Answer 1

One virtue you have to have when treating illness in an aquarium is to be patient. Ich can take weeks to fully eradicate, so don't be surprised if you are seeing spots for awhile.



Don't listen to this "no water changes" nonsense. Water changes (with gravel vacuuming) remove the free swimming parasites from the water, and keeping your lights off may reduce stress on the fish, but it's not going to help eradicate the parasite.



Raise your temperature to 86 degrees over a matter of 12 hours or so. This temperature is enough to stop the reproduction of the parasite, and speed up the life cycle of the existing parasites.



keep treating with ich medication also, but only use a half dosage, as corydoras and other scaleless fish are sensitive to medications, and normal dosages can sometimes kill them. I would normally recommend using aquarium salt also, but again, scaleless fish are sensitive to this too and it could potentially be harmful in conjunction with medication in the tank.



Most of all, have patience. You could also quarantine any fish that look really bad, and give them the regular med dosage in a separate hospital tank. Don't forget to do plenty of water changes on your tank, 40% as you said you did is a good amount.

Answer 2

You need a treatment for ich from your local pet store - work out your tank volume and treat according to the instructions.



During treatment dont do water changes - keep the tank lights down low as this confuses the ich when in the free swimming stage as it is light orientated and it can help to keep them in the free swimming stage which is the only one where the chemical can destroy them.



Usually the treatments follow a 3 day pattern to follow the life cycle of the parasite - some ich treatments have a bacterial protection with them too to stop the fish developing fungus from the wounds inflicted by the ich.



Treat as soon as you can as it multiplies at a tremendous rate if untreated - I hope you dont lose any more fish to this terrible fish disease - it is always best to have a small quarantine tank for newcomers to check they are free of disease before adding them.

Answer 3

Ich only kills already sick fish this fast. Perhaps your organic chemical is sucking too much oxygen or killing your cycle. You can't treat ich when its attached, all you can do is a daily gravel vac/water change to remove free-swimming ich and keep parameters good.
