Thank you both for your input in terms of the qt! I am glad to hear that the 29 gallon will work of for this. Corydude, do you think that I should fill the 29-gallon with the water from our display tank to avoid a surge of ammonia, etc? Alton, yes you are correct about cowfish as they do acquire ich readily. Unfortunately we have just not been able to rid ourselves of it. We'll go through these cycles where it seems as though it is gone and then one day the white spots reappear. Unfortunately we lost one of the clowns sometime during the night and the other one had more spots on it this morning. I re-treated with the Ich Attack but we just have not had a lot of success and unfortunately have lost many fish to this parasite.
