All the fish are dead or pretty much dead:(

If you can get the fish out and into quantine, try and do it in a barebottom tank with some pieces of pvc piipe. Do a good water change every nitght, clean the pepes, and clean the tank bottom.
Keep all fish out of the main infected tank for at least a month, even 5 or 6 weeks to be sure, the icks life/reproduction cycle will last up to a month. Don't give the ick a host , break its life cycle.
There is quite a few good papers out there with lots of good info (google). I had a great link but am having trouble finding it. Will post if I can locate it.
