Hi Knuc dog
How are your fish doing now?
The old fashioned way of curing ich is to add aquarium salt at the rate of 1 Tbs. per 5 gallons and raise the temperature to 80 - 82 degrees. Keep it that way for a week or so after all symptoms are gone.
If you can get any of the ich medicines, I suggest you do what I described above and add the medicine too. Ich can be persistent and difficult to get rid of, so don't stop the treatment too soon. If you read the article about it, you will understand why.
Good luck and please let us know how your fish respond.
