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.
