This usually indicates some sort of parasite of the gills. If there's no external evidence, it's probably gill flukes. Fortunately, most of these require a secondary host (usually a snail of some sort) to reproduce. If you don't have the secondary host in the tank, they will die out.
Ick also does this, but the parasites usually start showing up on the body of the fish before death and are easily seen. Velvet disease is another one that behaves this way, and it's harder to detect on the body (it looks sort of like a haze on the fish). Both of these will spread to other fish without an intermediate host.
