I purchased a Chevron Tang a few weeks back. The LFS has had it in their 3000g frag tank for a 6 weeks. I am waiting one more week to bring home because my QT is currently full. When I get it home next week, how long should I QT for? Should I run a treatment of Cupramine followed by Prazipro before going into the DT. I plan on running the Chevron, Pearly Jawfish and a Valentine Puffer on this QT cycle of fish. I've read some people just QT with no treatment, but I am paranoid that it could be hosting something and just won't show signs while in QT.
