Adding new fish to an established system without proper quarantine can spread disease from the newly introduced fish to the established stock or from the established stock (which may be healthy, but may be a "carrier" of pathogens) to the newly introduced fish. Following quarantine, especially with very valuable fish, one suggested protocol is to place one or more fish from the established stock with one or more fish from the new group for a week or two to determine if there is any lingering disease. There is some debate as to whether infected fish can be successfully treated for these bacterial diseases. Individual fish swimming unsteadily or randomly.
