Ok, I have a yellow watchman goby that came down with ich. Now, I give all my fish a close examination every day (they are right next to my desk... and i get bored a lot) I just spotted it today, pulled him out right away and placed him in a QT. Now, my question is... do you think the ich already had time to drop off of the goby so it could start to reproduce? I am tempted to go buy a UV
sterilizer to ensure that the ich doesnt make it into my other tank (I have two different tanks linked by the sump). Do you think I would be ok without it? I would rather not go spend money that I dont really have right now, but I also dont want to take a stupid risk of all my fish coming down with ich.
