Cories are stressed at temperatures above 75 degrees and most tetras on average get stressed above 78 degrees. You cooked your fish. It amazes me how so many people in these forums describe Ich as a deadly disease when in fact it is the treatments which are killing the fish. Hasn't anyone ever heard of Coppersafe?Now at 86 for 4 days.lost 2 corys and 1 tetra.

I agree that the treatments more than ich itself are the cause of fish losses with ich, but I do not agree with the rest.
The only safe way to effectively eradicate an infestation of ich is to increase the teemperature to 30C/86F for one to two weeks. Most tropical fish can easily handle this. I have twice done it with two different tanks of wild caught cories (50-60), loaches, characins (tetras, hatchetfish and pencilfish), Farlowella, and barbs. If it is a particularly stubborn ich, as sometimes occurs, adding aquarium salt with this temperature can work, I did that once.
None of the so-called ich treatment chemical concoctions will work as safely or effectively as heat alone, or heat & salt if necessary (rarely is). I learned this from Dr. Neale Monks, and in discussions with Ian Fuller about Corydoras he too agreed on the heat over chemicals.
The OP here did cause more stress by not following our instructions in two other threads. The initial heat increase was not anywhere near sufficient to deal with ich, so that did add stress to the fish with no benefit.
It is actually never safe to dramatically increase the water temperature on fish. When refilling a water change it's actually safer to have the new water a little cooler than a little warmer than the original. I see this nonsense on fish forums all the time about raising water temperature and using salt to treat a parasite as fragile as ich which is easily treated with Mardel's Coppersafe or any medication containing malachite green (with very careful following of instructions) It is true Coppersafe isn't safe for inverts but neither is salt for them or even some fish like plecos (not to mention plants).
Personally I haven't had a case of ich in over 25 years because I learned quick not to do dumb stuff that stress my fish.
And when I have professional marine biologists, ichthyologists and microbiologists agreeing on this, I tend to listen. They are the experts with far more knowledge and understanding than all of the rest of us combined.
82F is not enough to kill the ich. You’re stressing you’re fish by doing that with no positive results.Just as a post script...I have had temps now for 7 days at 82F followed by a 50 percent water change and a subsequent increase in temps to 86F.All through this period I have been treating with Petco herbal based parasite remedy....Results so far,lost about 4 corys and two tetras. Only one fish has remaining dot on eye..Turned down heat to 82F today .
