So what would my situation be? I have setup at least 20 tanks in the last 4 years and have never had ich. The only fish I qt'd were my tangs and an anthias and then it was a 55g qt with live rock and the works. No stress there. I have not qt'd since then and have still seen no ich...would this mean my tanks are ich free? They are defintely large enough for the fish I put in each tank so that shouldnt be an issue.
I have however, at the beginning had an outbreak of what I believe was marine velvet. It wiped out most of the fish I had in a matter of maybe 3 days. The tank was large enough, water quality was great but still I had losses. BUT I also introduced a sick fish to that tank which was the way it came in. Maybe not a great example as velvet is a horrible and fast acting disease but thought I;d throw that in.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
