I have a 30 gallon reef tank that was going great until I added 2 clownfish that under closer inspection had ich. Asked my LFS if I should qt them since i never had a problem before with his livestock. Now I have a huge problem. My qt tank is not ready since I was treating my older clownfish that died. Do I have to cycle my qt tank to put my fish that have ich? I have 5 fish total and I'm not going to be able to treat them all at once. I'm really really head scratching here? How should go about treating my reef tank?
