Ok well My uncle has a Yellow Tang and added a Powder Blue Tang. It got ick once which he then caught it and sent it to the LFS
. It got better and put it back. Again Ick. He couldnt catch it. I caught it today with dads help in 5 minutes. It is completely covered in ick with film over its eyes. I have it at the LFS
until monday or tuesday when i will take it home to a 20G QT i have. The tang is only 3" long. Is it ok to keep it in a 40 Gallon for a few months? What meds do you recommend?
