Is hole in head contagious?

How does ‘hole-in-the-head-disease’ occur? The disease occurs mainly in discus and cichlid species, but it can affect other species such as gouramis.

Astronotus ocellatus has bright eye spots, called ocelli, at the base of the caudal fin. Winemiller (1990) examined whether the eyespots serve as a defense mechanism against fin-nipping piranhas, Serrasalmus and Pristobrycon. The main food source of these piranhas are the fins of fish.
