Good Luck.

Definitely sounds more like velvet to me.

Trust me velvet looks like ich to start out with and it kills freakishly fast. Within 2 weeks of adding a fish that had velvet to my tank I lost a total of 24 fish to that disease with 2-4 fish dying each day everyday for a week straight. Most horrible thing to have to go though. I left my tanks 8 weeks fish free to get rid of the velvet. Lots of info on marine velvet in my signature link if you're interested.
