I have a friend who just got some new fish from somewhere that she had gotten fish from many times before without any issues.
However, after introducing them to her tank, it turns out they had VHS, and it started to infect her other fish.
This was something I'd never heard of before. I am planning to get fish of my own in the near future, and was wondering what to do if my fish ever caught VHS. Is it possible to cure them, or prevent it from spreading?
