takes a few days to a week with hyposalinity for ich.  At least based off my experience.
