Ok, so thought the disease was gone but then it appeared in a 20 gallon tank of mine. Don't know how it got there but just lost 2 peacocks with velvet and fin rot on them. The calvus in that tank has ich, the ahli hap is still not showing symptoms. Raising salinity in that tank with the last 2 cups of salt I have. That would put it at the same 50 percent salinity as the other tanks. I'm out of money and time to deal with this right now totally sucks.
