Hello all,

I need urgent opinions n help.

Tuesday morning I found white cotton-type patches on my 4 Gold Sarasa Goldfish - Ich!!
My tank is 60gallon, with one cave type ornament, 2 luck bamboos, couple of anacharis plants.
The goldfish are 6-9inches long. Been with me for 2 years without any disease or illness (they were 1inch or so back then). I had an emotional attachment with them since I have seen them grow into these beautiful, elegant Goldfish.
I treated the water with API Ich control. Added salt according to the size of the tank and raised the temp to 80. I have stopped running both the filters. The air is on though.
One of them died Wednesday morning. The other 3 are still floating in a corner, occassional swimming, and not eating.

Is there anything else I should try? How long will it take the Ich to be removed? what are my next steps? will this come back and will this affect the fish if they survived.

Thanks,
