Help spots forming on fish.

[neoh]

I've overcome and saved fish from ich - but you have to act fast *if* it is indeed the parasite. I would keep an eye on it no more than 12 hours from initial inspection. If any abnormal symptoms start occurring, get them into a quarantine tank asap and start a hyposalinity treatment.

Use tank water for the initial quarantine tank then transfer all your fish (yeah - all of them). Tank needs a filter, not really heat but - doesn't hurt. No powerheads, just a tank and a filter.

Slowly start doing water changes by removing the water and putting fresh water in. Do this over a period of 24-48 hours until your salinity is between 1.008-1.010 and maintain it for 6-8 weeks until no signs or symptoms occur. Check for spots, if spots are still seen - another 6 weeks in QT.

My fish are about 5 days away from getting put back into the DT.

I hope it's not ich. But hyposalinity works. I also have cured (cured?) ich with a 8 week cupramine treatment, but it does take it's toll on the overall health of the fish long term and would consider hyposalinty over the latter.
