Also, I am assuming that no new fish or corals have been added so it probably isn't some other pathogen like marine velvet. It sounds like you simply transferred the entire contents of the previous owner's tank to your house which in effect is just like a tank transfer.

Anyway, keep an eye on them and report back if they start behaving strangely like gasping for air at the water surface, or if they stop eating or if they seem lethargic and not swimming much or constantly scratching their sides/gills on rockwork, etc.
