It appears that my (baby) blue hippo tang may have come down with a case of ich. My yellow tail damsel has been picking on the tang since I put him in 2 and a half weeks ago, but the tang didn't really seem to care. They are about the same size. I went out of town this past Sunday, came back today(Thursday) and the tang was covered in white spots. He keeps trying to rub up against the rocks and powerheads I could not get a pic today, but it looks like the pic's when I do a Yahoo search on ich. I read that I will have to remove all of my fish for at least a month. Put them in a QT tank and start treatment. I have read a few different things. How do you think I should treat this ? How can I be sure it's ich ?
