I have a 90 gallon tank with 4 flame wrasse(PRICEY!!), a small powderblue, and a small flamefin tang. The powder blue and one of the flame wrasse are showing signs of what I believe to be ick. The only question is, early in the morning, the powder blue has some balck spots. Are these spots where the ick has damaged the skin, or is it black ick? I have a 65 gallon I'm getting ready to set up as a qt for all fish....the standard sponge filter, power head, pvc. My question is, should I run hypo or copper? Any other suggestions. I plan to keep the tank fallow for at least 4 weeks. I don't have a refracto, so hypo could be difficult. I could get one though.
