His being a goby is very much in your favor: they almost never get it, and if they do, usually a few spots and its gone. Blennies, gobies, and dragonets are bottom-dwellers, and tend to encounter it a lot more than most fish: they seem to have a natural defense.
Ever since I have become very meticulous about water quality [dating back to the 1980's] I have not lost a fish to ich or velvet. I've lost fish to accidents, predators, and things like that, but any ich outbreak I had was not tank-wide and did not result in fatalities. It's not all luck: I keep more blennies and gobies than other species [but not exclusive] and I also have a lot of corals---I have my own notion that corals may actually eat the freeswimming phase of this parasite: they eat everything else in that size range. I don't know why that should be an exception. So for whatever reason, good water, corals, and a lot of fish who don't get it, I've lucked out. Any outbreak I've had, and I can about count them on the fingers of one hand, has been brief and just as you describe. I do feed garlic, believing in belt and suspenders, whenever I have a new fish in the tank.
