I also have no evidence that this disease is transmissible - whether it's bacteria, virus, or something else. Only one fish per tank gets it and it does not spread through the rest of the population. Most of the time, I assume that the whirling behavior happens when I'm not there so any pathogen would have plenty of opportunity to spread.
I'm with the vet who believes its a relatively rare infection of specific parts of the nervous system, Willie
