I have an ORA orchid dottyback and gold sailfin blenny coming tomorrow from LiveAquaria (DD), and I setup a QT tank (actually just leftovers from when I was going to do a treatment tank for my magnifica). I don't have any fish medication yet, and was just going to hold them for a week or two in the QT and medicate as needed. I have little experience diagnosing, but I guess I can tell if something has Ich or looks bad and then I figure I'd just look it up once I can see a problem and purchase meds as needed. Then I know there's the whole TTM method for Ich. Not sure if I want to go through all that (or have the time at the moment). Here are my questions: Should I do preventative medications even if I don't see any symptoms? If so, which ones? I never QT'd my Geometric hawkfish, I just took a big chance and I guess I got lucky. My clowns are all from captive bred systems (Sustainable Aquatics) so I never bothered. But with LiveAquaria order, I think it would be best if I did. Any votes for not necessarily needing QT or just do a light one for preventative measures? Is the whole Ich TTM really required?
